Is your feature request related to a problem? Please describe.
I am facing a requirement where it is necessary to drag and drop rows of data grids between data grids and inside the same grid.
Dragging rows (objects) between data grids is not an issue at all, as I am able to define the grid itself as drop area.
Dragging rows inside a datagrid is impossible "from the outside", as I did not find a way to hack it into the rows.

Describe the solution you'd like
This may be solved using the following:

Create an AllowDragDrop property on the RadzenDataGrid
Create an IsDragHandle property on RadzenDataGridColumn
Wrap the grid in a DragAndDropService and provide a proper interface to handle drags and drops in the data source

Describe alternatives you've considered
A complete new grid would be necessary to achieve that feature.

Additional context

This may have impact on the new virtualization feature, which I did not yet test.
This may have impact on a filtered grid

I wanted to discuss the possibility before doing an implemenetation and providing a PR.

@akorchev if you could give me feedback, I could start with a first implementation proposal

@akorchev commented on GitHub (Jun 2, 2021):

I think it would be easier to use the Template of the column and add some component which serves as the drag handle. For now I don't think this should be a built-in feature for the RadzenDataGrid.

Understood.

I think I found a way to implement it without modifying the underlying RadzenDataGridRow. Its a bit like a workaround but will hopefully work.
