I am using RadGrid, which is using BatchEditing. I am using RadComboBox in a column, which is using LoadOnDemand.
This column is showing PROJECT_ID value in the grid. What I need to do, is to bind Column to show PROJECT_NAME.
Because of optimization, I cannot load PROJECT_NAME as a hidden column to the grid or something like that.
I need some Data source where I will have combinations PROJECT_ID -> PROJECT_NAME and bind it to the column.
This is a solution we are using in different systems.
It is this achievable in Telerik RadGrid and RadCombobox?
