Hi:

I am using the Elegant.Ui.Label and also the System.Windows.Forms.GroupBox and I would like to know how I can apply the ForeColor of the Elegant.Ui.Label to the ForeColor of the System.Windows.Forms.Groupbox?

The code I am trying to use is not changing anything for me.  Any ideas?

        For Each ctrl As Control In Me.Controls

            If TypeOf ctrl Is System.Windows.Forms.GroupBox Then

                ’Take the ForeColor of the Elegant Label and apply it to the

                ’Windows Forms GroupBox ForeColor.

                ctrl.ForeColor = Elegant.Ui.Label.DefaultForeColor

            End If

        Next ctrl

Actually, the DefaultForeColor property is not part of the Elegant.Ui.Label class. It belongs to the System.Windows.Forms.Control class.

If I type in Elegant.Ui.Label., intellisense gives me the property DefaultForeColor in the drop down menu.  How am I going to be able to assign the ForeColor of the Elegant.Ui.Label to the ForeColor of the System.Windows.Forms.GroupBox?

You can do that by using the following code instead:

ControlSkin skin1;
Color color = Color.Empty;
if (SkinManager.TryGetSkin("Label", out skin1))
    color = skin1.GetPaintInformation(ControlState.Normal).ForegroundColor;

This code doesn’t look like VB.net and when trying to use it, I get errors of undefined values all over the place.

Hi:

If I use the Visual Basic TextBoxBase class, I can access the .SelectAll member for TextBox and MaskedTextBox without an issue.  However, if I try to do the same thing with your control, I am unable to access the .SelectAll() member.

Any ideas?

Thanks!

I need to add a multiline text box to my form.  I can do it with the Visual Basic TextBox by setting the MultiLine property to true; however, I am unable to find this in the Elegant.Ui.TextBox properties window.

Please advise,

Thanks in advance.

Elegant Ui TextBox has been featured with a multiline layout starting from version 3.3.

Now that I have upgraded to v3.6 and have my license key, do I then just download and install the v3.6 from http://www.prof-uis.com/download/ElegantRibbonSetup-v.3.6.exe?  Will everything be upgraded without me having to redo my application?>

It it should work in the way you described. You will not have to redo your application.

When I upgraded from v3.1  to v3.6, it blew up my whole application.  No control references could be found so I deleted my project and started fresh.

The only thing you should do is to update project references. There is no need to start the new project again.

Hi:

I have just gone and purchased v3.6 of Elegant Ribbon.

I am using an old version it looks like.  v3.1.

When attaching a context menu to a ribbon button, if the application is running on a secondary monitor, then the context menu pops up on the primary monitor.  Is there a fix for this?

Hi Guys,

Is there a zoom bar for the ribbon?. 

Traditionally this would go in Status bar in the Controls Area and get used to control the ’zoom’ on what is being displayed on the main form.  Most of the ’opposition’ have one but I can’t find one in Elegant Ribbon.

If you do not have one and do not intend to provide one, is there a suitable control ’out there’ that could be adapted?

The control (slider/track bar) will be available in version 3.7, which should be released within a week or so. See the screenshot below.

Hi Guys,

Excellent news, any hints at what else is comming?

John

The major new features of version 3.7 include:

1. Backstage view
2. Slider
3. Message box
4. PictureBox control
5. Memory usage optimization

I have a ribbon control that contains one tab and several groups.  As I only have one tab, is it possible to disable or hide the tab selector at the top, as it is redundant?

Thanks

Ian

i am using the Elegent Ribbon controls in my desktop project but here the tap page show() method does not work ,
I want to show the tape page tabpageEmployee when i click on btnNew, but it does not work , can anyone help me

Greetings and Happy Fourth of July -

The fix from last Monday eliminated all of the null reference exceptions and many of the cross-threaded control calls, however, some are still sneaking through. Please see the stack trace below. This one seems to be related to the tab page component.

Also, Elegand Grid v3.6 CellButtons are still broken [in our application]: the grid does not emit CellButtonClick event when they are clicked, and when they are clicked, they get stuck in depressed state forever.

Hi!

I am dynamically adding controls to an Elegant.Ui.Panel and for making the controls outside the currently visible panel reachable I wanted to set the AutoScroll property. Unfortunately there is no such property.

Is there an other way to make the panel scrollable? Or how do i modify a ’normal’ panel to appear like an Elegant.Ui.Panel?

Regards,

Reini

thanks for your reply!

Hi,

The previous fix for calls to controls from wrong threads has successfully eliminated the invalid control call exception, however, it now produces a different exception, although with somewhat reduced frequency:

System.NullReferenceException occurred

We tried but failed to get cell buttons stuck in pressed state. We would appreciate if you provide a test project illustrating this issue.

One more note re: test code that was emailed: you can easily modify it to make 20 or 50 forms as opposed to 2, which will make it fairly close to our test case for control thread safety issues.

I have emailed the sample code to support@prof-uis.com ... this forum does not appear to have a way to attach files.

