I have 2 grids with drag and drop capability, one of them is just a simple grid with 2 columns, the other grid is a grid with 3 Hierarchical Templates that have 3 associated BindingSources.
How can I, when dragging and dropping from the simple grid to the hierarchical grid, determine which Template I am dragging the row to and add it to that Template/BindingSources?
I used exactly the example code you have here (https://docs.telerik.com/devtools/winforms/controls/gridview/rows/drag-and-drop), and indeed everything works.
I just wanted to understand if it's possible to know which Template the row is being dragged to and add it exactly to that Template.

Hello,
Thank you for writing.
Here is how you can get the template you are dragging the row into the target hierarchy grid:
private void svc_PreviewDragDrop(object sender, RadDropEventArgs e)
{
var rowElement = e.DragInstance as GridDataRowElement;
if (rowElement == null)
{
return;
}
e.Handled = true;
var dropTarget = e.HitTarget as GridDataRowElement;
var targetGrid = dropTarget.ElementTree.Control as RadGridView;
if (targetGrid == null)
{
return;
}
var dragGrid = rowElement.ElementTree.Control as RadGridView;
if (targetGrid != dragGrid)
{
e.Handled = true;
int hierarchylevel = dropTarget.RowInfo.HierarchyLevel;
GridViewTemplate template = dropTarget.GridControl.CurrentRow.ViewTemplate;
// TO DO
}
}
I hope this helps. Let me know if you have other questions.
