Help Please!

Hi,

I am new to ASP.NET and I am having a hard time figuring out
somethings.

I have an XML file which I read thru and create a form using the
Page_Load. In the form, I have radio buttons which I also create
dynamically. This is done in the actual code not the script.

Now, when i want to save it, I need to access the elements of the radio
buttons. How do I do this? On the on_click event of the button which I
put on the form grid, it complaints that the radio button doesn't
exist.

Any help would be greatly appreciated.

Not sure what the difference is between the code and the script.
Now, when i want to save it
Save what? The value of the radio buttons?
On the on_click event of the button which I
put on the form grid, it complaints that the radio button doesn't
exist.

Are your radio buttons set to runat="server"? If not, you need to add that
in there so the codebehind can 'see' them.

You have to be sure to add the controls on each postback as well. That
way asp.net can map them up to the incoming request/postback. An

This is snippet of how my code is: (in page_load, i call a function
which I created)

.....
while (reader.Read()) {
sb.Append("\t<tr bgColor=\"" + rowColour + "\">\n");
sb.Append("\t\t<td>&nbsp;</td>\n");
sb.Append("\t\t<td>" + detailedQuestion + number.ToString() +
"</td>\n");
sb.Append("\t\t<td>Y <input runat=\"server\" id=\"score_" +
number.ToString() + "_" + subNumber.ToString() + "\" type=\"radio\"
class=\"box2\" name=\"score_" + number.ToString() + "_" +
subNumber.ToString() + "\" value=\"Y\">");
sb.Append(" N <input runat=\"server\" id=\"score_" + number.ToString()
+ "_" + subNumber.ToString() + "\" type=\"radio\" class=\"box2\"
name=\"score_" + number.ToString() + "_" + subNumber.ToString() + "\"
value=\"N\">");
sb.Append(" N/A <input runat=\"server\" id=\"score_" +
number.ToString() + "_" + subNumber.ToString() + "\" type=\"radio\"
class=\"box2\" name=\"score_" + number.ToString() + "_" +
subNumber.ToString() + "\" value=\"NA\" checked></td>\n");
sb.Append("\t\t<td> <div align=\"center\">");
sb.Append(" " + theValue.ToString() + "</div></td>\n");
sb.Append("\t</tr>\n");
.....
....
}
lblformValues.Text = sb.ToString();

On the form designer, I have a button which when clicked on is where I
want to extract the above values which as can be seen are dynamically
created.

Thanks,
