Occurs whenever an image is required if you have specified a value for the ImageID property.
ID is the value you have specified in ImageID property. Bitmap is the image to display. It is a TIEBitmap (use OnImageIDRequest if you require a TBitmap). The bitmap is copied in TImageEnMView, and then automatically freed.
Note: ◼You must have specified and ImageID of >=0 or the OnImageIDRequestEx event will not fire (the value of ImageID is not used by ImageEn, so any value is acceptable). ◼The Bitmap you specify for OnImageIDRequestEx will be freed by the control, so ensure you pass a temporary object
