Hello Essoufi,

For creating a multi column headers programmatically you need to add GridColumnGroups to the MasterTableView's ColumnGroups collection. Afterwords, you need to set the ColumnGroupName property of the columns to match the Name property of the created GridColumnGroups:

<asp:PlaceHolder runat="server" ID="PlaceHolder1" />

And the code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    RadGrid RadGrid1 = new RadGrid();
    RadGrid1.ID = "RadGrid1";
    PlaceHolder1.Controls.Add(RadGrid1);
    RadGrid1.Width = Unit.Pixel(300);
    //Add RadGrid to the Controls collection of the placeholder

    if (!IsPostBack)
    {
        RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;
        RadGrid1.MasterTableView.AutoGenerateColumns = false;
        RadGrid1.MasterTableView.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;

        GridColumnGroup columnGroup = new GridColumnGroup();
        RadGrid1.MasterTableView.ColumnGroups.Add(columnGroup);
        columnGroup.HeaderText = "Station XXX";
        columnGroup.Name = "StationGroup";

        GridBoundColumn boundColumn;
        boundColumn = new GridBoundColumn();
        RadGrid1.MasterTableView.Columns.Add(boundColumn);
        boundColumn.DataField = "ID";
        boundColumn.HeaderText = "ID";
        boundColumn.ColumnGroupName = "StationGroup";

        GridDateTimeColumn dateColumn = new GridDateTimeColumn();
        RadGrid1.MasterTableView.Columns.Add(dateColumn);
        dateColumn.DataField = "Date";
        dateColumn.HeaderText = "Date";
        dateColumn.ColumnGroupName = "StationGroup";
    }
}

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(int));
    table.Columns.Add("Date", typeof(DateTime));
    for (int i = 0; i < 5; i++)
    {
        table.Rows.Add(i, DateTime.Now.AddDays(i));
    }

    (sender as RadGrid).DataSource = table;
}

Hope this helps.
