.NET Forum / Visual Studio.NET / Extensibility / September 2006DDEX - Data Connections
I have written a Data Provider by extending DDEX and registered it with the VS.NET. However when I close the connection, the red cross mark does not appear on the item (in the server explorer tree control). This works with the SQL Server Provider. What do I need to do to show this red cross mark (icon)? Any help will be appreciated. -K Are you raising StateChanged events on your connection? >I have written a Data Provider by extending DDEX and registered it with the > VS.NET.

Raising the event in the close() method of my ado.net connection object solved this issue.

It's also open source so you can peek under the hood. Be warned though, in order to use Query Builder, you'll need to have a fully-functional GetSchema() method on your Connection object.

I managed to get DDEX support but at the configure tableadapter wizard the "refresh the data table" option is disabled. My command object supports subqueries and I don't know if I'm missing something.

I thought it was something in MySqlDataObjectSupport.xml but again I could not gigure it out. Thanks anyway Robert.

I'm trying to provide this functionality in MySql .Net data provider with no luck. I would really aprecieate any help.

Essentially that feature is hard-coded in VS2005 around the MS providers. It is possible to get the checkbox to un-grey, but that's pretty much all you can contribute to the wizard. The code generation process that implements that option has no hooks to allow you to implement the feature in your provider.
