Custom Cell Content

The [FlexGrid] control allows you to include custom cell content when exporting your data into PDF format. The FlexGridPdfConverter allows you to control whether or not custom content gets exported with IFlexGridDrawSettings' customCellContent property, as well as format the cells when you export the FlexGrid by using the formatItem property.
