GridDataBoundGrid optimisations question

[damien morton]

Hi,

Im trying to optimize my GDBG to speed up the process of adding rows.

I want to add a row to a possibly sorted GDBG and to avoid the cost of re-rendering the full screen.

I notice that when using Grid.SetColHidden(), an optimisation comes into play such that only cells not visible before the operation are rendered, with the rest being handled by a much faster blitting operation.

When using DataTable.Rows.Remove/Insert, I find that the entire grid is re-rendered, or at least a large potion of it. Certainly the performance is nowhere near the hide/show columns operation. Is there a path to inserting and removing datasource rows that enables the blit optimization?

Not much you can do easily. But we'll add an option to the grid not to refresh all when the row count changes.
