I have a RadGridView which is programmatically created. In a column I have a RadComboBox.
The ItemsSource of the ComboBox is dynamic per line. So it's content will change per line depending on another column's field value. So it is NOT a autocomplete functionality in which the dropdown is created while you type. It is created while you open the list.
At the moment, I am using the DropDownOpened to assign a new ItemsSource to the ComboBox.
The dropdown shows fine, but the values are not written back to the column field once you select an entry and the combo is unfocused. See screenshots: dynamic-??.PNG.
I have tried to use different BindingModes (has to be programmatically) - unfortunately without success.
Thanks for your feedback.
Here is the code:
