[Solved] OnClientClicked Firing Before Validation?

[Matt]

I have a radbutton that works with a validation group to check a drop down before showing a confirmation popup. I have found the OnClientClicked is firing before the validation is complete. I'm wondering if this could be related to the current issue with the radbutton and the Q1 2013 release. I am currently running last night's internal build.

<telerik:RadScriptBlock runat="server">
    <script type="text/javascript">
        function VALIDATEME(sender, args) {
            args.set_cancel(!window.confirm('Validate?'));
        }
    </script>
</telerik:RadScriptBlock>

<telerik:RadButton ID="SaveButton" runat="server" CausesValidation="true" CommandName="Save"
         Text="Save" OnClientClicked="VALIDATEME" ValidationGroup="Save" />

<telerik:RadComboBox ID="combo" runat="server" />

<asp:RequiredFieldValidator ID="validator" runat="server" ControlToValidate="combo" ValidationGroup="Save"
         InitialValue="" ErrorMessage="Error!" Text="*" />

<asp:ValidationSummary ID="ValidationSummary" runat="server" ValidationGroup="Save" />

Hi Matt,

The client-side events - OnClientClicked and OnClientClicking are triggered after the execution of the validation, no matter whether the validation is successful or not. I have recorded a short video test here. This behavior is observed in the older versions of RadControls as well.

Note also that in your code snippet you are using OnClientClicked event which cannot be canceled because it is fired just before the page is submitted. OnClientClicking event, however, is triggered when the button is clicked, immediately after the mouse button is released and it can be canceled by set_cancel(true) method.
