Solution 2

To make a large data set work with the DataGridView, you need to put it into virtual mode. 'Large' in this case means over about 10,000, in my experience.

Start your research here[^].

I'm mainly C++, and I knew this worked in ListView, I should have Binged for the DGV version.

In a word DON'T.
You should never need that many rows in your view as it will just mean that your poor user will have to sit twiddling his or her thumbs for hours while your view tries to refresh itself. Use the input information from the user to select the appropriate records from the database (based on the size of the visible portion of your view) and put those in the dataset. When the user needs to see some different data you repeat that operation. you can improve the performance even further by running your database accesses in a background thread.
