windows application Add Combobox in Gridview at run time

this method is use to bind table value in dataset;

public DataTable cmbBindGrid()

{

DataAccess da = new DataAccess();

DataSet ds = new DataSet();

try

{

ds = da.GetDataTable("SELECT MPId,MPName FROM MilkatParkarPK");

return ds.Tables[0];

}

catch (Exception ex) { return ds.Tables[0]; }

}

Then

private void namuna8_Load(object sender, EventArgs e)

{

DataGridViewComboBoxColumn x = new DataGridViewComboBoxColumn();

x.DataSource = cmbBindGrid();

x.DisplayMember = "MPName";

x.ValueMember = "MPId";

x.HeaderText = "ekyeRrspk Ádkj";

x.Name = "Test";

x.Visible = true;

x.Width = 170;

dataGridView1.Columns.Add(x);

}
