On this project. I used XML as a database and AJAX for display.. I integrated this website
Here's the full source code.. please scan it for your safety.
http://www.mediafire.com/?nh14oi1mmeo

First, radiobuttons is assigned before page init..

public partial class Default : System.Web.UI.Page
{
//Assign values as a specific Dynamic WebControl Creation.
List<RadioButton> radioButtons = new List<RadioButton>();
List<CheckBox> checkBoxes = new List<CheckBox>();

Then I created a class that would dynamically create a table containing the available flights depending on session.. (See CallPageLoad())

The placeholder and button is inside the UpdatePanel...

on the button inside the update panel, (btnSelect)

i have this code which works...

protected void btnSelect_Click(object sender, EventArgs e)
{

Label1.Text = Convert.ToString(radioButtons.Count);

It detects the number of radiobuttons that were dynamically created...

But when I use the following code inside the BtnSelectClick event...

foreach (RadioButton button in radioButtons)
{
if (button.Checked == true)
{
Label1.Text = "You select... " + button;

CallPageLoad();
}

}

It does not work even though the dynamically created radiobuttons were already clicked..

Before I integrated to AJAX, this code was working...

Here's the Web Form...

I want line 637 to work (CODE BEHIND) and tried lots of workaround but I just can't get it to work...

Here's the full source code.. please scan it for your safety.

Help please.

I can't help wondering if this is a similar issue to the one I was having with dynamically populated ListBox controls losing their databinds during postbacks.

I will admit, I only skimmed through your code and there is so much going on dynamically that it's hard to say. My thought is that when the radio buttons are dynamically loaded the first time around and then selected... and then the load process is repeated (on call of CallPageLoad()) it may be changing the values of the radioboxes or losing the selected values in the re-processing of the dynamic content.

Perhaps there is some way you can trigger your responses without re-loading the entire process such that the original data is preserved?

Again I could be way off-base here and feel free to completely ignore me lol :P

i'll try to encapsulate the functions inside CallPageLoad()! Thanks for giving me this idea. I'll mark your post useful if ever I get a workaround on this one. Thanks and good day!

Just to clarify, if you can separate your databinds from your selection processes such that the databinds happen once and the selection processes don't repeat the binds unnecessarily I think this might solve your problem.

However, I've spent the last 4 days putting in 12-14 hour days of coding on a C# ASP.Net project of my own and my brain isn't working at peak at the moment ;)

Noted. Thanks man. To tell you honestly, the stress is taking its toll over me. I've got so many pending projects and this is one of them. See ya around.

Another possibility is to add a RadioButtonList, with visible=false into the .aspx in the place where you want the RadioButtons to be.
Then I think dynamically adding the radio buttons (and visible="true") to that existing list will work.

Solved. Thanks everyone. I'mma up everyone's post.

Hmm... this went from solved to unsolved (it was flagged solved earlier) for no apparent reason :P
