When you are binding ItemSource to collection, the Height of RadToolbarTray becomes equals null so it's not visible. Can you fix it please?
Declined due to inactivity.
Hello, We are not aware of any issues with the Height of the ToolBarTray in the described scenario. However, this scenario is currently unsupported and the component does not generate RadToolBars when its ItemsSource collection is data bound to a business collection. This item is already logged in the portal - http://feedback.telerik.com/Project/143/Feedback/Details/113281-toolbar-add-a-possibility-to-bind-the-radtoolbartray-and-generate-radtoolbars. If, however, you feel that there is indeed an issue with the Height of the component, please provide us with more details on the steps we can follow to reproduce this behavior.
