A RadioButtonList can be used to select 1 option within several options. The item "Pizza with egg" is selected by default.

    <asp:RadioButtonList ID="RadioButtonList1" runat="server">
                <asp:ListItem Selected="True">Pizza with egg</asp:ListItem>
<asp:ListItem>Pizza with tuna </asp:ListItem>
<asp:ListItem>Pizza with ham</asp:ListItem>

   </asp:RadioButtonList>

 

Set selected item from Database

If you load Data from a database you sometimes want to select a certain item based on the value in the DB.

You can do so by doing the following:

    string pizzaOptionFromDB = someCode.getPizzaFromDB();  // DB returns  "Pizza with tuna" 
    ListItem li = RadioButtonList1.Items.FindByValue(pizzaOptionFromDB);
    if (li != null)
        {
            li.Selected = true;
        }

This selects the ListItem with the string "Pizza with tuna".

About the Author

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.

The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
