[Solved] Cross Field Validation?

[Panya Thanyaprasertkul]

Hi there,

I'm just evaluating Rad Controls for ASP.NET

I have some question about validation model in RadGrid.

Does it offer something richer than ASP.NET style validation?

I think ASP.NET validation does not answer the real-life applcation.

You just don't validate that this field should less than this or that.

In real application we sometimes need to validate data cross fields

and under some certain conditions.

I see in the Validation section of RadGrid in Demo and found that

you just use System.Web.UI.WebControls.ServerValidateEventArgs class

which is too lame to me. Is there another validation model to use than that.

Or we just need to code a sequence of IF THEN ELSEIF to validate data item

on Insert, Update, DeleteCommand?

Thanks

Panya

Hi Panya,

Basically, there is no other form/model for validation. Especially for complex scenarios with cross field validation. With the grid control, you have two options.
You can either attach to the ItemCommand event handler of the control, and intercept the new values as the user triggers the commands. Or, you can add validators to the grid edit form. This can be done either declaratively, or dynamically.
These approaches cover all possible scenarios, and I hope one of them is suitable for you.

All the best,