Thank you

Thank you again for the bug report. Please try the updated assemblies below which include the fixes for the ribbon and grid:

elegant-ui-67978.zip

Thank you for getting the update out quickly - it appears to have cured the null reference errors completely. I have not seen the other exceptions either, but I haven’t not run the test cases yet (tomorrow).

However, the CellButton click event is still not working on the grid v3.6, and the buttons still get stuck in the "pressed" state unless they somehow get refreshed (e.g. by disabling and turning them on again).The "regular" click event (inherited from Control) is working properly.

-A

And one more detail (in case T.M.I. has not occurred yet) - the cell buttons on elegant.grid v3.6 are not working properly (or rather at all most of the time), maybe that’s related. They press, get stuck in pressed state and fail to produce the expected CellButtonClick event, although that is partially rectifiable by using the Click event (which does come) and then calling GetRenderableFromPoint to get to the cell.

Is Elegant grid 3.6 some I ought to be even using? And if not, how do I make the old grid v1.3 look consistent with the new ribbon control?

I put a Elegant.Ui.Textbox as the last control into a Button Group and give it a minimum size of 25, so that i can see at least 3 digits, which have entered.

The TextBox overlaps the Control on the right side.
Set the Right Margin of the TextBox to 5.

This is immediately reflected in the Designer. But when i run it, it is still the same problem, as if the margin wouldn’t be set.

Please send the sample project to support@prof-uis.com.

Actually, a Button Group is supposed to contain only the following controls: Button, DropDown, SplitButton, and ToggleButton. Other controls may not work properly when they are put in a button group. Please send us a sample illustrating what you want to achieve.

Good day,

I need to insert a big picture in my screen tip. This will be some kind of help to user, when he moves the mouse over a button.

But it looks like the image size is limitet. Maximum what it allows me to show is 294*432 px.

 Is there a way to increase image size?

Thank you,

Gennadiy

OK, noted thank you.

Hi,

I have a multithreaded WinForms application, and there are multiple windows that run on their own message pump threads, that is, the window is created with code like this (start in NewTI):

    Public Class LaunchSettings
	    Public Self As FUIFaultTable
	    Public Title As String
    End Class
    Public Shared Function NewTI(Optional ByVal ATitle As String = "Console") As FUIFaultTable
	    Dim tthread As System.Threading.Thread = New System.Threading.Thread(New System.Threading.ParameterizedThreadStart(AddressOf TIStart))
	    Dim tsettings As New LaunchSettings
	    tsettings.Title = ATitle

	    tthread.Start(tsettings)
        Threading.Thread.Sleep(100)
	    SyncLock tsettings
		    Threading.Monitor.Wait(tsettings, 5000)
	    End SyncLock
	    NewTI = tsettings.Self
    End Function

    Private Shared Sub TIStart(ByVal ASettings As LaunchSettings)
	    Try
		    SyncLock ASettings
			    ASettings.Self = New FUIFaultTable
			    Threading.Monitor.Pulse(ASettings)
		    End SyncLock
            ASettings.Self.Text = ASettings.Title
		    Application.Run(ASettings.Self)
	    Catch ex As Exception
		    X.AssertSoft(False, "Unhandled Console error", Nothing, , ex)
	    End Try
    End Sub

In other words, the calling threads creates a new thread, which runs TIStart method, which runs the message pump in Application.Run, which exits only when the window is closed. There is also a simple notification to the calling thread that the window creation process in complete.

This code is compliant with Microsoft’s guidelines, and all the methods within this form are suitably protected against cross-threaded class by InvokeRequired() ... BeginInvoke() constructs, again as prescribed by MS.

Now to the problem: when Elegant.UI components (not necessarily the Ribbon, but for example a ToggleButton) are placed on this form, Application.Run throws an occasional exception with the following stack trace (always the same, always on the message pump thread, bounces out of Application.Run in the code snippet above):

   at System.Windows.Forms.Control.get_Handle()

   at System.Windows.Forms.Control.PointToClientInternal(Point p)

   at System.Windows.Forms.Control.PointToClient(Point p)

   at Elegant.Ui.Control.PointToClient(IControlInternal control, Point point)

   at Elegant.Ui.Control.OnPreviewMouseLeave(PreviewEventArgs e)

   at Elegant.Ui.Control.Elegant.Ui.IControlInternal.InvokePreviewMouseLeave(PreviewEventArgs e)

   at Elegant.Ui.Control.TunnelPreviewEvent(IControlInternal control, PreviewEventType eventType)

   at Elegant.Ui.Control.OnMouseMove(IControlInternal control, MouseEventArgs e)

   at Elegant.Ui.Control.OnMouseMove(MouseEventArgs e)

   at System.Windows.Forms.Control.WmMouseMove(Message& m)

   at System.Windows.Forms.Control.WndProc(Message& m)

   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)

   at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

   at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg)

This happens infrequently, but regularly enough, when mouse is moved over the controls. Frequency tends to be the highest when the window is being closed, for example if the "X" button is clicked and the mouse is accidentally moved over one of Elegant controls. Same for application shutdown, often times an exception will be thrown around the time when Form.Close is called. Overlapped windows increase the probability.

