I'm using the 14.5 Document Imaging evaluation in 2.0 C#.
Can somebody give me a hand with this? My requirement is to be able to drag and drop selected items from a RasterImageList to a RasterImageViewer (or a control containing one). The RasterImageList should also be available as a drop target.
I've tried several things but I can't get drag and drop events to raise. Some guidance would be appreciated and some sample code would be fantastic.
Also, since this seems like such basic UI functionality when using RasterImageList or RasterThumbnailBrowser, I think a demonstration should be added to the examples.
Thanks

Allan,
The attached program is a simple demo based on the project shipped with the toolkit under:
LEADTOOLS14.5\Examples\DOTNET\v11\CS\ThumbnailBrowserDemo
It contains the remark (//Dragging) in the file MainForm.cs for lines that were modified to implement Drag and Drop features.
It contains basic functionality and I tried to keep it simple by including the minimum code needed to do dragging from list items to the viewer control. Microsoft documentation contains more details, including a larger code sample under the help topic for "Control.AllowDrop Property".
Dragging here is done using the file name. There are actually different ways of doing it, and you can change what data to send from the source to the target controls.
Note: This is a v1.1 project to make it usable to more .NET customers, but is should be easy to convert it to v2.0

Updated to LEADTOOLS v19 with Visual Studio 2017. Also changed project to automatically select dll's for running in 32-bit and 64-bit.
Extract to "C:\LEADTOOLS 19\Examples\DotNet\CS\" to use the example.
