Grid Insert/Edit fails validation, cancel tab change

[THOMAS]

We have a RadTabStrip controlling a RadMultiPage.  In three of the RadPageViews we have a RadGrid.  The EditForm of these RadGrids contains ASP RequiredFieldValidators.  The problem occurs when the RequiredFieldValidators are not satisfied, the user changes tabs, and tries to navigate away from the page which calls Page.Validate().  The validation errors do not stop RadTab change and are no longer visible.  I'm looking for a way to stop that RadTab navigation from occurring when there are ASP.NET Validation errors.  (2010.3.1109.35)  Thank you.

Hello Thomas,

You can easily achieve this by setthing RadTabstrip  CausesValidation property to "true".

Thanks,
Shinu.

CausesValidation is already set to true.

Hello Thomas,

Another option might be to handle the RadTabStrip OnClientTabSelecting event and check there whether the page has validation errors and cancel the event if needed.

I added the handler below for the OnClientTabSelecting event which did the trick.

function MatterTabSelecting(sender, eventArgs) {
    if (typeof (Page_ClientValidate) == 'function') {
        Page_ClientValidate();
        if (!Page_IsValid)
            eventArgs.set_cancel(true);
    }

    return false;
}
