Question

I have a simple function GetPageName(String PageFileName, String LangCode) defined inside a class file. I call this function from default.aspx.cs file, In this function I am not able to use Response.Redirect("Error.aspx") to show user that error has been generated.

Below is example of Code

public static string GetPageName(String PageFileName, String LangCode)
{
     String sLangCode = Request("Language");
     String pgName = null;
     if ( sLangCode.Length > 6)
     {
        Reponse.Redirect("Error.aspx?msg=Invalid Input");
     }
     else
     {
         try
         {            
             String strSql = "SELECT* FROM Table";

             Dataset ds = Dataprovider.Connect_SQL(strSql);

         }
         catch( Exception ex)
         {
            response.redirect("Error.aspx?msg="+ex.Message);
         }
     }
     return pgName;
}

I have may function defined in Business and Datalayer where i want to trap the error and redirect user to the Error page.

HttpContext.Current.Response.Redirect("error.aspx");

to use it your assembly should reference System.Web.
