Chapter 12 Displaying and Updating Data

bpl · November 24th, 2009, 05:14 PM

When working with Genres.aspx and Reviews.aspx pages I found, that after wrapping content block inside an Ajax UpdatePanel we are not able to make any GridView changes (Edit Columns link from Smart tag) in Design View - they are not refreshed in Source view and gone after we close the page and open again.
(This problem occurred either I working in separate Design View or Split View mode).
So if after wrapping content block inside an Ajax UpdatePanel we need to make any changes in Gridview, we need to commented out Update Panel with ContentTemplate statements, make required changes in GridView, than uncommented Update panel again.
(May be it is bug in ASP.NET 3.5).

Yeah, it mmight be a bug. In that case, consider reporting it at http://connect.microsoft.com

But are you sure it's not a code problem somehow? I just tested it on VS 2008 (with Service Pack 1 applied) and I can edit controls inside an UpdatePanel without any problems.

Cheers,

I also using VS 2008 (with Service Pack 1 applied) and have this problem. Might be, another details of my .NET environment can influence on this? For example, I have in my VS 2008 the latest version Ajax Control Toolkit installed, Silvelight 3 and Microsoft Expression Studio 3.

Everything is possible with software.... ;-)

What happens if you create a brand new web site with just an UpdatePanel and a GridView?

Imar, according to your advice I created brand new website with just an UpdatePanel and a GridView in VS 2008. I got the same provblem after wrapping GridView into UpdatePanel.
On the same PC I also have VS 2005 installed. For testing I created similar project in VS 2005 with just an UpdatePanel and a GridView and did not get any problem when changing GridView wrapped in UpdatePanel.
So some problem exists with VS 2008 environment.
