Hi Peter,
Thank you for using Microsoft Managed Newsgroup Service, I'm Zhi-Xin Ye,
it's my pleasure to work with you on this issue.
Before we go any further, would you mind confirming some points with me?
1. What do you mean of "slow on update(refresh)"? The painting of the
DataGridView is slow or the loading of data in the DataGridView is slow?
2. Do you have large amount of data in the DataGridView?
3. Which version of .NET Framework are you using?
Anyway, you can try the followings:
1. Try DataGridView's SuspendLayout()/ResumeLayout() methods;
2. Try DataTable's BeginLoadData()/EndLoadData() methods to avoid sending
notifications;
3. Try BindingSource.SuspendBinding()/ResumeBinding() method to avoid
sending notifications;
4. Use VirtualMode on DataGridView if you're dealing with large amount of
data;
You can also refer to this feedback and check the workarounds there:
DataGridView rendering is very slow
