DBnulls Cannot Be Converted To Type Integer?
Feb 26, 2010
We are using visual studio 2005 and SSMSE for this project. I had already created some pages which is capable of inserting and updating the values on the sql server. After inserting and updating it will redirect to another page to view the result. When I add a homepage, something just mess up. When I insert a new items for the table, it prompts a message, DBnulls cannot be converted to type integer. When I try to check at the sql tables, the data was inserted but I was not able to view the result on the other page.

I have an asp.net web site where I'm trying to resolve what looks like a problem with ASP.NET AJAX:
Microsoft JScript runtime error:
Sys.ArgumentTypeException: Object of
type
'Sys.Extended.UI.AccordionBehavior'
cannot be converted to type
'Sys.UI.Behavior'. Parameter name:
instance
I've googled around a lot, and looked at the code presented (see below, no idea what it means) but no luck.
I've tried changing scriptmanger scriptmode to release, and a bunch of other things too.
Details:
Visual Studio 2010
ASP.NET 4.0
Ajax control toolkit 4.0
jQuery 1.4.2
jQuery UI 1.8.5
JS Code the error occurs in, inside ScriptResource.axd:
dispose:function()
{
var c=this;
b.UI.Behavior.callBaseMethod(c,eb); --------- this line
var d=c._element;
if(d)
{
var f=c.get_name();
if(f)
d[f]=a;
var e=d._behaviors;
Array.remove(e,c);
if(!e.length)
d._behaviors=a;
delete c._element
}
}
Declaration of accordion control:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="atlas" %>
(snip)
<atlas:Accordion ID="menu" runat="server" SelectedIndex="0"
ContentCssClass="accordionContent" FadeTransitions="true" FramesPerSecond="30"
TransitionDuration="250" AutoSize="None" Width="270">
</atlas:Accordion>
*Update: *
Added accordion control declaration as requested, is there anything else I can add that could be useful?
Does anyone have any idea about this error at all - am I right in thinking it's MS AJAX not playing nicely with other javascript (probably jQuery UI) on the page?

I have a main page with several menu choices, one of which launches an ajax enabled window. The following pattern occurs:If I:
1) Launch site
2) Select menu choice listed on master page that is not ajax enabled
3) Select menu choice that launches ajax enabled popup.
4) close pages
All is OK.If I repeat the steps, but in step 2 I select an ajax enabled page and them launch popup, I get the following error:Message: Sys.ArgumentTypeException: Object of type 'Sys.UI._Timer' cannot be converted to type 'Sys.UI._Timer'.I have spent days on this and have been unable to solve it. If I remove the ajax ToolkitScriptManager and update panels from any of the pages and launch the popup, it works. Can anyone offer some guidance?that are not ajax enabled and then selethat includes an ajax enabled popup window. T

I get the error - Conversion from type 'DBNull' to type 'Integer' is not valid. - on the line.....
Dim newid As Integer = e.Command.Parameters("@latestRowId").Value.........in vb code behind.
I have the identical code for another page with the exception of the field names and it works fine. The only thing I did differently, as far as I know, is I copied the asp and code behind from the page that works into this page and manually changed the field and table names. I don't know what the problem is. Does anyone see any problems?

How can I change the parameter value from Interger to String.
Here below is the part of the code that creates problem; the constant "sqlStatement" is as string, but when the parameters "@ProdColor" read the value it returns an integer instead of the proper type which is a string. I have tried every ting like: CType(sqlStatement(splitItems(1)), string)
Or convert or parse, but it keeps returning the wrong type.
Const sqlStatement As String = "INSERT INTO ProductDetails (ProdID,ProdColor,ProdSize) VALUES"
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray)
cmd.Parameters.AddWithValue("@ProdID", SqlDBType.Int).Value = sqlStatement(splitItems(0))
cmd.Parameters.AddWithValue("@ProdColor", SqlDBType.NVarchar).Value = sqlStatement(splitItems(1))
cmd.Parameters.AddWithValue("@ProdSize", SqlDBType.NVarchar).Value = sqlStatement(splitItems(2))

i am trying to read file from a stream.
and i am using stream.read method to read the bytes. So the code goes like below
FileByteStream.Read(buffer, 0, outputMessage.FileByteStream.Length)
Now the above gives me error because the last parameter "outputMessage.FileByteStream.Length" returns a long type value but the method expects an integer type.

Not sure this is the right forum for this question, but... So in my web apps I have many BLL classes that connect to some TableAdapters/DataTables for data management with the database. I read somewhere long ago that before the project is deployed for live usage, it's a good idea to turn the class files into DLL's, because some performance gain could be achieved. Has anybody ever really tested out this concept?
If my understanding is correct that the whole app gets turned into a DLL anyway the first time it is accessed, is it only the first time the web page is accessed that this might make a difference?

I am running on Windows Server 2003. The former site was a .Net 2.0 website built using VWD 2005 as I recall. I downloaded VWD2010 and upgraded the project (from the fileset on the server). Initially I got an error stating: 'Unrecognized attribute 'targetFramework'.
I went into IIS, clicked properties for my application, and set the ASP.NET version to: 4.0.30319. When I restarted IIS, the project could not find any of the 'pages' (i.e., Page Not Found) for all pages. I ran: aspnet_regiis -i Essentially, the web server acts like the application doesn't even exist with the 'Page Not Found' error. I'm sure this has to be a simple issue - but I can't figure it out so far
