Greetings,

Elegant Grid 3.7 Unbound Grid appears to be reliably producing exceptions under the following circumstances:

- scrolling is in progress (mouse button down and moving)

- timer expires to rebuild the table contents, which removes all rows and adds all new ones (same thread as the message pump)

Stack trace:

System.ArgumentOutOfRangeException occurred

  Message=Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

  ParamName=index

  InnerException:

I am not sure if this makes any difference, but the message loop for the windows is NOT running on main application thread.

I tried a few workarounds, but none are too effective besides tracking scrollbar mouse events and that’s not as easy as may first appear. Suggestions?

-A

i create this class

 TextCellCustomEditor : TextBox, ICellEditor
{
   base.MaxLength = 20;
  //some code
}

and after i create column

 TextCellStyle myTextCell = new TextCellStyle();
 myTextCell.CustomEditorType = typeof(TextCellCustomEditor);
 myTextCell.TextAlignment = ContentAlignment.MiddleLeft;

 myColumns[0] = new Column();
 myColumns[0].DataPropertyName = "1";
 myColumns[0].Visible = true;
 myColumns[0].CellType = typeof(TextCell);
 myColumns[0].CellStyles.AddRange(new Elegant.Ui.Grid.CellStyle[] { myTextCell });
 myColumns[0].HeaderText = "Text cells";

it’s work ok but i need change  MaxLength programmatically. How i can do it?

How i can change this variable when i create column and how i can change this variable in runtime?

MaxLenght is not the width of column but total of characters that it can import the user. For TextBox.MaxLenght = the 10 user can put only 10 characters in the field. This I want to achieve.

Each time your custom editor is activated you can set MaxLength to a specified value.

Please use the Column.Width property. Alternatively you can use the Column.MinimumWidth to make sure that column won’t become smaller in auto-size mode.

i want that each column to have its own maxlength. i need to initialize the maxlength for each column during its creation.... or to change the maxlength in runtime.

For example, i want to enter the length in the textbox (not in the grid)  and after pressing enter i want to set the length for the sellected column, i didnt find how to make it.

I want to extend class TextCell and create class inherrited

 class MyTextCell:TextCell

    {

        public MyTextCell(GridControlBase gridControl, Column column)

            : base(gridControl, column)

        {

        }

        protected override void OnKeyDown(object sender, System.Windows.Forms.KeyEventArgs e)

        {

           //some code

        }

    }

But when i write this code

cellsText[k] = (MyTextCell)dr[k].AddNewCell(typeof(MyTextCell), unboundGridControl1.Columns[0]);

mistake comes out  "Constructor on type ’CSUST.Data.MyTextCell’ not found.."

How can i create correcltly the inherrited of this class?

I found how I make. pleasant

I create inherited class with two constructors. There are no mistakes now

public class MyCell : TextCell
    {
		 public MyCell(GridControlBase gridControl, Column column)
		    : base(gridControl, column)
	    {

	    }

		 public MyCell(Column column, GridControlBase gridControl)
		    : this(gridControl, column)
	    {

	    }
	    public TextCellStyle Style 
	    { 
		    get
		    {
			    return this.Style;
		    }
	    }
        protected override void OnKeyDown(object sender, KeyEventArgs e)
	    {
		   // some code
		    base.OnKeyDown(sender, e);
	    }
}

How shall i make so as the verticalscrollbar when appears in the grid not to be above the last column but next to it on the right of the column. see how it looks in my grid the last column (see the picture picasaweb.google.com/alexandros.pg#)

I am thinking of purchasing Elegant Grid but a little concerned that there hasnt been a new release since Nov 2006

Is there a new build coming? I would need it to support VS 2010 and .NET

Thanks

BoundGrid control.

how can i know above which cell is the mouse without pressing the button of the mouse? just when i move the mouse over the grid...

I have stable exception at use of function EnsureVisibleVertically() for scroll after addition new row to end of the grid.

Test project (VS2010) I has sent to you the day before yesterday, but has not received the answer.

Exception text: "Index was out of range. Must be non-negative and less than the size of the collection."

