Hi Martin,

If the user uses mouse hovering for some time and keys for some time, both should be working fine simultaneously. I have implemented the same by changing PreviewKeyDown event handler in your sample. Please check the below code.

private void ComboEditorProducts_PreviewKeyDown(object sender, KeyEventArgs e)

{

if (e.Key == Key.Space)

{

if (this.itemCheckBox != null)

{

Dispatcher.BeginInvoke(new Action(() =>

{

this.itemCheckBox.IsChecked = (this.itemCheckBox.IsChecked == true || this.itemCheckBox.IsChecked == null) ? false : true;

}),

System.Windows.Threading.DispatcherPriority.Background);

e.Handled = true;

}

else

{

XamComboEditor xamCombo = (XamComboEditor)sender;

foreach (ComboEditorItem item in xamCombo.Items)

{

if (item.IsFocused)

{

if (item.IsSelected)

{

item.IsSelected = false;

e.Handled = true;

break;

}

else

{

item.IsSelected = true;

e.Handled = true;

break;

}

}

}

}

}

else if (e.Key == Key.Up || e.Key == Key.Down)

{

this.itemCheckBox = null;

}

}

The problem that I am facing now is upon unselection of an item using keys, the focus is not retained at same item. Focus is going back to earlier selected item.

Steps:

1) Lets say I have selected item1, item2

2) now I focus item2 which is already selected, press Space key and deselect it.

3) Control/Focus is moving to item1.

I want the focus to be retained at item2.

Thanks,

Bindu

Hello Bindu,

I am not sure I understand the idea that you are trying to implement. If you are able to select/deselect an item on keyboard up/down keys and the latest focused item should be selected/deselected, why do you need to select/deselect item on hovering ? It seems the two approaches are contradictory.

Please let me know if I have misunderstood your requirement.

Hi Martin,

It is working fine as per my requirements.

I want to improvize the same by adding few more requirements.

Is there any way to select/deselect an item either on mouse hover event or keyboard up/down keys ? I am able to do both the things seperately but I dont find a way to club mouse and keyboard events together so that when mouse is hovered on one item and key up/down is pressed to focus another item, it should consider the latest focused item and select/deselect that one by pressing Space key and viceversa.

Thanks,

Bindu
