Selection Changed event in Grid Cell Combo

[Jitendra]

Hi,
In my Grid,I have a Column of cell type "ComboBox".I want to make next Column ReadOnly/ Read-write based on the SelectedValue of the Combo box.How to do that.How to register the SelectionChangeCommitted event for this Combo in the Grid.And also When I am trying to get CellValue of this combo box column its always giving null even there is an item selected in the Combo. Please help.

Regards,
Jitendra.

There are a couple of ways you can do this depending upon whether you are using a GridControl or GridDataBoundGrid.

Here is a way that should work for either case. Subscribe to either gridControl1.QueryCellInfo or gridDataBoundGrid1.Model.QueryCellInfo. In your handler, if e.RowIndex > 0 and e.ColIndex points to the column that you might want to be readonly, then get the value of the test cell using grid[e.RowIndex, testCellColIndex].CellValue. Then depending on this test value, if you want to make the cell ReadOnly, set e.Style.ReadOnly = true. Here is a KB link discussing this idea. http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=95&catId=11
