you can use <code>GroupName</code> Property of <code>RadioButton</code> Control. if you set the same <code>GroupName</code> for set of <code>RadioButtons</code> you don't need to write the Code Behid which you have written in the above Post/Question, as only one radio button can be selected from the group. but if you want to invoke some action like Disabling <code>TextBox</code> on Particular Radio Button click event you can use following sample code. Example: in this example i'm taking 3 Radio Buttons all set to Same <code>GroupName</code>, hence only one <code>RadioButton</code> canbe selected at a time. when user selects/checks a RadioButton1 i'm Disabling the TextBox1. Note : Please Make sure that your <code>RadioButton</code> <code>AutoPostBack</code> Property set to <code>True</code> otherwise events on <code>RadioButton</code> won't be fired. Design Code: <pre><code><asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:RadioButton ID="RadioButton1" runat="server" Text="DisableTextBox" GroupName="Group1" AutoPostBack="True" OnCheckedChanged="RadioButton1_CheckedChanged"/> <asp:RadioButton ID="RadioButton2" runat="server" GroupName="Group1" AutoPostBack="True"/> <asp:RadioButton ID="RadioButton3" runat="server" GroupName="Group1" AutoPostBack="True" /> </code></pre> Code Behind: <pre><code>protected void RadioButton1_CheckedChanged(object sender, EventArgs e) { if (RadioButton1.Checked) TextBox3.Enabled = false; else TextBox3.Enabled = true; } </code></pre>

1. COAgain... Yeah, that is a solution for this very problem, but for the future I have to know how to force the changes I make in the code behind on any of the controls. So e.g. I want to disable a textbox on a radiobutton selection event. How to do that?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
