You need to use UNION. But keep in mind you have to select the same number of columns from both tables.

SELECT This,That,Other FROM Table1
SELECT This2,That2,Other2 FROM Table2

Here's the process for displaying data from a database in a gridview:

Get data from database (look up SqlCommand, SqlConnection, sql queries using union or join)
Convert data into usable format (look up SqlDataReader and SqlDataAdapter)
assign usable data to datagridview datasource.( this is literaly datagridview1.DataSource = myarrayofdataobjects; )

Now you know what to study to do this. But if you're a computer science or IT student and this is for a project, All of this should be in your handbook or course material. If it isn't, You should ask you lecturer about it.
