icon in col header & virtual grid

[Administrator]

Hello,

I new to Syncfusion grid. I work with Delphi 8.
I have read in the knowledge base that it was possible to add icons in the column headers by doing this :

Grid[0,1].CellType := ''Static'';
Grid[0,1].CellAppearance := GridCellAppearance.Flat;
Grid[0,1].ImageList := ImageList1;
Grid[0,1].ImageIndex := 0;

this work well when do not work with ''QueryColCount'', ''QueryRowCount'' event.
Are the two things compatible ? Can I work with a virtual grid and add icons in my headers ?
Actually I get the following error message :
''Project Project1 encountered unhandled exception class System.ArgumentOutOfRangeException''.

Thanks,
Verane.

Instead of explicitly setting these style properties in a virtual grid, you will have to provide them dynamically in QueryCellInfo. So, in your QueryCellInfo, you should set these properties on e.Style when e.RowIndex == 0 and e.ColIndex = 1.
