Type Description
BandCollection

A BandCollection object that is the collection of bands contained in a report.

Example

The following example demonstrates how to use the BandCollection class methods to construct a simple report. The AddMarginBands method creates two margin bands and adds them to the collection.

Note

The complete sample project is available in the following DevExpress Examples repository on GitHub: How to programmatically manage report bands.

using DevExpress.XtraPrinting;
using DevExpress.XtraReports.UI;
// ...

public class XtraReport1 : DevExpress.XtraReports.UI.XtraReport {
// ...

    // ...
    // Generated code for the XtraReport1 class.
    // ...

    public void AddMarginBands() {

        // Check if the TopMargin band is already present in the report.
        if(Bands[BandKind.TopMargin] == null) {
            // Create a new TopMargin band and add it to the report.
            TopMarginBand tmBand = new TopMarginBand();
            Bands.Add(tmBand);

            // Create a label and set its text and width.
            XRLabel label = new XRLabel();
            label.Text = "TopMargin Band";
            label.Width = 200;

            // Add the label to the TopMargin band.
            tmBand.Controls.Add(label);
        }

        // Check if the BottomMargin band is already present in the report.
        if(Bands[BandKind.BottomMargin] == null) {
            // Create a new BottomMargin band and add it to the report.
            BottomMarginBand bmBand = new BottomMarginBand();
            Bands.Add(bmBand);

            // Create an XRPageInfo object and set its width and PageInfo option.
            XRPageInfo datePageInfo = new XRPageInfo();
            datePageInfo.Width = 200;
            datePageInfo.PageInfo = PageInfo.DateTime;

            // Add the page information control to the BottomMargin band.
            bmBand.Controls.Add(datePageInfo);
        }
    }

}

The following code handles button clicks to call the AddMarginBands method and show the preview:

XtraReport1 report = new XtraReport1();

private void btnPreview_Click(object sender, System.EventArgs e) {
    ReportPrintTool preview = new ReportPrintTool(report);
    preview.ShowPreview();
}

private void btnAddBands_Click(object sender, System.EventArgs e) {
    report.AddMarginBands();
}
