Rows in datagridview

Question

I'm using C# i want to make an application which requires me to have a datagridview of 10 columns and 8 rows.

However in design time i can only see one row.

I need all 8 rows visible in designtime as well as run time

So how can i programmatically add rows and make them visible.

I also will need to be able to randomly select values of the datagrid cells and put them into textboxes is this possible?

Thanks
