custom validation

[Albert Shenker]

How do I use a customValidator With RadGrdi to validate ALL of the editable fields in a grid when in-line editing is used. In such a case, I don't set ControlToValidate in the CustomValidator, so in my ServerValidate Event, I don't know how to obtain the values being updated. The example shown in

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

only pertains to validating a single field.

Private Sub custVal_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles custVal.ServerValidate
            args.IsValid = ValidatedConfiguration()
        End Sub

Private Sub ValidatedConfiguration()
' How do I access the updated values here?
End Function

Hi Albert,

To be able to use the same validator for any and all editable items, you would best define it outside the grid. Then on its ServerValidate event, loop through the grid edited items (use EditItems or EditIndexes collection) and validate the input by accessing the editors for the desired fields and checking their value for instance.

Let me know if this helps or I missed something out.

All the best,
