Combobox in AutoGeneratedColumn

[Glenn]

Hello,

In the datasouce I'm using, there is a boolean field I'm showing in an autogenerated column. The problem is, though, that in the database this is a nullable field, so the CheckboxColumn the Grid automatically generates isn't really useful. Is there anyway to have the boolean show in a combobox (which becomes interactive when activating in-line editing), rather than a checkbox, with values for null, true and false?

Any help or directions would be appreciated.

Sincerely,
Glenn

Hello Glenn,

You can try the following code snippet to add new control instead of CheckBox.
C#:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
       {
           GridEditFormItem item = (GridEditFormItem)e.Item;
           TableCell cell = item["BoolVal"] ;
           cell.Controls[0].Visible = false;
           RadComboBox cb1 = new RadComboBox();
           cb1.ID = "Radcombo1";
          //Bind the combo
           cell.Controls.Add(cb1);
       }
   }

Thanks,
Princy.
