How to wrap an aspx.cs code page in an error handler.

A customer is experiencing an exception error when selecting a menu item that opens a page.

I would like to place an error handler to detect an exception in the page load event.

How can I do this?

 protected void Page_Load(object sender, EventArgs e)
    {
                Code here, works on my machine, but not from user's machine.

                 // Call the error handler if an exception occurs.
                // ErrorHandler("mycode", "Page Load")

    }

Here is my error handler:

private string ErrorHandler(string CodeLine, string strProcName)
    {
        try
        {
             return "Process OK";
        }
        catch (Exception err)
        {
            Session["StackTrace"] = err.StackTrace;
            Session["Message"] = err.Message;
            Session["Data"] = err.Data.ToString();
            Session["Source"] = err.Source;
            Session["ErrProcName"] = strProcName;
            Response.Redirect("~/ErrorHandling/ShowError.aspx");

            return "Process OK";
        }
    }

Thanks,

So if the error is due to the issue in the code in your Page_Load then wrap your page load code inside try catch

Else handle Application level Error event in the global.aspx.

How do I wrap the Pge Load code?

  protected void Page_Load(object sender, EventArgs e)

    {
   
        //Get the connection string

        System.Configuration.Configuration rootWebConfig =
            System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/StockPro");

        if (0 < rootWebConfig.ConnectionStrings.ConnectionStrings.Count)
        {
            connString =
                rootWebConfig.ConnectionStrings.ConnectionStrings["ConStockSelect"];
            if (null != connString)
                Console.WriteLine("StockPro connection string = \"{0}\"",
                    connString.ConnectionString);
            else
                Console.WriteLine("No StockPro connection string");
        }

} // end of page load code

// Where do I put the try, catch statements?
