RadComboBox item templated as grid data causes Test Studio to record select item action which fails to correctly click on the item on playback. The select item actions closes the drop down however the page isn't updated as expected. The same scenario works fine on demo site: http://demos.telerik.com/aspnet-ajax/combobox/examples/overview/defaultcs.aspx (see "Product" combobox). Sample test case running against the customer application is attached internally. Work-around: disable the RadComboBox translator so that Test Studio record standard click action over the opened drop down. http://docs.telerik.com/teststudio/user-guide/project-settings/translators.aspx