Thank you for the bug report. Please download a fixed version of Elegant Grid below:

I am currently evaluating Elegant grid and am having a bit of difficulty implementing a column with a populated combo box. Could you provide a simple example of using a combobox in a column?

Would you please tell me what the latest version is? A quick look at the version history says that this product has been dead since just after beta. Is this factual or is the web page not kept up? I found a link to a dll on the forum that is stated as the latest version. Downloading the file reveals a dll that says it is now version 3.5.0.0. This seems like a pretty big leap from 1.3->3.5?! Could you please explain what you actually have here?

Yes, officially we have not yet released any new version since v.1.3. But internally we have refactored the grid in terms of compatibility with Elegant Ribbon and themes. That is why its current non-official version is 3.5, the same as that of Elegant Ribbon. The grid has also been supported all the time since it was released. We plan to release a new version of Elegant Grid after releasing Elegant Ribbon v.3.6. The latter is scheduled for release this week.

Could you or would you care elaborate on what added features are planned for version 3.6. So far my experience is that I like to basic object model dislike the terribly sparse help file and feel some rather important features appear to not be available (or maybe  simply not documented) so at this point I am stuck looking for a reason to make the purchase.

Could you let us know which version of grid you are using?

Version 1.3 for .Net 2

That didn’t post right. It should have said

Column.MappingDataSource Property

Gets or sets the mapping data source value for the column

You can give me source code from sample "Simple Grids"?

I want only opens my combo box cell. I do not want can the user change the text in the cell. How I make him?

if i set  this.comboBoxCellStyle3.DropDownStyle = ((Elegant.Ui.Grid.ComboBoxStyle)(Elegant.Ui.Grid.ComboBoxStyle.DropDownList)); it is not  working?

if i set  this.comboBoxCellStyle3.AllowEdit = false; i cannot open my combo box list...

Hi.

Αfterwards that I step the button the program asks if I want to close the form. Before I step are stored the elements that I have put in cells the text that is in selected cell automatically it changes or in the previous text if existed something in or cleared if cell they were void. What it should I make in this case?<qtlend></qtlend>

<qtlbar style="padding: 0pt; display: inline; text-align: left; line-height: 100%; background-color: rgb(236, 236, 236); -moz-border-radius-topleft: 3px; -moz-border-radius-topright: 3px; -moz-border-radius-bottomright: 3px; -moz-border-radius-bottomleft: 3px; cursor: pointer; z-index: 999; left: 64px; top: 72px;" dir="ltr" id="qtlbar"><iframe style="border: 1px solid rgb(236, 236, 236); display: none; background-color: white;" src="" id="qtlframe"></iframe></qtlbar>

How i can set my combo box cell not editable? (user cannot change text in my combo box cell).I set style for my combo box cell DropDownStyle = DropDownList. But, it’s not work...(((. If i set Editable=false for my column i cannot open my combo box cell.

Thank’s. i try this code

if (boundGridControl1.EditingCell != null)
                boundGridControl1.EditingCell.CommitEdit(true);

and now all work ok.

for combo box element I could not accomplish in order to it does not become edit text his. if you can give me a example?

Hi. When I type some text in my cell and after press [X] button for close form the text from the current cell automatically lose. what I can do in this situation?

Please add the following code to your FormClosing event handler:

if (boundGridControl1.EditingCell != null)
                boundGridControl1.EditingCell.CommitEdit(true);

1. if my combo box cell dropped down how i can know this programmatically? you can show me one example?
2. I could not make so my combo box cell becomes dropped down and at the same time the user be possible to change text. you can show me how i can do it?

1. It is not supported at the moment. We plan to add this functionality in the future.
2. Please use the updated version that we sent to you by email today.

I have programs only on one drive(C\:) & data on other drives.  ProfUIS is on  the programs drive.  I had to reformat it.  When I ran after projects that proviously worked ok now looked for ProfUIS288u.dll.  I copied the dll into the project folder but it didn’t make any diff.

I created a new MFC MDI app proj with all defaults except for adding an odbc db which worked ok.  That is

I added  #include <Prof-UIS.h> in  to the stdafx.h   I expect the problem is in the way that I reinstall ProfUIS 2.88.

Any clues?

Thanks
