ASP.NET CUSTOM ERROR PAGE
ASP.NET CUSTOM ERROR PAGE
There is simple TWO step to create custom error in asp.net using c#
1- create a error.aspx and coding in error.aspx.cs
2- create a Global.asax page and coding in this page inside Application_Error event.
stept 1- error.aspx
<h4 id="errordetail" style="color: #CC3300" runat="server"></h4>
<asp:Literal ID="lit" runat="server"></asp:Literal><br />
<h4 style="color: #CC3300">Error - Please contact to administrator. </h4>
step 2- error.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
try
{
string strERef = Request.QueryString["ERef"];
//Create Exception object from application variable
Exception oException = (Exception)HttpContext.Current.Application[strERef];
if (HttpContext.Current.IsDebuggingEnabled == true)
{
if (oException.InnerException.Message != null)
{
errordetail.InnerText = oException.InnerException.Message.ToString();
lit.Text = oException.StackTrace.ToString();
}
}
//Remove application variable
HttpContext.Current.Application.Remove(strERef);
}
catch (Exception ex)
{
}
}
protected void Page_PreInit(object sender, EventArgs e)
{
if (Request.QueryString["aspxerrorpath"] != null)
{
if (Request.QueryString["aspxerrorpath"].Contains("Modal"))
{
this.MasterPageFile = "~/MasterPage/TelerikModel.master";
}
}
}
step 3- global.asax
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
// Server.Transfer("~/Error.aspx", true);
string strERef = Guid.NewGuid().ToString();
Exception objError = Server.GetLastError();
Application.Add(strERef, objError);
Server.ClearError();
Response.Redirect(string.Format("~/Error.aspx?aspxerrorpath={0}&ERef={1}", HttpUtility.UrlEncode(Request.RawUrl), strERef), true);
}
