The Map control allows you to print and export a map and its vector layer items to multiple formats.

Make sure that your project references the DevExpress.XtraPrinting.20.2 and DevExpress.Printing.v20.2.Core assemblies to be capable of completing the following tasks.

• Immediately Print a Map
• Print a Map Using the Standard Print Dialog
• Print/Export a Map Using the Print Preview
• Export a Map from Code
• Configure Print/Export Options

Immediately Print a Map

To immediately print the Map control’s content without invoking any print dialogs, use the MapControl.Print method.

C#

private void onButtonClick(object sender, EventArgs e) {
        mapControl.Print();
}

VB.NET

Private Sub onButtonClick(sender As Object, e As EventArgs)
        mapControl.Print()
End Sub

Print a Map Using the Standard Print Dialog

You can show the standard print dialog before map printing as the following image demonstrates.

To show the default print dialog before printing, use the MapControl.ShowPrintDialog method.

C#

private void onButtonClick(object sender, EventArgs e) {
        mapControl.ShowPrintDialog();
}

VB.NET

Private Sub onButtonClick(sender As Object, e As EventArgs)
    mapControl.ShowPrintDialog()
End Sub

Print/Export a Map Using the Print Preview

To show the Print Preview dialog with a toolbox or with a Ribbon, use one of the following methods.

Method	Description
MapControl.ShowPrintPreview	Invokes the Print Preview with a toolbox.
MapControl.ShowRibbonPrintPreview	Invokes the Print Preview with a Ribbon.

The code below shows how to invoke the Ribbon Print Preview.

C#

private void onButtonClick(object sender, RoutedEventArgs e) {
      mapControl.ShowRibbonPrintPreview(this);
}

VB.NET

Private Sub onButtonClick(sender As Object, e As RoutedEventArgs)
    mapControl.ShowRibbonPrintPreview(Me)
End Sub

The following code shows how to export a map to the specified PDF file.

C#

private void onButtonClick(object sender, EventArgs e) {
        mapControl.ExportToPdf("D://document.pdf");
}

VB.NET

Private Sub onButtonClick(sender As Object, e As EventArgs)
    mapControl.ExportToPdf("D://document.pdf")
End Sub

In addition, you can export a map vector layer‘s content to one of the supported formats using the following methods.

Method	Description
MapItemsLayerBase.ExportToKml	Exports data from a vector layer using the KML file format.
MapItemsLayerBase.ExportToSvg	Exports data from a vector layer using the SVG file format.
MapItemsLayerBase.ExportToShp	Exports vector layer data to the specified shapefile.

Use the following code to export map vector data to the specified KML file.

C#

private void onButtonClick(object sender, EventArgs e) {
        vectorLayer.ExportToKml("D://file.kml");
}

VB.NET

Private Sub onButtonClick(sender As Object, e As EventArgs)
    vectorLayer.ExportToKml("D://file.kml")
End Sub

Configure Print/Export Option

To configure printing/exporting options, you can use the following code example.

C#

private void onButtonClick(object sender, EventArgs e) {
    mapControl.PrintOptions.PrintMiniMap = true;
    mapControl.PrintOptions.PrintNavigationPanel = true;
    mapControl.PrintOptions.PrintOverlays = true;
    mapControl.PrintOptions.SizeMode = MapPrintSizeMode.Zoom;
    mapControl.Print();            
}

VB.NET

Private Sub onButtonClick(sender As Object, e As EventArgs)
    mapControl.PrintOptions.PrintMiniMap = True
    mapControl.PrintOptions.PrintNavigationPanel = True
    mapControl.PrintOptions.PrintOverlays = True
    mapControl.PrintOptions.SizeMode = MapPrintSizeMode.Zoom
    mapControl.Print()
End Sub

The code above uses the following API members.
