IDataObject Interface

  • Reference

Definition

Namespace:
System.Windows
Assembly:
PresentationCore.dll

Provides a format-independent mechanism for transferring data.

public interface class IDataObject
public interface IDataObject
type IDataObject = interface
Public Interface IDataObject
Derived

Remarks

The IDataObject interface is used by the Clipboard class for data transfer operations like drag-and-drop.

When implemented by a class, the IDataObject methods enable a single data object to offer data in multiple formats. Offering data in multiple formats tends to make the data usable by a wider variety of applications than if only a single data format were supported.

The DataObject class provides a basic implementation of the IDataObject interface.

Retrieves a data object in a specified format; the data format is specified by a string.
GetData(String, Boolean)

Retrieves a data object in a specified format, optionally converting the data to the specified format.

GetDataPresent(String)

Checks to see whether the data is available in, or can be converted to, a specified format; the data format is specified by a string.
GetDataPresent(String, Boolean)

SetData(String, Object)
