Hello,
I want to call WebMethod (HelloWorld) from Javascript, when I click on Telerik Button, which will display alert message box.
But I am always getting error as Webmethod Failed.
Am I missing anything?
It is working when use ASP.NET Button control and ScriptManager.
If you can give me any example, it would be helpful.
Thanks in advance.

Hello Prajakta,
You need to pass the name of the function to the RadControls client event and not the full javascript as with the asp controls:
JavaScript:
I hope this will prove helpful. Please give it a try and let me know about the result.
