Using Predefined Dialogs with Codebehind

[John Esposito]

Hello,

I can easily display a radalert dialog from my C# codebehind with the following line of code:

RadAjaxManager1.ResponseScripts.Add(@"radalert('Record already exists.', 225, 110);");

I assumed that working with the confirm and prompt dialogs would be similar, so I tried the following:

RadAjaxManager1.ResponseScripts.Add(@"radprompt('Are you sure?', promptCallBackFn;");

But I cannot get the radprompt to even display (at this point I am only concerned with displaying the prompt). Am I wrong in assuming that I can treat these dialogs identically?

Thanks,

I noticed in your code that you did not add the closing bracket for the radprompt call. I'm assuming that's the reason it's not showing.

Thank you for catching that robertw. I accidentally deleted it after removing all optional arguments for the dialog. Instead of nothing happening when I try to display the dialog I now get an "error on page" message in the browser's message area. The search continues.

It's odd because in my testing I'm only replacing the radalert call, which works fine, with the radprompt call. If the two should be handled differently, I can't find any reference to it in the documentation. (To anticipate another question: I do have a promptCallBackFn properly defined in my code).

Does it work for radbutton onClick event? I tried and not able to see the expected result..

Hi Cheekl,

You need to specify the correct syntax of the function as shown in the following articles:

http://www.telerik.com/help/aspnet-ajax/window-dialogs-confirm.html
http://www.telerik.com/help/aspnet-ajax/window-dialogs-prompt.html

On the other hand, I would suggest that you use the server-side methods to call these dialogs, which are available since Q1 2011. You can see them in action in the following online demo as well: http://demos.telerik.com/aspnet-ajax/window/examples/browserdialogboxes/defaultcs.aspx.
