hi Members, I have a ajax tab container that has several tabs, and I want to use DrawToBitmap to save each visible tab page as a separate bitmap file in an Image folder. My tab pages are created dynamically.

This is my codes:

//Aspx file
            <asp:ScriptManager ID="ScriptManager1" runat="server">
            </asp:ScriptManager>

        <asp:UpdatePanel ID="UpdatePanel1" runat="server">

            <ContentTemplate>

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

//c# file
protected void Page_Load(object sender, EventArgs e)
        {
           BindChart();
        }

public void BindChart()   //generate dynamic chart in different ajax tabs
        {
            //Create new TabContainer
            AjaxControlToolkit.TabContainer container = new AjaxControlToolkit.TabContainer();
            container.ID = "TabContainer";
            container.EnableViewState = false;
            container.Tabs.Clear();
            container.Height = Unit.Pixel(1000);
            container.Width = Unit.Percentage(100);

            if (Listbox1.SelectedValue == "Select All")    //If 'Select All' option is selected from Listbox1
            {
                foreach (ListItem item in Listbox1.Items)
                {
                    if (item.Text == "Select All")
                    {
                        continue;
                    }
                    AjaxControlToolkit.TabPanel panel = new AjaxControlToolkit.TabPanel(); //creating dynamic tabs
                    panel.HeaderText += item.Text;
                    container.Tabs.Add(panel);

                    Label tabContent = new Label();
                    tabContent.ID += item.Text;
                    tabContent.Text += item.Text;

                            //Create dynamic chart in dynamic tabs
                            Chart Chart1 = new Chart();
                            Chart1.DataSource = dt;
                            Chart1.Width = 800;
                            Chart1.Height = 500;

                            Chart1.Series.Add(new Series());
                            Chart1.Series[0].ChartType = SeriesChartType.BoxPlot;

                            List<object> List_CHART = dt.AsEnumerable().ToList<object>();

                            foreach (DataRow row in dt.Rows)
                            {
                                Chart1.Series[0].Points.AddXY(row["TITLE"], new object[] { row["MIN"], row["MAX"], row["25TH_PERCENTILE"], row["75TH_PERCENTILE"], row["50TH_PERCENTILE"], row["AVG"] });
                            }

                            //create chartareas
                            ChartArea ca= new ChartArea();
                            ca.AxisX = new Axis();
                            ca.AxisY = new Axis();
                            Chart1.ChartAreas.Add(ca);

                            //databind
                            Chart1.DataBind();
                            Chart1.Visible = true;

                            panel.Controls.Add(Chart1);
                    }
                }
            PlaceHolder1.Controls.Add(container);
        }

        public AjaxControlToolkit.TabPanel GetManualTab()
        {
            AjaxControlToolkit.TabPanel panel = new AjaxControlToolkit.TabPanel();
            return panel;
        }

Question: Does anyone know how can I use DrawToBitmap() method to save each visible tab page as a separate bitmap file/image in an Image folder?

Thanks for any help!
