When the Stored procedure is executed through SQL Server Management Studio, its taking 23 seconds,When the same Stored proc is called through web app, its throwing below copied exception. It is noticed that when the data is more than 100k records this exception is thrown other wise expected records are shown in UI. Another stored proc from the same app returns over 150k records without any excetpion. Can't conclude that the exception is in Stored proc, because it works from SQL Server Management studio, but throws below exception from Web app.
Basically, what I did is that: I have a table in SQL database and some of data fields allow null. I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly. It seems I have issue to retrieve the null value from the database through using objectdatasource through dataset. Any suggestions?An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code

I am trying to write a table output from SQL database to a gridview/ Data List through an Object Data Source. I am a new starter and your help will be useful.
public List<Staff> GetStaff() cmd.CommandType = SqlConnection con = new SqlConnection(connectionstring);SqlCommand cmd = new [code]...
Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.

The program (asp.net/vb) works fine with FormView1_ItemCommand and FormView1_ItemInserted events but strangely objects to FormView1_ItemCreated. Is it only a VC# event?

We have an asp.net 2.0 application in which we get the exception of type 'System.OutOfMemoryException' whenever value is retrieved or stored in viewstate. It does not happen when we test it in local PC but when it is deployed on application server, the exception is thrown.
I have one issue , on that page i have Gridview ie: binding data(by making relationship b/w two tables ) ie: each row contains 75 EasyListbox control so it will be visible as per the condition ie: getting from Database.
But when the page_Loads on that page - First rows shows correctly ie: when i click on paging for Second page - it shows error like this
I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.
The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:
Cannot implicitly convert type 'System.Exception' to 'string'
I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.
I am getting Error Msg Given Below..After Uploading My WebApplication..whenever i try to access my webapplication? what is the exactly reason of this Error. Some time it solved automatically when i try some time later.

I am getting this exception whenever i tried to delete the WCF Service reference in project.I cannot even update it.Our WCF Service is bit huge and looks like this is causing the issue.I Start/Stopped IIS web server but still i cant get rid of it.
All of a sudden I started getting this nasty exception all over the place:
The type initializer for 'System.Drawing.ToolboxBitmapAttribute' threw an exception.
Some relevant observations: * The error started occuring a few hours after the last deployment to the live server, not immediately after. So it basically started occuring of its own accord.
* We have recently moved to a new host (a VPS). The error only occurs on that server, not our local server nor at the old host's (which was a shared environment).
* The problem is basically the same as this: [URL]
* I tried reinstalling Ajax extensions, then our website in IIS, then finally the .Net 2 framework. But the error still occurs after all this.
* The error occurs on line 1, which is just the page directive: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Test.WebForm1" %>
I'm finding it difficult to get a decent trace, but here is one that our CMS provided:

My own code doesn't use the ToolboxBitmapAttribute, but third party products like Peter Blum's and Telerik's do.
Peter Blum replied with some useful hints:
* The "type initializer" concept probably needs some research, but I'm guessing that is an important clue. A quick web search of "type initializer" finds many situations it occurs for a variety of classes.
* The stack trace suggests that this is happening as ASP.NET is compiling your web form. The error is happening as the ASP.NET parser runs. Again this is external from my code (even creating or "type initializing" the attribute is not something my code does).
what is wrong with this syntax datatable temp = (DataTable)du.Rows[0]["NAME"] I get the error message Unable to cast object of type 'System.String' to type 'System.Data.DataTable'.
