You cannot assign a command object to a datagridview source.

Check this for your correction.

C#

private void button2_Click_1(object sender, EventArgs e)
        {
            if (textBox3.Text == "Hutatma express")
            {
                SqlCommand cm2 = new SqlCommand("Select * from hutatma", con);
                DataTable dth = new DataTable();
                SqlDataAdapter da = new SqlDataAdapter(cm2);
                da.Fill(dth);
                dataGridView1.DataSource = dth;
                cmd = new SqlCommand("select * from traintime", con);
                cmd1 = new SqlCommand("select * from traintime", con);
                trs();
            }
            else if (textBox3.Text == "Sewagram express")
            {
                SqlCommand cm1 = new SqlCommand("select * from sewagram", con);
                DataTable dts = new DataTable();
                SqlDataAdapter da = new SqlDataAdapter(cm2);
                da.Fill(dts);
                dataGridView1.DataSource = dts;
                Image image1 = Image.FromFile(@"D:\asp.net practice\mindicator\mindicator\image\sevagram exp12.jpg");
                label3.Image = image1;
