Multiselection with Control

Apr 28, 2010 at 3:30 PM



We have a modified Tree (WPF) on this tree multi selection of equal elements is possible (modified WPF Tree)

now I try to multiselect more elements which are not directly neighbours


for example



|_ element1<-- should be selected

|_ element2

|_ element3<-- should be selected


I create a List with all tree items which should be selected


and then:


Keyboard.Instance.HoldKey( KeyboardInput.SpecialKeys.CONTROL );
foreach( TreeNode node in selectedNodes )
AutomationElementHelper.ScrollAutomationElement( node.AutomationElement );


but not all items are selected :(


any ideas


with shift over group of elements it works

public void Select(); - Deselects any selected items and then selects the current element. I would guess that's part of your issue. You may want to try ...... public void AddToSelection();

thanks for answer

I'm not sure that tree elements have  AddToSelection().  I will have a look after vacation.

I have tried also with Click().

can you also try with 0.20 of white as there were some issues with scan code causing the special keys to not working right in earlier versions of white.
