I am currently having an issue with radio buttons and grouping. I have an asp radio button within a repeater control. I have the group name attribute set to \"Customer\". Wh

Answer 1

I had to modify slightly the answer posted above by r3dsky.

Here's what worked for me:

$(document).ready(function () {
        $(".divWithGridViewOrRepeater input:radio").attr("name", "yourGroupName");
    }); 

Answer 2

Unfortunately, this is a well known issue with radio buttons within a repeater. One of your only options would be to create a custom server control derived from the RadioButton class and override how it renders.

EDIT: Here's a sample of what the derived class may look like:

public class MyRadioButton : RadioButton
{
    protected override void Render(HtmlTextWriter writer)
    {
        writer.Write("<input id=\"" + base.ClientID + "\" ");
        writer.Write("type=\"radio\" ");
        writer.Write("name=\"" + base.ID + "\" ");
        writer.Write("value=\"" + base.ID + "\" />");
        writer.Write("<label for=\"" + base.ClientID + "\">");
        writer.Write(base.Text);
        writer.Write("</label>");
    }
}

Answer 3

I finally got around this by creating a plain radio button and setting the value using an server-side eval.

<input type="radio" name="radCustomer" value='<%#Eval("CustomerNumber") %>' />

Now when the application performs a postback, I check for the value of Request.Form["radCustomer"]. This works flawlessly.

I had the same issues. I am using Literal as placeholder to render radio button onItemCreated event.

ASP.Net

<asp:Repeater ID="rpt" runat="server" OnItemCreated="rpt_OnItemCreated">
    <ItemTemplate>
        <asp:Literal ID="lit" runat="server"></asp:Literal>
    </ItemTemplate>
</asp:Repeater>

C#

protected void rpt_OnItemCreated(object sender, RepeaterItemEventArgs e) {
    Literal lit = (Literal)e.Item.FindControl("lit");
    lit.Text = "<input type=\"radio\" name=\"myGroup\">";
}
