I have an ASP.NET form with a DataGrid and Button. I want to put a
RadioButtonList in a DataGrid cell. I bind it to an ArrayList which has a
ListItem in the cell. The display part works fine. I then check some boxes
and hit the submit button. I can't seem to get the value that is selected on
the RadioButton List. I don't want to use the EditTemplate thing I just want
to click on the radiobutton and submit the form. I also don't want to do
autopostbacks when I click on a button. Can this be done?
I looked at this link:
http://support.microsoft.com/default...b;en-us;320707
I modified the code to work with a RadioButton List not just a RadioButton.
However from each RadioButton List when I cycle throug the GridItems it
tells me that one of the buttons in the list was selected but I can't seem
to get which one.
Here is my test:
