A bug has been introduced in the RadListView control in one of the newer releases: When the control is set to DetailsView the ItemMouseDoubleClick-even will always fire twice. This is not the case when the RadListView has the ListView or IconsView ViewType. To repoduce the bug: Create a new project with a new form, add a RadListView and a few items to the ListView, set ViewMode to DetailsView, add the event and marvel at the event firing twice.
Thank you for this sample project, it allowed me to reproduce the issue. I am changing its status to Approved and we will look into it when we work on improving RadListView.
I might have described it a bit poorly, you have to double click on the item itself (I.e., the text/something that's in a column) to trigger the bug, if you just double click on the row (outside of the column area) it won't be triggered. The version I'm using is 2014.3.1104.40, I made a quick "demo" of the bug in a simple project, attaching the form files below.
Hi Lars, I have tested the described case, however the event is triggered only once on my end, hence I am declining this item. Should you still experiencing this issue, please contact our support team for further assistance.
