Detecting which radiobuttons were changed

[RebLazer]

I have a datagrid that contains a template column that houses one pair of radiobuttons ("Yes" and "No&quot per row. I also have a submit button at the bottom of the page.

The idea is that the initial value ("Yes" or "No&quot is populated from the database. Subsequently the user may be change the radiobuttons' values, then click the submit button to update the database.

How can I detect which radiobuttons were changed in order to only update the database with the values that were changed?


Thanks!

Paul(link9) pointed me at this yesterday and I think this may have exactly what you are looking for.. great article on the datagrid to boot...

http://www.123aspx.com/redir.aspx?res=29947

Part 10 I believe is the section that you will want to focus on for your radio button issues.

Small,

I looked at that article (actually, it's part 11) which pointed me to this

http://metabuilders.com/Tools/RowSelectorColumn.aspx

which does exactly what I want. So I downloaded the code, but after reading through the C# code, I can't seem to find what makes it tick - i.e. how it works. And I am just looking for a small chunk of VB.net code that will do that - not a whole big solution...

Any other places to look?

Thanks,

You can loop through your entire dataset by iterating over the items collection:

for i = 0 to datagrid.items.count - 1
if ctype(datagrid.items(i).findControl("controlName&quot,radiobutton).checked then
'it's checked
else
'it's not checked
end if
next

This is somewhat inneficient, as it will iterate your entire datagrid, rather than how you typically access a single item in the context of a commandEvent handler, but if this is what you need, then that's how you do it.
