Hi there.

I am developing a Telerik Silverlight Gantt Chart that uses generic telerik silverlight controls. The problem is that for all general columns (e.g Description, Start, End, etc) the properties are already been created for in a Telerik RadGanttview control except for Predecessor function. Now I want to develop a complete predecessor code and bind it properly to the target column so I can obtain the changes made and submit to the data source. I have tried to implement it but it duplicates the entered value across the rest of other cells in the predecessor column nor does it hold the values after I remove focus. Please, help me solve this problem. A quick response would be very much appreciated.

Thank you.
