Not all errors catched by global.asax C#

Question

I am attempting to catch all errors except '404-File not found' error in global.asax file and writing in to a text file in server,But lot of errors gets missed ,like FormatException Error,Sessionout Error and "Yellow Page of Error" Appears !

How can I catch all errors here.

void Application_Error(object sender, EventArgs e) 
{
    CT.Bussiness.DevCommonFunctions devTools = new CT.Bussiness.DevCommonFunctions();
    HttpContext ctx = HttpContext.Current;
    //ctx.Response.
    // Get page url
    if (ctx != null)
    {
        string pageName = ctx.Request.Url.ToString();

        Exception ex = Server.GetLastError().GetBaseException();
        HttpException checkException = (HttpException)ex;
        if (checkException.GetHttpCode() != 404)
        {
            string errorDate = DateTime.Now.ToString();
            //string pageName =pageName;
            string errorMessage = ex.Message;
            string errorSource = ex.Source;
            //string errorInnerException=ex.InnerException.ToString();
            string errorData = ex.Data.ToString();
            string errorTarget = ex.TargetSite.ToString();
            string errorStack = ex.StackTrace.ToString();
            devTools.WriteErrorsIntoErrorLog(errorDate, pageName, errorMessage, errorSource, "InnerException", errorData, errorTarget, errorStack);
            //devTools.SendErrorMail("developer3@devwebservices.net,developer4@devwebservices.net,developer5@devwebservices.net,hr@devwebservices.net", errorDate, pageName, errorMessage, errorSource, "InnerException", errorData, errorTarget, errorStack);
            //Response.TrySkipIisCustomErrors = true;
            Response.Redirect("~/Error.aspx");
            //Response.Redirect("Error.aspx");

        }
    }
}

SOLVED

I Followed Like this as KPL Adviced below:

Implemented Elmah
Excluded Global.asax and
Wrote redirection code in web.config.

Thus Solved !

Use:

1.) web.config "customErrors" tag to avoid "Yellow Page of Error":

<customErrors mode="On" defaultRedirect="~/Error.aspx">
      <error statusCode="400" redirect="/error/400-bad-request/" />
      <error statusCode="404" redirect="/error/404-file-not-found/" />
      <error statusCode="500" redirect="/error/500-server-error/" />
</customErrors>

2.) Also try using Elmah to logging errors.

ELMAH (Error Logging Modules and Handlers) is an application-wide error logging facility that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine, without any need for re-compilation or re-deployment.

Once ELMAH has been dropped into a running web application and configured appropriately, you get the following facilities without changing a single line of your code:

Logging of nearly all unhandled exceptions.
A web page to remotely view the entire log of recoded exceptions.
A web page to remotely view the full details of any one logged exception, including colored stack traces.
In many cases, you can review the original yellow screen of death that ASP.NET generated for a given exception, even with customErrors mode turned off.
An e-mail notification of each error at the time it occurs.
An RSS feed of the last 15 errors from the log.

Thanks KPL,I a hearing Elmah for long,Here I : 1. Implemented Elmah 2. Excluded Global.asax and 3. Wrote redirection code in web.config. Thus Solved ! — sajanyamaha, Oct 31 '12 at 06:51
