Drop down list always displayed?

[melsawy93]

Hi, Is there a way to have the drop down always shown? It only shows when the box is not blank. Is there also a way to reject any input thats not part of the ItemsSource? Say I enter an invalid value or something.

Thanks. Unfortunately this library does not have such features.

This library doesn't match the use case. This library closes the drop down on some condition, which prevents keeping the drop down shown.

note: this could be related to IsDropDownOpen and StaysOpenOnEdit

My idea is to subscribe Keyboard.LostKeyboardFocus to clear text box when ItemsSource doesn't contain SelectedItem.

note: it depends on when to reject and what to do on rejection

(In other words: You can implement an always-shown drop down combobox without using this library and which I think is better way.)

Closing. Feel free to reopen if someone want to discuss about this issue.
