View 1 RepliesI consider myself fairly new to VB.NET, so maybe you could help me here.I have a bindingSource which is bound to a dataset. I have a filter on the bindingsource. My problem is that when I add a new row, with BindingSource.AddNew, even if it does not match the filter criteria, it still isn't filtered out.Could it be that the bindingsource filter never filters out detached rows? If so, what can I do in this situation?

I have created a form in a project with some controls on it and put code behind those controls so they all work as I want them to. I now decide I want to group those controls within, say, a Groupbox to visually isolate them from the rest of the form.
So I select all the controls, delete them, create the new Groupbox, paste the deleted controls back and all looks OK. However, all the controls have now become "detached" from their associated events. The events still exist in code and the controls still retain all their properties but the controls no longer function.
Is there a way to "refresh" the project so that the controls are re-attached to their events or do I have to go through each control and do it manually?

I am using VB code behind in Visual Studio 2008 to process data but can't figure out SQLConnection problems. I copied and pasted the connectionstring for my database from the explorer properties window but when I paste it inside the parenthesis of SqlConnection() it gives me an error. Also if I name a variable " dim myconnect As New SqlConnection" in does not give me all of the methods or attributes that are associated with it. Is this a Express Edition limitation or do I need to make some specific declarations to get it to work. this is what I have so far
