Problem with Drag & Drop within same application

Open MicrotronX opened this issue 6 years ago • 6 comments

If we use i.e. two Grids (file-list) and drag from one to the other grid (each grid has its own tDropComboTarget and tDropFileSource) the destination grid does not accept the file.

if we run the same app twice, we can drag & drop from First-App-Grid-No1 to Second-App-Grid-No2.

This error ocurred after we have upgraded Delphi from Tokyo update 2 to Tokyo Update 3

See #44 and my mail showing this with a demo.

It seems that Drag&Drop has a problem if it is linked to component which is in a form and that form is located within a panel in another form. All Links which are in a normal form are working without problems in both directions copy / paste or drag&drop.

I don't have time for it right now. I have to clean up your demo of all third-party components that I don't own. Or you can send me a demo that works without third-party components.
