It is not clear what space you are referring to. If the grid is slightly larger than the form or panel then there may be extra space visible.

I am not using any panel or form. That white space is the background of datagridview.

There does not seem to be a real solution, but here are some workarounds:
c# - DatagridView: Remove unused space? - Stack Overflow[^]

And maybe this:

dataGridView1.RowTemplate.Height = this.dataGridView1.Height / TotalRows;

If you don't want to allow user to scroll down the grid lower than the last row, you have to implement custom painting.

Please, read this: How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control | Microsoft Docs[^]

Note: i'd not recommend to change default behaviour of datagridview painting unless you really need this. I'd change the background color if this "white space" is really annoying you.
