It is just basically is an updated way to go through something similar in the 2.0 framework.
It is more of looping than recursing.

This is nice and all, but there isn't anything recursive about it.

Excellent Job Rizwan! I didn't even go into HTMLControls, but glad it was easy for you to adapt.

Sorry, by the way, I forgot to mention that your code as well as my own code snippet works.

Thanks.

Great article Tom.

In my code, I have a single gridview that contains HTML radio buttons and HTML checkboxes. Although intellisense displays the name of the gridview, the debugger complained.

What I did was this:

GridView targetGrid = (GridView)FindControl("TargetSegmentGridView");

foreach (GridViewRow row in targetGrid.Rows)
{
etc.

Happy coding! :)
Title: Error in text

Comment:
foreach(Control oCtl in ctl.Controls) {
Should read foreach(Control ctl1 in oCtl.Controls) {

Some of this was copied from actual code that I have used and some of the names were changed to protect the innocent, however, I apparently missed something.

My apologies.
