Hi everyone,
I want to simulate the action : drag-drop a item from a listbox to another.

Thanks a lot in advance!

Hi,

We always implement dragging and dropping by handling these events:

MouseDown event: record the index which will be moved.

DragOver event

DragDrop event: remove the item in the old listbox. Insert the item to the new listbox.

ListBox.IndexFromPoint(x,y) method can detect the item index.

Control.DragDrop Event

If there anything unclear, please feel free to tell me.

Best regards,

Ling Wang

Hi Tommy,

Based on my understanding, this issue is more related to Windows Forms, so I'm moving this thread to "Windows Forms General" Forum for better support.

Best Regards,
