Databinding of RadioButtonList using SelectedValue...possible?

asp.net

Solution

What you have should work. Are you getting an error? Here's a working example copied from my current project. I'm binding to a nullable bit field - so have a hidden list item to accept the nulls.

<asp:RadioButtonList runat="server" ID="MyRbl" SelectedValue='<%# Bind("MyRblField") %>'
    CssClass="NormalTextBox" RepeatDirection="Horizontal">
    <asp:ListItem Value="false" Text="No" />
    <asp:ListItem Value="true" Text="Yes" />
    <asp:ListItem Value="" Text="" style="display: none" />
</asp:RadioButtonList>

Problem

I am databinding a GridView to an object datasource. The gridview contains a TemplateField which contains a RadioButtonList with ListItems defined inline. I want to be able to databind the SelectedValue of the RadioButtonList to the same underlying table as the other grid columns, but it doesn't work! Do I have my syntax wrong, or is this impossible and requires looping code to individually select the proper item in each row? ``` <llblgenpro:LLBLGenProDataSource ID="llbComputerApplication" DataContainerType="EntityCollection" runat="server"></llblgenpro:LLBLGenProDataSource> <asp:GridView ID="gridComputerApps" DataSourceID="llbComputerApplication" runat="server" AutoGenerateColumns="False" EmptyDataText ="NO APPLICATIONS FOUND FOR THIS COMPUTER." DataKeyNames="ComputerID, ApplicationID" EnableViewState="False" style="border-style:dotted;border-width:thin" > <Columns> <asp:BoundField DataField="ApplicationID" HeaderText="Application ID" SortExpression="ApplicationID" Visible="True" /> <asp:TemplateField HeaderText="Application Name"><ItemTemplate><%#Eval("Application.ApplicationName")%></ItemTemplate></asp:TemplateField> <asp:TemplateField HeaderText="Normalized Name"><ItemTemplate><%#Eval("Application.NormalizedAppName")%></ItemTemplate></asp:TemplateField> <asp:TemplateField HeaderText="Notes"><ItemTemplate><%#Eval("Application.NormalizedNotes")%></ItemTemplate></asp:TemplateField> <asp:TemplateField> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <asp:RadioButtonList SelectedValue='<%#Eval("RequirementOption")%>' ID="rblRequirementOption" RepeatDirection="Horizontal" runat="server"> <asp:ListItem Value="Need Now" Text="Need Now"></asp:ListItem> <asp:ListItem Value="Need Someday" Text="Need Someday"></asp:ListItem> <asp:ListItem Value="Do Not Need" Text="Do Not Need"></asp:ListItem> </asp:RadioButtonList> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="NormalizedNotes" HeaderText="Notes" Visible="False" /> </Columns> </asp:GridView> ```
