Hello I have create an application for food ordering, but it's giving me error like

"Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed."

I have use ajax modal popup to save in the cart and it gives error only on server not on localhost and that too after adding 6-7 items to the cart.

I have search on almost every blog and have try many ways but couldn't solve the issue.

Can anyone help to solve this?

Hi hardik5165,

Try to Add PostBackTrigger in UpdatePanel with the ControlID

<Triggers>
    <asp:PostBackTrigger ControlID="PostbackButtonName" />
</Triggers>

Or add below and check.

protected void Page_Load(object sender, EventArgs e) 
{
  ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
  scriptManager.RegisterPostBackControl(PostBackButtonName);
}
