I have a repeater control, and inside it I have two radio buttons selecting Sex (male, female).
When I save the page, I save the selected value, either "M" or "F", into the data. When I load the page, I want the radio button to be selected based on what's saved.

So, in this case, my repeater has (Container.DataItem).Sex, which equals 'M' or 'F'. How can I use this data in my radiobuttons to select the appropriate value?

This is the kind of function I'd like to use (but it doesn't exist):

```
<asp:RadioButtonList runat="server" SelectedValue='<%# ((Dependent)(Container.DataItem)).Sex %>' />

```

Please note that I am unable to manipulate the radio buttons in the codebehind because I do not have access to the individual repeater items.
