I have a radcombobox with AllowMultipleSelection set to true.
When loading a window I want to set the selected items in that combo box from values obtained from a database. But I can't seem to see how the values can be set if I set the ItemsSource to a string[]
As an example
string[] items = new string[] {"1", "2" "3", "4"};
OptionCombo.ItemsSource = items;
Then I want to set "2" and "4" to selected.
Thanks
