Hi Jessie,
Thank you for writing.
For the purpose, you should use the
DragDropService of RadListView. Here is a small example to get you started:
private void DragDropService_PreviewDragDrop2(object sender, RadDropEventArgs e)
{
if (radPanorama1.ShowGroups)
{
TileGroupElement hoveredGroup = radPanorama1.ElementTree.GetElementAtPoint(e.DropLocation) as TileGroupElement;
if (hoveredGroup != null)
{
RadTileElement newTile = new RadTileElement();
newTile.Text = ((SimpleListViewVisualItem)e.DragInstance).Data.Text;
hoveredGroup.Items.Add(newTile);
//newTile.row
//newTile.Column
//newTile.RowSpan
//newTile.ColSpan
}
RadTileElement hoveredTile = radPanorama1.ElementTree.GetElementAtPoint(radPanorama1.PointToScreen(e.DropLocation)) as RadTileElement;
if (hoveredTile != null)
{
TileGroupElement tileGroup = hoveredTile.FindAncestor<TileGroupElement>();
if (tileGroup != null)
{
RadTileElement newTile = new RadTileElement();
newTile.Text = ((SimpleListViewVisualItem)e.DragInstance).Data.Text;
tileGroup.Items.Add(newTile);
}
}
RadPanoramaElement hoveredControl = radPanorama1.ElementTree.GetElementAtPoint(radPanorama1.PointToScreen(e.DropLocation)) as RadPanoramaElement;
if (hoveredControl != null)
{
RadTileElement newTile = new RadTileElement();
newTile.Text = ((SimpleListViewVisualItem)e.DragInstance).Data.Text;
hoveredControl.Items.Add(newTile);
}
}
else
{
RadTileElement newTile = new RadTileElement();
newTile.Text = ((SimpleListViewVisualItem)e.DragInstance).Data.Text;
radPanorama1.Items.Add(newTile);
}
}
I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
