Binding to a Radio Button in Windows Forms

[jehugaleahsa]

Hello:

I have radio buttons bound to boolean properties in a business object.

private void bindRadioButton (RadioButton button, string
propertyName)
{
Binding binding = button.DataBind ings.Add("Check ed",
exclusionBindin gSource,
propertyName,
false,
DataSourceUpdat eMode.OnPropert yChanged,
false);
binding.Control UpdateMode =
ControlUpdateMo de.OnPropertyCh anged;
button.Enabled = exclusionBindin gSource.Count 0;
}

When I click on another radio button, the radio group is cleared
instead of checking the radio button I clicked on. I have to double
click on a radio button to switch it.

I know why this is happening: since my radio buttons are updated
automatically by the data source (i.e., my business object), when I
click off a radio button, no booleans are set. This makes the radio
button group cleared before the clicked-on radio button has a chance
to modify the business object.

Is there a way to get around this?

In time it is happening like this:

1) The ex-checked button realizes it is no longer checked.
2) The ex-checked button updates the data source.
3) The interface realizes a change in the data source and updates the
interface to clear the group.
4) The clicked-on button never gets set because the interface already
cleared the group.
5) I cry a lot and stomp my feet.

Any ideas how to get around this?

Thanks,
Travis
