LoadRasterFileData Property

Summary
Gets the file data that has just been loaded.
Syntax
C#
C++/CLI
public RasterDialogFileData LoadRasterFileData { get; } 
public: 
property RasterDialogFileData^ LoadRasterFileData { 
   RasterDialogFileData^ get(); 
} 

Property Value

A RasterDialogFileData class that indicates the file data options associated with the opened file.

Remarks

The RasterDialogFileData.Image and RasterDialogFileData.Thumbnail in this class will be filled when the FilePercent reaches 100. You should use the RasterDialogFileData for reading data only.
