Update grid with invoke (other thread) slow

[Rene Balvert]

Hi,

We are loading a dataset in another thread and then update the grid.

We use InvokeRequired -> Invoke to update the grid. This is very slow, if we do it directly from our GUI thread the grids updates within a fraction of a second.

(btw InvokeRequired is alway true as we are always calling UpdateGrid (DataSet ds) from our background thread).

What is wrong here?

Regards,

Rene

Invoke is a synchronous call. So, if your thread is constantly, frequently calling Invoke, you can back things up as the calls overrun each other. You could try setting a flag and not initiate another Invoke while there is one in process.
