How to improve painting performance of DataGridView?

(sorry for bad English)

I have a big problem with performance of DataGridView when it re-paints.

I'm using a DataGridView to show logs from an external application stream. Messages from the stream come in with a high frequency (less than 1 ms). If I add new row to the DataGridView immediately when each new message comes, the DataGridView doesn't have time to re-paint itself before the next message comes.

A possible solution is to use a queue to collect messages and re-paint DataGridView every 100 ms with messages from queue. This is good but the DataGridView blinks when it auto-scrolls to the last row. (Smooth scroll is disabled)

Can you help me to improve DataGridView performance?

When working with large amounts of data, the DataGridView control can consume a large amount of memory in overhead, unless you use it carefully. On clients with limited memory, you can avoid some of this overhead by avoiding features that have a high memory cost.

You can also manage some or all of the data maintenance and retrieval tasks yourself using virtual mode in order to customize the memory usage for your scenario. More detail you can visit dapfor. com
