Forms Data Controls :: Specified Argument Was Out Of The Range Of Valid Values - Gridview?

Nov 23, 2010

I am having problem with this code, even with @Foolongc 's solution. It shows me an error: "Specified argument was out of the range of valid values."

TableCell selectCell = row.Cells[GridView2.SelectedIndex]; --- this is where the problem arises with the SelectedIndex

info about my gridview:

selectedindex = -1 **** when I change it to 0 it gives me the error when I start the page

datasource is programmaticaly stored not design time.

Specified Argument Was Out Of The Range Of Valid Values After Deployment

May 6, 2010

Our logs show hundreds of these errors after our deployment if users are on the site. Anyone know what this means and how to fix it?

Notes:

We are using msdeploy, IIS 6 I recently noticed that our web server's time is about 10 minutes behind the real time, I think that may have something to do with it.

If I log into our site, seems like any file that depends on a WebResource or ScriptResource type file doesn't look right.
