Visual Studio .NET - Throw Exception

System.Web.HttpUnhandledException: Exception of type System.Web.HttpUnhandledException was thrown. 
---> System.ArgumentOutOfRangeException: Length cannot be less than zero.

Parameter name: length

   at System.String.Substring(Int32 startIndex, Int32 length)

   at System.Web.UI.Util.GetScriptLocation(HttpContext context)

   at System.Web.CallHandlerExecutionStep.System.Web.HttpApplication+IExecutionStep.Execute()

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

and the second parameter (length) is less than zero.

Is this what you are asking? This is in the GetScriptLocation method. So I guess your ASP.NET scripts arent' being found. 

Hope that helps.

You have to check the value of the length your are passing.  If it is less than zero, then pass a value of zero.  Most probably you are using another method in the length such as the IndexOf method where if the character is not found it returns -1 as the value.  If this is the case, then you have to change that value to 0.

sub = String1.Substring(0, String1.IndexOf('a') < 0 ? 0 : String1.IndexOf('a'));
