C# + ASP.NET web application. Need unique rows and coumns for radio buttons.

I have tried everything from google to tinkering - no luck. I have a 7 by 7 grid of radio buttons. Across the columns are the days of the week. Across the rows (side) are labels. I need for the user to only be able to select one entry per day and one entry ONLY per row.

Using GroupName="Monday" I can easily set a column OR row to only accept one radio button selection but how do I also get both row and column it to only select one?

Help please.

Thanks!

to achieve the functionality you will have to create a work around and there is no direct solution available
the approach what i will suggest set the groupname property but along with that you will have to add a customvalidator control and then manually loop around a set of radio buttons to see if more than one is selected and if yes then thow an error

What if this were being done in a Windows Form?

Below is a quick code behind solution.  Notice all the RadioButtons hav an ID in the format of

"RadioButton" + the row number + the column number

They all go to the same check changed event. I put mine inside an update panel as well.
<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" />
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <table>
                <tr>
                    <th>Label</th>
                    <th>Sunday</th>
                    <th>Monday</th>
                    <th>Tuesday</th>
                    <th>Wednesday</th>
                    <th>Thursday</th>
                    <th>Friday</th>
                    <th>Saturday</th>
                </tr>
                <tr>
                    <td><asp:Label ID="Label1" Text="Label1" runat="server" /></td>
                    <td align="center"><asp:RadioButton ID="RadioButton11" runat="server" oncheckedchanged="RadioButton_CheckedChanged" AutoPostBack="true" /></td>
                    <td align="center"><asp:RadioButton ID="RadioButton12" runat="server" oncheckedchanged="RadioButton_CheckedChanged" AutoPostBack="true" /></td>
