Data Binding RadioButton to enum via code

Posted By:      Posted Date: September 27, 2010    Points: 0   Category :WPF

I was reading this solution on how to bind a RadioButton to a enum type, but in my special case I need to do it programmatically since I am generating a number of panels with 3 radiobuttons the number of which is only known runtime.

I tried this: 

Binding b = new Binding("CerradaBind");
        b.Mode = BindingMode.TwoWay;
        b.Source = _exp3Class;
        _gpuertas[i].BotonCerrada.SetBinding(_gpuertas[i].BotonCerrada.IsChecked, b);

But found out the IsChecked property is not what the Setbinding function expects, how should I do it?

Also, is there another way of binding directly to radiogroup instead of button by button?

Binding RadioButton to an Enum property



Hi guys,

I have noticed a weird behavior on databinding some radiobuttons to an enum property.

- an enum dependency property on a Window (eg: property Test of type Visibility);
- three radiobuttons to display and select the value of the property, one for every enum value (eg: Visible, Hidden and Collapsed)
- a converter that converts and converts back the value of the property to the radiobutton's IsChecked property

The weird behavior is that when I click on a radiobutton the value of the property changes, but if I assign via code a new value directly to the property, the radiobuttons get disconnected from the property, resulting in not changing anymore the value of Test property when a radiobutton is clicked.

I created a test project in which you can select, using the radio buttons, the value of the Test property, and if you click the 'Test' button, the value is assigned to the Test property by code.
In the second part of the window there is the same thing with the SelectedIndex property of a ListBox, bound to a TestIndex property, this time without a converter.

If you launch the project, and first of all click on the Test button, the value of the property changes, but now, if you change the selection on the radiobuttons, the property never changes again if you click 'Visible' or 'Hidden'
