Gridview delete behavior change from beta2 in VWD express

I've not been able to test this yet in full VS2005 (MS is screwed up with orders for some reason. Has anyone heard this one. All orders for less than quantity=5 were being rejected). So, instead of waiting for it I installed VWD Express. Now, the project had been built in VWD express beta 2, so no big change there.
Several gridview controls in the project had <Delete> enabled. Just <Delete> mind you. Nothing else for command buttons. They all worked fine with delete queries that use gridview.selectedvalue as the parameter. Every single one stopped working since I've converted from beta 2 to RTM!
Here's what I determined. The delete will only work if the row in the grid is selected first!. Otherwise <selectedvalue> is null when you click on <Delete>.
Is this a bug or what?
I'd be happy to supply more details. I am certain others will report this, but I have yet to find a post here or in any blogs out there that reproduce this problem in the RTM of .NET 2.0

On looking more closely at my earlier implementation of <Delete> I realize that the ParameterSource for the key in the grid is actually set to None in dotnet 2.0 beta 2. And it works fine. It seems to just automatically pick up the grid <datakey> value, even when that is a composite key.
My struggles to make <Delete> work again took me down the road of modifying the parameter values which is how I came to my earlier conclusion. Suffice it to say, that <Delete> in the gridview worked very automatically in beta 2. And now, no matter how much I try, the <Delete> function does not work at all.
I will keep playing with it, to see if there is some workaround other than coding things all over again to do deletes in a much more manual way.
Also, I've definitively reproduced my results by moving a working page back and forth from a .NET 2.0 beta 2 and .NET 2.0 RTM environment. Both in a development machine and W2003 server environments. As soon as I take the working page with <Delete> in the gridview from beta 2 to rtm, the <Delete> feature fails.
Anybody else that has a chance to check this out please let me know if you can reproduce this problem.

|||Hate to admit it, but I overlooked an old post here that gave me the hint I needed. Anyway, looking at delete query with SQLprofiler made it very clear. Removing the parameter for the <Delete> and changing the delete query to use the grids datakey field corrected things. Still, I have to compare this asp file to my old beta 2 file and see what happened when I copied it over and used it on the .NET 2 RTM development system. I am sure the behavior changed when I transitioned the project to the rtm version. Hope this saves others some head scatching...
