An unhandled exception of type 'System.StackOverflowException' in System.Windows.Forms.dll

What I have tried:

    Ch_hello.Width = ColumnHeader1.Width + ColumnHeader2.Width
    Ch_world.Width = ColumnHeader3.Width + ColumnHeader4.Width
    Ch_hi.Width = ColumnHeader5.Width + ColumnHeader6.Width + ColumnHeader7.Width
End Sub
Private Sub ListView2_ColumnWidthChanged(sender As Object, e As ColumnWidthChangedEventArgs) Handles ListView2.ColumnWidthChanged
     ColumnHeader1.Width = Ch_hello.Width / 2
     ColumnHeader2.Width = Ch_hello.Width / 2
     ColumnHeader3.Width = Ch_World.Width / 2
     ColumnHeader4.Width = Ch_World.Width / 2
     ColumnHeader5.Width = Ch_hi.Width / 3
     ColumnHeader6.Width = Ch_hi.Width / 3
     ColumnHeader7.Width = Ch_hi.Width / 3

Probably because you are changing the column width which triggers the event that changes the column width which triggers the event until you overflow the stack.

Sorry for my bad english! yes i think too but i can't find any solution :(

2 solutions

Solution 1

Try either method:

VB

Private ListView1Changing as Boolean = false
Private Sub ListView1_ColumnWidthChanged(sender As Object, e As ColumnWidthChangedEventArgs) Handles ListView1.ColumnWidthChanged
if ListView1Changing = false Then
   ListView1Changing = true
    Ch_hello.Width = ColumnHeader1.Width + ColumnHeader2.Width
    Ch_world.Width = ColumnHeader3.Width + ColumnHeader4.Width
    Ch_hi.Width = ColumnHeader5.Width + ColumnHeader6.Width + ColumnHeader7.Width
   ListView1Changing = false
Endif
End Sub

Or

VB

Private Sub ListView1_ColumnWidthChanged(sender As Object, e As ColumnWidthChangedEventArgs) Handles ListView1.ColumnWidthChanged

RemoveHandler ListView1, AddressOf ListView1_ColumnWidthChanged

    Ch_hello.Width = ColumnHeader1.Width + ColumnHeader2.Width
    Ch_world.Width = ColumnHeader3.Width + ColumnHeader4.Width
    Ch_hi.Width = ColumnHeader5.Width + ColumnHeader6.Width + ColumnHeader7.Width

AddHandler ListView1, AddressOf ListView1_ColumnWidthChanged

End Sub

Thanks Michael, i tried, both the codes are working only for the first column of listview2 and the first two of listview1.

The handler works for any columnwidth change on the listview, put a break in the event handler and use the debugger to see what is happening.

For instance, looking at your logic, if you alter the column width of LV2's columnheader4 the event handler would reset it to header1's width/2, so you would never see a change.

Solved like this thank you Michael.

VB

Private ListView2Changing As Boolean = False
Private ListView1Changing As Boolean = False

Private Sub ListView2_ColumnWidthChanged(sender As Object, e As ColumnWidthChangedEventArgs) Handles ListView2.ColumnWidthChanged
    If ListView1Changing = False Then
        ListView2Changing = True
        ColumnHeader4.Width = ColumnHeader1.Width / 2
        ColumnHeader5.Width = ColumnHeader1.Width / 2
        ColumnHeader6.Width = ColumnHeader2.Width / 2
        ColumnHeader7.Width = ColumnHeader2.Width / 2
        ColumnHeader8.Width = ColumnHeader3.Width / 3
        ColumnHeader9.Width = ColumnHeader3.Width / 3
        ColumnHeader10.Width = ColumnHeader3.Width / 3
        ListView2Changing = False
    End If
End Sub
Private Sub ListView1_ColumnWidthChanged(sender As Object, e As ColumnWidthChangedEventArgs) Handles ListView1.ColumnWidthChanged
    If ListView2Changing = False Then
        ListView1Changing = True
        ColumnHeader1.Width = ColumnHeader4.Width + ColumnHeader5.Width
        ColumnHeader2.Width = ColumnHeader6.Width + ColumnHeader7.Width
        ColumnHeader3.Width = ColumnHeader8.Width + ColumnHeader9.Width + ColumnHeader10.Width
        ListView1Changing = False
    End If
End Sub