It appears that, somehow, a mouse move event from one message pump/window is passed onto another window (which runs on a different message pump thread), and then the recipient window tries to process it, and that’s when the form throws the exception. I know of no way that the form that is running on the same message pump can throw this exception.

And lastly, to answer the question as to why do we use multiple message pumps: we have a soft real-time application that regularly spikes the CPU. Lesser important GUIs are delegated to lower priority threads, that way the critical GUI elements do not get queued up behind long updates, such as table redraws.

Thank you in advance,

-Alex

Hi,

The fix is installed and was added to GAC with gacutil, but it has no effect. I am getting exactly the same errors with exactly the same frequency, stack traces and locatons.

It would seem to me that this is not a thread safety issue per se, this is an issue of routing the preview events from correct message pumps to correct windows, even though there may be only one thread involved.

Do you need any more information from my side?

Thanks,

-A

I have another essentially similar stack trace, slightly more complete, this one happened when my application was trying to quit and close the windows, and the notable bit information here is that the main application thread was in Sleep(1000), which it does while waiting for the multithreaded windows to shut down.

Thank you for reporting this issue. We made some changes to the code to make PreviewXXX events thread safe. Please check the following fix (you should add it to the GAC manually). If something is wrong, just let us know.

Is there any way to use the Elegant UI ContextMenu combinated with a System.Windows.Forms.NotifyIcon? I just used ContextMenu.ShowWithoutOwner(), but there’s no way to position the ContextMenu at a specified place?

Marc

We’ll probably add this functionality in a later release rather than in 3.7.

Thank you very much, that helped me out!

But, is there any way to implement this little future in the next update? This would make it a little easier to handle for something like that...

Mark

A ToggleButton has the Command Property, because it inherits from Button.

But the assigned Command is not executed.

I know that i can listen on the PressedChanged event, but being a Button it should also fire a Command

I have the ribbon in a UserControl, which is placed on the Main Form.

in my Main Form i have:
"protected override void OnKeyPress(KeyPressEventArgs e)" and "protected override void OnKeyDown(KeyEventArgs e)" to capture various key strokes.

Seems the ribbon is consuming all keypress and keydown events. I’m not getting them in my form anymore.

We think that the problem isn’t related to the ribbon. The keyboard events are only passed to the control which currently has a focus. When you put different controls onto the form they can gain focus and receive keyboard strokes instead. Try using ProcessDialogKeyMethod like it is shown below:

protected override bool ProcessDialogKey(Keys keyData)
{
   KeyEventArgs e = new KeyEventArgs(keyData);
   Keys myKey = e.KeyCode;
   return base.ProcessDialogKey(keyData);
}

Looks like setting the SelectedIndex = 0 does not work.

i have a ComboBox which i fill like that:

private List<Item> encoders = new List<Item>();

encoders.Add(new Item("MP3 Encoder", "mp3", ""));
encoders.Add(new Item("OGG Encoder", "ogg", ""));
encoders.Add(new Item("FLAC Encoder", "flac", ""));
encoders.Add(new Item("AAC Encoder", "m4a", ""));
encoders.Add(new Item("WMA Encoder", "wma", ""));
encoders.Add(new Item("WAV Encoder", "wav", ""));
encoders.Add(new Item("MusePack Encoder", "mpc", ""));
encoders.Add(new Item("WavPack Encoder", "wv", ""));
comboBoxRipEncoder.DisplayMember = "Name";
comboBoxRipEncoder.ValueMember = "Value";
comboBoxRipEncoder.DataSource = encoders;

comboBoxRipEncoder.SelectedIndex = 0; // This does not select the first entry in my list: "MP3 Encoder"
comboBoxRipEncoder.SelectedIndex = 1; // This selects correctly the second item in my list "OGG Encoder"


public class Item
{
public string Name;
public string Value;
public string ToolTip;

public Item(string name, string value, string tooltip)
{
Name = name;
Value = value;
ToolTip = tooltip;
}

public override string ToString()
{
// Generates the text shown in the combo box
return Name;
}
}

Thank you for reporting the bug. We have already fixed it so the fix will be available in version 3.7. There are two options to workaround this bug right now:

1. We provide you with the updated Elegant.Ui.Common assembly which has the bug fix. You will have to install it into the GAC manually.
2. Tell us where exactly you initialize the combo box so we can suggest a workaround.

I’m adding a Textbox with a label to a Group and want to place a Button (SmallImage only set for Informativness) just behind it.

e.g. Output Folder: ______________________ ...

The 3 dots indicate should open a FolderBrowserDialog to select the Output Folder.

The button is always placed below the TextBox.

is there a way to achieve this?

In the designer, select TextBox control and, in the properties window, set the FlowBreak property to true.

I’m placing a multi-line textbox inside a ribbon group. It seems ok in designer, but at runtime it simple desapearings. May it be a bug?

When I collpase the ribbon, how do I Adjust the content of the form as the samples shown.

All you need is to put all your content on the panel with Dock property set to DockStyle.Fill.
