Strange bug (x-posted to aspdotnet, sqlserver)
Date: 01/13/05
Keywords: sql
I'm getting some weird behavior in a function I wrote.
Private Function GetServerStatus() As Integer
Dim strDataSource As String
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim intStatus As Integer
strDataSource = ConfigurationSettings.AppSettings("DSN")
myConnection = New SqlConnection(strDataSource)
myCommand = New SqlCommand("GetSystemStatus", myConnection)
myCommand.CommandType = CommandType.StoredProcedure
myConnection.Open()
intStatus = myCommand.ExecuteNonQuery()
myConnection.Close()
Return intStatus
End Function
It uses the stored procedure "GetSystemStatus":
CREATE PROCEDURE dbo.GetSystemStatus
AS
DECLARE @SystemStatus int
SELECT @SystemStatus=MAX(systemstatus)
FROM Config
RETURN @SystemStatus
GO
The weird behavior is that GetServerStatus() returns -1, but when I run GetSystemStatus in Query Analyzer, it returns 0 (or whatever the value is).

databinding issues... Take two
Date: 01/06/05
Keywords: asp
Hello hello,
Ok so here's (another) ASP.Net 2.0 question...
I've got a GridView that's bound to a table that has several lookups:
Field A, B and C are foreign keys. B & C's values depend on A so if A changes, so must the possible values for B & C.
I store A's value in a Session variable. This works out nicely 'cause in ASP.net 2.0, you can set Select Parameters to values of Session variables. However -- when I change the value of the Session variable, the following error occurs:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I'm guessing that it's due to the following problem: the dropdowns I use for looking up the values of B & C are not happy about re-binding while the row is being edited, either because of the SelectedValue binding or simply because it will not re-bind to the datasource I use for the lookup.
Any idears?

Curious bug, or problem with code?
Date: 01/03/05
Keywords: asp, web, microsoft
I've got a curious error with ASP.NET 2.0 but before I go reporting it to Microsoft, I thought I'd toss it around here:
I've been playing around with the new GridView control and so far it's been quite nice with the new gimmicks -- cuts about 90% of my code straight out. However... Inserting isn't implemented yet. It is, however, implemented in the DetailsView control.
So I decided to tackle the problem this way:
MyForm
|
-------> MyMultiView
|
-------------> View1 => MyGridView, MyInsertButton
|
-------------> View2 => MyDetailsView
I have a form with a multiview. The multiview has two views, one with a Gridview and a button entitled 'Insert', the other with a DetailsView. For viewing/editing/deleting, I use the GridView. For insertion, I switch views to the DetailsView and change mode to insert. So far so good.
Next, when the DetailsView changes modes (back to readonly), I have it switch back to the original view. Here's where the error occurs: any other action throws the following exception...
Description:
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.
Exception Details:
System.Web.HttpException: Failed to load viewstate. The control tree into
which viewstate is being loaded must match the control tree that was used to
save viewstate during the previous request. For example, when adding controls
dynamically, the controls added during a post-back must match the type and
position of the controls added during the initial request.

So -- where is the problem coming from? Am I getting the events screwed up? Is there something I'm forgetting? Or is there really something amiss..?
Just in case, here's the code:
Sub AddActivity_Click(ByVal sender As Object, ByVal e As System.EventArgs)
AdminMultiView.ActiveViewIndex = 4
DetailsView1.ChangeMode(DetailsViewMode.Insert)
End Sub
Sub DetailsView1_ModeChanged(ByVal sender As Object, ByVal e As System.EventArgs)
If Not DetailsView1.CurrentMode = DetailsViewMode.Insert Then
AdminMultiView.ActiveViewIndex = 0
End If
End Sub
