Hi,
I having the following issue. I have a main form (MDI Parent) set up with the Elegant Ribbon and three MDI Children. On the Elegant Ribbon, I have one button to clear any contents of the TextBox component. On one MDI Child, I have a Elegant Ribbon TextBox component. When I click the button, it does nothing. The content in the TextBox still remains.
Now, I wanted to check if the MDI Child is active or not. But this does not work either.
Private Sub btnNew_Click(sender As Object, e As EventArgs) Handles btnNew.Click Dim NewMDIChild As New frmCLA() Dim activeChild As Form = Me.ActiveMdiChild
If (Not activechild Is Nothing) Then MsgBox("No active MDI Child", MsgBoxStyle.Exclamation) Else MsgBox("Active MDI Child: " & NewMDIChild.Name, MsgBoxStyle.Information) End If End Sub
The source code shows whether or not the MDI Child is active and it gives constantly "No active MDI Child".
What am I doing wrong or missing?
Roland
