MayCopyInternal Method

This predicate is true if the user may copy the selection on an internal drag-and-drop.

Syntax

protected virtual bool MayCopyInternal( 
   DragEventArgs e
)

Parameters

e

Return Value

False if the AllowedEffects does not allow copy. False if Shift key modifier applies (trying to require a move). False if the diagram Northwoods.GoXam.Diagram.IsReadOnly or does not Northwoods.GoXam.Diagram.AllowInsert. False if the drag-and-drop came from another control. False if the model is not Modifiable. Otherwise true.

Remarks

Despite the list of conditions that cause this method to return false, if this Northwoods.GoXam.Diagram is a Northwoods.GoXam.Palette, this will return true as long as the AllowedEffects allows Copy and as long as the Shift key is not held down. If you also set AllowDrop to true on the Palette, it avoids showing a "drop-not-allowed" cursor within the Palette, even though a drop really isn't allowed into the Palette.
