Question

I was wondering if any one could help me out; I have a table which looks something like the following:

<table id="Table1" border="0">
    <tr>
        <td><b>1.</b> Question 1</td>
    </tr><tr>
        <td style="border-width:5px;border-style:solid;"></td>
    </tr><tr>
        <td align="left" style="width:1000px;"><input id="Radio1" type="radio" name="Group1" value="Radio1" /><label for="Radio1">Answer1</label></td>
    </tr><tr>
        <td align="left" style="width:1000px;"><input id="Radio1" type="radio" name="Group1" value="Radio1" /><label for="Radio1">Answer2</label></td>
    </tr><tr>
        <td align="left" style="width:1000px;"><input id="Radio1" type="radio" name="Group1" value="Radio1" /><label for="Radio1">Answer3</label></td>
    </tr><tr>
        <td align="left" style="width:1000px;"><input id="Radio1" type="radio" name="Group1" value="Radio1" /><label for="Radio1">Answer4</label></td>
    </tr><tr>
        <td style="height:30px;"></td>
    </tr><tr>
        <td><b>2.</b> Question 2</td>
    </tr><tr>
        <td style="border-width:5px;border-style:solid;"></td>
    </tr><tr>
        <td align="left" style="width:1000px;"><input id="Radio2" type="radio" name="Group2" value="Radio2" /><label for="Radio2">yes</label></td>
    </tr><tr>
        <td align="left" style="width:1000px;"><input id="Radio2" type="radio" name="Group2" value="Radio2" /><label for="Radio2">no</label></td>
    </tr><tr>
        <td style="height:30px;"></td>
    </tr>
</table>

How do I go about looping through each group of radio buttons and getting the text of the selected radio button?

The code displayed above is created dynamically … in my aspx file I have the following code:

   <asp:Table ID="Table1" runat="server">
        </asp:Table>

It sounds like you’re starting with a barebones <table> in your markup page, and dynamically adding those <input> afterwards.

Consider taking this approach:

1. Add the runat="server" attribute to your table.
2. In the code where you’re adding those <input> tags, add a new RadioButton control. Use an ID here that you can predict later. Perhaps you can use a RadioButtonList instead, if the choices are logically grouped!
3. It’s unclear if you’re manually adding those <tr> and <td> as strings. Consider the option of new TableRow() and new TableCell(). Then add the new RadioButton to the TableCell.Controls collection with tc.Controls.Add(myNewRadioButton);
4. In your postback code, simply refer to your RadioButton controls by id, or even loop through the Controls collection property of the Table1.

foreach (Control x in Table1.Controls)
{
    if (x.GetType().ToString().Equals("System.Web.UI.WebControls.RadioButton"))
    {
         if (((RadioButton)x).Checked)
         {
             //proceed.
         }
    }
}
