Preventing Column Width Changes in a datagrid 1

[Elena]

Anyone know how to prevent column width changes in a datagrid? I know there is a WidthChanged event for the ColumnStyles but I don't know how to use it. When I try to make a subroutine to handle it, it only gives me the child objects of the form. I can't even get to the columnstyles.

Thanks,
Elena

You can achieve this by overriding OnMouseMove event and not calling the baseclass if the point is on the columnsizing border.


Public Class MyDataGrid

Inherits DataGrid

Protected Overrides Sub OnMouseMove(ByVal e As System.Windows.Forms.MouseEventArgs)

Dim hti As DataGrid.HitTestInfo = Me.HitTest(New Point(e.X,e.Y))

If hti.Type = DataGrid.HitTestType.ColumnResize Then

Return 'no baseclass call

End If

MyBase.OnMouseMove(e)

End Sub

End Class

you'll have to use the above code in override of OnMouseDown event.

Protected Overrides Sub OnMouseDown(ByVal e As System.Windows.Forms.MouseEventArgs)

Dim hti As DataGrid.HitTestInfo = Me.HitTest(New Point(e.X,e.Y))

If hti.Type = DataGrid.HitTestType.ColumnResize Then

Return 'no baseclass call

End If

MyBase.OnMouseDown(e)

End Sub
