    Hello Remya,

    The problem is most probably caused by parts of your code that are not displayed in the provided code sample, as the described behavior does not occur by using only the RadButton. The exact cause cannot be determined by the presented error message, since it could be received in various scenarios.

    Please open a support ticket and send a simple, runnable page that isolates the reported problem so that we can examine it locally and suggest a concrete solution. A reliable steps for reproducing the issue will also be useful for detecting its cause.

    All the best,
    the Telerik team
