imagebutton

Question

i am using imagebutton within a datalist but when i click on imagebutton error is showing as-

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

can anyone help me please...

In your page set EnableEventValidation =false on top of @page directive @ Page Language =C# AutoEventWireup =true CodeFile =Page.aspx.cs Inherits =Page EnableEventValidation =false %> and bind datalist in Postback check if(!Page.ispostback) { // code to bind datalist }
