hi,
i got following problem:  if i click on linkbutton the radconfirm popups, but it closes immediatly and then the server code will be executed without confirmation.

<asp:LinkButton ID="btnDelete" Visible="false" runat="server" CausesValidation="False" 
                    CssClass="DeleteButton" OnClick="btnDelete_Click" OnClientClick="return radconfirm('Möchten Sie wirklich löschen')" 
                    Text="Löschen"></asp:LinkButton> 

Any idea, why it closes immediatly?

Hi Chp,

This behavior is the expected one, because when you click on the LinkButton a postback is triggered and the page is refreshed.
You can avoid the postback by using the following code :

<asp:LinkButton ID="btnDelete" Visible="false" runat="server" CausesValidation="False" 
    CssClass="DeleteButton" OnClick="btnDelete_Click" OnClientClick="radconfirm('Möchten Sie wirklich löschen'); return false;" 
    Text="Löschen"
</asp:LinkButton>

Hi Fiko,

With your code, the confirm stays for the user input, but will not trigger the link button event if OK is clicked.

Hi Sajeev,

This behavior is expected and it is caused by the "return false" statement that cancels the event.
However, you could use this approach in order to achieve the desired behavior. For your convenience I have reworked the ASP.NET2.0 example in order to use the ASP.NET AJAX version of the controls. Could you please check it and let me know whether it fits your requirement?


Kind regards,

Hi, following the example code above, and also when trying the similar code here: http://demos.telerik.com/aspnet-ajax/window/examples/browserdialogboxes/defaultcs.aspx ("Confirm postback with radconfirm") I encounter a major problem.

After the confirm-window pops up, pressing "Cancel" works fine. The popup disappears and no postback is done.

But if I press "OK" nothing happens. The confirm-window either stays there or reopens quickly (might be I see a flicker). I'm using Internet Explorer 7.

Has there perhaps been any updates to this control lately making the example-code invalid? Or is it some other error?

Hello Hans,

I tried to reproduce the problem on our live demo but everything worked as expected - we haven't made any changes in this logic and you are the first to report such issue. Could you please try resetting your browser's settings and try again?
