Button On Click event not firing

the on click event works in other pages though.

here's the header of the page i'm trying to get it to work:

<%@ Page Title="Report" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeFile="Report.aspx.cs" Inherits="Report" %>

    <%@ PreviousPageType VirtualPath="~/Default.aspx">

and the code behind:

protected void Page_Load(object sender, EventArgs e)
    {
        if (PreviousPage == null)
        {
            Res开发者_JAVA百科ponse.Redirect("~/Default.aspx");
        }
            // code..

when i click on it, it just redirects me to the PreviousPage. it also doesn't stop even when it has a breakpoint inside.

protected void export_Click(object sender, EventArgs e)
    {
           //code
    }

In your Page Load, try using:

if(!Page.IsPostBack)
{
      if (PreviousPage == null)
      {
          Response.Redirect("~/Default.aspx");
      }

}

My answer is more about hints.
Have you created in code Behind method to handle the click?

Something like ButtonConfirm_Click(EventArgs e...
