hope this will help u ...

try on page load like this

try
       {

                     string      str = "select ReqId,FileNo,ReqControlNo,Requester,ReqDate,ReqTime,IssueDate,IssueTime,ReceivedDate,ReceiveTime from Issue where ReceivedDate between '" + txtReqDatefrom.Text + "' and '" + txtReqTo.Text + "' AND ReqControlNo='" + Session["ReqControlNo"].ToString() + "' order by ReceivedDate";

           }
           SqlDataAdapter da = new SqlDataAdapter(str, Db.GetConnection());
           DataTable table = new DataTable();
           table.Locale = System.Globalization.CultureInfo.InvariantCulture;
           da.Fill(table);
           GridView1.DataSource = table;
           GridView1.DataBind();
           GridView1.Visible = true;
       }
       catch (Exception ex)
       {
           Label1.Text = ex.ToString();
       }

note:replace Db.GetConnection() to your connection object

You need to use a DataAdapter to fill a DataSet and then use that to create a BindingSource. Then use the BindingSource as the DatagridView's DataSource. Lots of Sources involved, none of which include HP Sauce for the bacon, so here is a simple example:-

string connectionString = "your Connection String";
            SqlConnection conn = new SqlConnection(connectionString);
            SqlDataAdapter da = new SqlDataAdapter("Select * From yourTable", conn);
            SqlCommandBuilder cmd = new SqlCommandBuilder(da);
            DataSet ds = new DataSet();
            da.Fill(ds, "yourTable");
            BindingSource bs = new BindingSource(ds, "yourTable");
            dataGridView1.DataSource = bs;

just put that in the form load event, obviously with your correct sql query and table name.

Hope that helps

ok if you are using datatable and has gridview control
than

datatable dt=new datatable();
gridview1.datasource=dt;
