To prevent the user from resizing the rows or columns of a datagrid you need to create a new datagrid. To create a new grid create a class that inherits from datagrid. To prevent the resize prevent the OnMouseDown and OnMouseMove messages from firing when the user is at the resize spot.
Be aware this is a Tip for a WindowsForms DataGrid not a DataGridView
Public Class NoResizeGrid
Inherits DataGrid
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 Or hti.Type = DataGrid.HitTestType.RowResize Then
Return 'no baseclass call
End If
MyBase.OnMouseDown(e)
End Sub
Public Sub New()
End Sub
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 Or hti.Type = DataGrid.HitTestType.RowResize Then
Return 'no baseclass call
End If
MyBase.OnMouseMove(e)
End Sub
End Class
