Set RadioButtonList check field

[tshad]

I have been trying to use a RadioButton in a Datalist, which works for a Checkbox. But the RadioButton doesn't allow only one button to be selected.

This works but when you change the CheckBox to RadioButton - it displays correctly but does not behave as a set of radiobuttons.

  <asp:DataList ID="lstPermissions" runat="server" RepeatLayout="Flow">
     <ItemTemplate>
	<asp:CheckBox ID="rblPermission" TextAlign="right" runat="server" Text='<%# Eval( "PermissionName") %>'
	  PermissionId='<%# Eval( "PermissionId") %>' Checked='<%# Convert.ToBoolean(Eval( "Assigned")) %>' />
     </ItemTemplate>
  </asp:DataList>

So I changed this to use a RadioButtonList and not the DataList:

<asp:RadioButtonList ID="rblPermission" TextAlign="right" 
	runat="server" Text='<%# Eval( "PermissionName") %>'
	PermissionId='<%# Eval( "PermissionId") %>' 
	Checked='<%# Convert.ToBoolean(Eval( "Assigned")) %>' />

But I get an error that says I can't use Eval with this so I change it to do the Binding in the Code Behind. But how do I do it so it will do the Checked based on the data recieved? As well as my Attribute (PermissionId)?

Thanks,

Tom

If you are binding to a checkboxlist, you will have to loop through your datasource and each rbl item (nested loop) and compare ids, and then check off the items based on that compaison. It will be a manual process, not just a simple .databind().
