Hello my friends,
Did you have a need to populate the DataGridView control with a lot of data? I'm sure you did have.
If you have a huge amount of rows, like 10 000 and more, you will see a huge problem in performance.
To avoid performance leak - you need to set proper value into the RowHeadersWidthSizeMode property.
So the best way is to disable auto resizing during data binding:
dataGridView1.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.DisableResizing;
you actually can set EnableResizing but avoid to use the DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders
The AutoSizeToAllHeaders is most time consumable parameter.
In addition would be better to set the RowHeadersVisible to false
dataGridView1.RowHeadersVisible = false;
Now you can bind data source, and enable it all or set what you want it to be
Thank you, see you next time.
