I have a DataGrid with 3 Columns. I would like to fill the first two columns from one SQL Table and the third column from a separate table. I can easily fill it from one source with a DataSet from my database as shown below, does anyone know how can I use two different sources?

```
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(ds);

dgUsers.DataSource = ds;
dgUsers.DataBind();

```

Thanks in advance for any help!
