Fires when an OLE drop action occurs on the PageLayoutControl.
[Visual Basic .NET] Public Event OnOleDrop As OnOleDropEventHandler
[C#] public event OnOleDropEventHandler OnOleDrop
[C++]
HRESULT OnOleDrop(
esriControlsDropAction dropAction,
VARIANT dataObjectHelper,
long* effect,
long button,
long shift,
long X,
long Y
);
[C++]
Parameters dropAction [in]
dropAction is a parameter of type esriControlsDropAction dataObjectHelper [in] dataObjectHelper is a parameter of type VARIANT effect [in, out] effect is a parameter of type long button [in] button is a parameter of type long shift [in] shift is a parameter of type long X [in] X is a parameter of type long Y [in] Y is a parameter of type long
If the IPageLayoutControl::OleDropEnabled property is set to False the OnOleDrop event will not be triggered, and the esriDragDropNone effect will display when data is dragged over the control.
If the IPageLayoutControl::OleDropEnabled property is set to True the esriControlsDragDropEffect must be set each time the OnOleDrop event is triggered.
Use the esriControlsDropAction constant to determine whether the data is entering or leaving the control, or whether data is being dragged over or dropped onto the PageLayoutControl.
Use the esriDropOver dropAction to display mouse coordinates while data is being dragged over the PageLayoutControl from another application, as the OnMouseMove event will not be triggered.
