Question

I want to redirect to the another page in the same project and fire click event automatically. I am able to redirect to another page, but need help on how to fire the event automatically. The class from where i am redirecting is called Testing and the class to which i redirect isTabTest. My code in theTesting` class is:

  protected void LinkButton2_Click(object sender, EventArgs e)
  {
      Response.Redirect("TabTest.aspx");
  }

You cannot directly fire the event on redirection.

A solution is to add a query string parameter to the redirect:

Response.Redirect("TabTest.aspx?ShowChart=true");

In the Page_Load event of TabTest.aspx, add the following code:

if(Request.QueryString["ShowChart"] != null 
  && Request.QueryString["ShowChart"] == "true"))
{
    // Call the click event handler for the button that shows the chart. Passing
    // `null, null` assumes that you don't use the sender or eventargs parameters
    // in the event handler.
    ShowChart_Click(null, null);
}
