C#

con = new SqlConnection(str);
            con.Open();
            string custom_tb = "select * from customers UNION ALL select * from branches";
            //string branches_tb = "select * from branches";
            //string type_tb="select * from insurance_type";

            dset = new DataSet();
            da = new SqlDataAdapter(custom_tb , con);
            da.Fill(dset, "customers");
            //da = new SqlDataAdapter(branches_tb, con);
            //da.Fill(dset, "combined");
            DataGridView1.DataSource = dset.Tables["combined"];

If this doesn't solve, study SQL Joins. Here's the link to get you started:

Solution 1

For two separate datagridviews, append the following codes to set the datagrids datasource

C#

DataGridView1.DataSource = dset.Tables["customers"];

DataGridView2.DataSource = dset.Tables["branches"];

so you want to join the tables? do they have foreign keys wherein you can connect the two tables? if not, i'll add a new solution.
