I have followed the project at
http://www.telerik.com/help/silverlight/raddatafilter-how-to-create-custom-filter-editors.html to create a solution that uses a RadComboBox as a custom filter for some fields in a RadDataFilter.
I have been unable however to get the value selected in the RadComboBox to update the underlying FilterDescription, with the Filter always ending up with 'Status isEqualTo <unset>' after selecting an item in the combo box.
I am sure I have followed the project correctly, and have the SelectedValue of the ComboBox bound to the Value property as below.
The only difference I can see to the example code is that I am using the RadDataFilter unbound. It is not bound to a DataGrid, I am setting my own ItemPropertyDefinitions and using the resulting FilterDescriptions in other parts of the project. Is there a way to check that the DataTemplate Value is getting set when the RadComboBox value changes, or do I need to force the FilterDescription to update somehow as it is unbound? Finally, if nothing else is there a way to manually set the Value or update the FilterDescription when the ComboBox value changes?
Thanks
