I have a GridListControl cell in a grid.
I'm binding the combo to a DataTable that contains a lot of items.
The first appearance of the dropdown list is very slow, so I'm trying to handle it in virtual mode, via the the usual QueryCellInfo/QueryColCount/QueryRowCount events, getting at the embedded grid via grid.CurrentCell.Renderer, but so far I had only so much success.
I can't get the dropdown to appear unless I bind a dummy DataTable to the cell and I can't get the selected item into the cell unless I copy it by myself in the CurrentCellCloseDropDown event.
Please note that I don't want to handle the _grid_ in virtual data mode.
It is the _combo_ that should have the data handled virtually. I'm doing that because binding a datatable containing 200K lines to the combo takes too long.
I attached a project that shows what problems I am having with it:
1) I can't get the selected item from the combo into the grid cell
2) I can't make AutoComplete work for the cell that contains the combo.
Could you please help?
Thanks.
