Try this,

Set EventValidation to false for the page and also override VerifyRenderingInServerForm in code behind,

public override void VerifyRenderingInServerForm(Control control)
{
 
}

hey just set viewstate false

//Turn off the view state
this.EnableViewState = False;
//Remove the charset from the Content-Type header
Response.Charset = String.Empty;

and
EnableEventValidation="false"

You posted a question as an solution which was probably not want you intended. If you have a question or comment about the original question use the "Have a Question or Comment?" option beneath the question. On the other hand if you have a similar problem your best option is to create your own new question, for this use the "Ask a Question" button at the top of the page. Using an solution like this will give the people the impression that the question has been answered and perhaps not look at it, causing the OP not to get an answer to his/her question. Please move the content of this solution to the appropriate section and remove the solution. Thank you.
