I am changing my grid data storage to a virtual grid. I was using cell tags to keep information about the cell previously. I am getting a null returned when I attempt to get the cell tag now.
Is there anything I can do to have my data accessed virtally but keep visual information about the cell in a cell tag?
Just as you externally maintain the ''value'' data for a cell in a virtual grid, you would also have to maintain ''tag'' data for a cell. Once you did this, then you could use tags in a virtual grid.
The GridDataBoundGrid is a sort of virtual grid. It uses QueryCellInfo to provide values from its bound data source. Here are a couple of KB''s that discuss maintaining cell properties like Tags for that grid. Doing something for a general virtual grid could be similar.
