Title: Not wanting delete from source grid with drag and drop
Post by: WynApse on November 27, 2019, 09:11:51 pm

I've got the drop working as required, but the drag source is being removed.

Is there a setting that I can set somewhere to keep that from happening?

I have a need to drag the same source to multiple drop targets.

Thanks!

It's not feasible to drop single drag source to multiple drop locations.

Just to be clear, I didn't mean a single drag to multiple drops. I meant more of a 'copy' drag where the source record is not removed rather than a 'cut-and-paste' drag where the source record is removed when dropped.

Is that clear?

Yes that makes sense. While it's not feasible to drag ( copy ) from single location and drop ( paste ) on multiple locations in one go, it's possible in multiple gestures.

I assume you need it for DnD between multilple grids.

Default implementation of dropModel.drop deletes rows from origin grid and adds the rows to destination grid.

You can implement your own dropModel.drop callback in which only add operation can be performed without deleting the rows from source grid.

Please take help of this API
