[Solved] Required Field Validator on GridTextBoxColumnEditor

[Josh Winkler]

I have seen the examples for putting a required field validator on textboxes but the same convention does not work for the dropdowns. Here is what we have and we need to get this to work with the dropdown. There isnt a DropDownControl for us to use this with a dropdown as there is with a textbox.

Dim

 

Service As GridTextBoxColumnEditor = CType(item.EditManager.GetColumnEditor("Service"), GridTextBoxColumnEditor)

 

 

Dim YCell As TableCell = CType(Service.TextBoxControl.Parent, TableCell)

 

 

Dim rfv1 As New RequiredFieldValidator()

 

Service.TextBoxControl.ID =

"Service"

 

rfv1.ControlToValidate = Service.TextBoxControl.ID

rfv1.ErrorMessage =

"Please select a Service"

 

YCell.Controls.Add(rfv1)

Please let us know what the solution would be for this scenario to change the code above from a textbox to a dropdown. Thanks.

Hello Josh,

The best option in this case would be to reference the edit form, and add the validator directly. More information on this option is available in the following article:

http://www.telerik.com/help/aspnet-ajax/grdaccessingcellsandrows.html

You can couple the code in the first section, with code which checks if the item is in edit mode (&& e.Item.IsInEditMode).
 I hope this gets you started properly.

Best wishes,
