DataGrid: Prevent Row And Column Resize

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.
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
