How to set that data whole area in gridview?

Hello, I am using the dataGridview开发者_高级运维 control to display some data, but my problem is I have one or two columns of data, the columns will appear in a small part in gridview instead of filling all available space. I want the data to take up all available area in the datagrid. How can I do This? thank you!

You have to set the Column Fill mode.
