Set arbitrary value of WPF ComboBox which bound to dictionary

I have the editable ComboBox that using binding to dictionary:

<ComboBox IsEditable="True" ItemsSource="{Binding MyDict}" DisplayMemberPath="Value" SelectedValuePath="Value" SelectedValue="{Binding MyProp}" />

Sometimes I need set in code to property MyProp some different value, that is not presented in the dictionary. In such situation ComboBox is not dispalay the value.

What should I do to ComboBox be able to display arbitrary value in this case?

A ComboBox cannot select arbitrary values. It can only select a value or item that is present in its Items or ItemsSource collection.

So you must add an entry to MyDict before you can select it. You may set the Text property of the ComboBox to a random string, but this won't select any item and set the MyProp property.
