On Mouse wheel event, popup handled and parent control should scroll.

[amit]

Hi,

I am using RadAutocompletebox in scrollable size window. Window has vertical scroll and autocompletebox is at center of window. I have typed a text in completebox and suggestion popup appears and my mouse is on textbox area.Now, I have used mouse wheel event. When i use mouse wheel, popup scroll accordingly to up and down.

My concern is that popup should remain at one place but window can scroll accordingly.

Hi Amit,

The expected behavior when the Popup is opened is that the mouse should be captured and only the opened Popup to be able to be scrolled. When the DropDown gets closed the ScrollViewer  of the Window should be able to be scrolled. That behavior could be observed with the native WPF ComboBox when it is editable - as we try to be consistent with it RadAutoCompleteBox behaves the exact same way.

As we are not exactly sure about the version you are using please, be aware that there was an issue with RadAutoCompleteBox when it is was placed inside a ScrollViewer - the Popup was scrolling when a ScrollViewer inside it was scrolled. The issue has been fixed and is available with the latest official version.

If that is not the observed by you issue please, provide us a sample or a video that demonstrates it and we try provide you with a prompt solution if possible.

Hope the provided information will be helpful for you.
