WebUserControl CustomValidator

[Scott Marx]

I have a RadGrid with the EditFormSettings set to WebUserControl. Within the WebUserControl I have a CustomValidator, when I run the update command from the WebUserControl page the CustomValidator is run, but does not stop the page from processing. I am checking for Page.IsValid on my RadGrid_ItemCommand.

Hello Scott,

Check the following help documentation which explains about validation.
Validation

-Shinu.

[Scott Marx]

Not sure why you sent me there... My code already followed the examples there. The problem is passing the failed validation to the page from the WebUserControl.


Opps... My bad. I see I needed to change editcontentCustomValidator.IsValid to args.IsValid.
