views Code for binding gridview works in Single Form app.

One of the child forms in my application is having the grid in which data is bounded in the program.
My code is :


private void SearchForm_Load(object sender, EventArgs e) { dataGridView1.AutoGenerateColumns = false; try { cn = db.createConnection(); if (cn.State == System.Data.ConnectionState.Open) cn.Close(); cn.Open(); cmd = new OleDbCommand("Select BillNo,PartyName,City,State,FORMAT(BillDt,'dd-mm-yyyy')as BillDt from BillMaster", cn); da = new OleDbDataAdapter(cmd); ds = new DataSet(); da.Fill(ds); cn.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message.ToString()); } dataGridView1.AutoGenerateColumns = false; dataGridView1.DataSource = ds.Tables[0]; for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { dataGridView1.Rows[i].Cells[0].Value = ds.Tables[0].Rows[i]["BillNo"].ToString(); dataGridView1.Rows[i].Cells[1].Value = ds.Tables[0].Rows[i]["PartyName"].ToString(); dataGridView1.Rows[i].Cells[2].Value = ds.Tables[0].Rows[i]["City"].ToString(); dataGridView1.Rows[i].Cells[3].Value = ds.Tables[0].Rows[i]["State"].ToString(); dataGridView1.Rows[i].Cells[4].Value = ds.Tables[0].Rows[i]["BillDt"].ToString(); } ds.Dispose(); cmd.Dispose(); da.Dispose(); cn.Close(); }

I debugged the program and checked that each cell is assigned a value from "Immediate window" but records are not displayed in the grid when the from is loaded.

I ran the same code in the Single Form application and it works successfully.
What kind of changes I should make to apply the same code to the MDI Forms application.
Please help.
