I have written the following lines of code to retrieve data from database. When I checked through a lable it is showing that the datatable has data, but its unable to display the data in gridview. Can anyone suggest any solution to this.Thanks in advance
    DataSetTableAdapters.retrievebookingTableAdapter rta = new dataSetTableAdapters.retrievebookingTableAdapter();
    DataSet.retrievebookingDataTable rdt;
    rdt = rta.GetData(EmailID.Text);
    GridView1.DataSource = rdt;
    GridView1.DataBind();
    if (rdt == null)
    {
        Label1.Visible = true;
        Label1.Text = "No data found";
    }
    else
    {
        Label1.Visible = true;
        Label1.Text = "data exists";
    }
