Hello,
I need to load about 300000 check boxes in several ColumnGrids which takes me nearly 4 seconds. Is there a way to speed this up?
I have already tried to use AddCheckBoxColumn() or AddCheckBox() within a loop and to use BeginUpdate() but there is almost no difference.
Greetings,
Johann
When you need to add that many checkboxes, it's better to use the edDataCheckBox editor type in a TAdvColumnGrid column.
With this setting:
AdvColumnGrid1.RowCount := 3000000;
AdvColumnGrid1.Columns[1].Editor := edDataCheckBox;
it is instant.
How do I do it in C++?
AdvColumnGrid1->RowCount = 3000000;
AdvColumnGrid1->Columns->Items[1]->Editor = edDataCheckBox;
Thank you very much. Just what I needed.
