SingleClick and validation

[moegal]

I have a form with a RadButton set to use the new SingleClick and a RadDatePicker with a RequiredFieldValidator.

The button stays depressed after clicking if the  RadDatePicker is empty.

Any ideas?

Hey moegal,

You can handle the OnClientClicking event of the RadButton and check if validation passed or not. If it doesn't you cancel the click, thus preventing the single click functionality from kicking in.

Javascript:

function OnClientClicking(sender, args) {
            // make sure page is valid
            if (!Page_IsValid) {
                args.set_cancel(true);
            }
        }

I hope that helps.

Kevin,

Thanks. That works!

I had already tried it but I did so incorrectly (I was using the wrong event handler. "OnClientCheckedChanging" for the type of button)

A client-side validation is pretty common scenario, and telerik:Button should be smart enough not to disable itself if no postback/callback occurred. Would it be reasonable to add your workaround into Button logic?

Hi Michael,

This scenario is handled by RadButton, however there is a bug in the last version of Telerik UI for ASP.NET - http://feedback.telerik.com/Project/108/Feedback/Details/131636-fix-button-single-click-gets-disabled-permanently-if-required-field-validator-er

The problem is already handled and the fix will be available in the upcoming service pack.
