How to prevent row header text from being deleted?

[Joy Ni]

I am new to this Grid control. It seems I can highlight a row and hit delete. Then the row header text I just customized will be deleted. How can I prevent this from happenning? User should be able to delete the cell text but not the header text.

Thanks.

After setting the Header text, also set the cell to be ReadOnly.

 Me.GridControl1(2, 0).Text = "sample"
 Me.GridControl1(2, 0).ReadOnly = True

I tried this. It still allowed deletion of the header text.

Setting ReadOnly works in the 1.6 RC1 release which you can download from this link.

In 1.5.2.0, if you want to prevent this you can catch the ClearingCells event, and only clear the non-header cells.

    Private Sub GridControl1_ClearingCells(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.GridClearingCellsEventArgs) Handles GridControl1.ClearingCells
        If e.RangeList.AnyRangeIntersects(GridRangeInfo.Col(0)) Then
            Dim range, range1 As GridRangeInfo
            For Each range In e.RangeList
                range1 = range.ExpandRange(1, 1, GridControl1.RowCount, GridControl1.ColCount)
                Me.GridControl1.ClearCells(range1, True)
            Next
            e.Handled = True
        End If
    End Sub
