There are a lot of changes we made to the RadGanttView
since Q1 2012. I am afraid that simple substitute might not work as most of the functionality these methods and classes are used for is changed or omitted.
For example, the GridSplitter is no longer used; now the Telerik.Windows.Controls.ResizeControl
is used. Also GanttDragVisualCue is no longer used and a CueTemplateSelector
for various cues is its substitute.
The whole GridView Part
of the RadGanttView is changed to a different control. That said, currently the containers used are more and different than before - EventContainer, SimpleCellContainer, CellConainer, RowSelectionContainer
I suggest getting the new RadGanttView style
If you have any difficulties I encourage you to open a support ticket and attach a sample project demonstrating the issue and we can help upgrade it to the newest version.
