How do I implement validation on UserControl Edit form?

[Henrik]

I have to make some checks through WebServices before I save/update. Can I stop my buttons from doing any Insert/Update action? And ofc leave the edit-form open if validation fails.

Hello Henrik,

You can use the server-side validation mechanism to achieve the desired scenario.

Refer the following demo for more on server-side validation of the RadGrid edit form.

Hi!

Yeah I can usew that but I need to do some custom things so I need to manually do it if possible.

I noticed that If I have a blank CommandName on button no action is taken ... But if I set CommandName="PerformInsert" in code in my button things happen.

Only problem is when I do like this DataItem is lost after postback so I have to preserve DataItem in ViewState manually

Not sure if this is the way to do it though ..
