Hi guys
I am working on Gridview and i wanna do DELETE Operation on my Gridview row..but i click on grid view delete image button it throws exception like this..

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.

code..

C#

protected void gdProducts_RowDeleting(object sender, GridViewDeleteEventArgs e)
       {
           try
           {
               objBusinessUI.ProductID = Int32.Parse(gdProducts.DataKeys[e.RowIndex].Value.ToString());
               objBusinessUI.UpdatedBy = "Admin";
               objBusinessUI.UpdatedOn = DateTime.Now;
               string StrMsg = objDataUI.DeleteProduct(objBusinessUI);
               if (StrMsg=="SUCCESS")
               {

               }
               else
               {

Solution 1

Have you registered the event properly on loading of the page ?

ASP.NET

<pre lang="xml"><script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        ScriptManager1.RegisterAsyncPostBackControl(Button1);
    }
</script>

Solution 2

Try using GridViews

HTML

RowCommand

event instead of RowDeleting
and change the CommandName property of ImageButton from "Delete" to something different e.g. DeleteRecord

Example of gridview rowcommand on Button Click [^]
