MapControl.ExportToMht(String) Method

Exports the control’s data to an MHT file (Web archive, single file) at the specified path.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v23.2.dll

NuGet Package: DevExpress.Win.Map

Declaration

C#

public void ExportToMht(
    string filePath
)

VB.NET

Public Sub ExportToMht(
    filePath As String
)

Parameters

Name	Type	Description
filePath	String	A String specifying the full path (including the file name and extension) where the MHT file will be created.

Remarks

This method exports the current map as an *.MHT file to the specified path calling the PrintingSystemBase.ExportToMht method. Note that the .mht (or an appropriate) extension has to be specified in the path. After an MHT document has been created, it can be displayed in a Web browser. For more information, refer to the PrintingSystemBase.ExportToMht topic.

Note

The MapControl’s data can only be exported if the XtraPrinting Library is available.

• MapControl.ExportToImage - exports the map to an image file;
• MapControl.ExportToMht - exports the map to a *.MHT file;
• MapControl.ExportToPdf - exports the map to a *.PDF file;
• MapControl.ExportToXls - exports the map to a *.XLS file;
• MapControl.ExportToXlsx - exports the map to a *.XLSX file;
