Hello Michail,
Thank you for writing.
In order to hide the horizontal line illustrating the drop position, you can set the RadGridView.TableElement.
RowDragHint property to
Nothing.
As to the second question, you can customize the target row by using the following approach. Handle the PreviewDragOver event of the RadGridViewDragDropService and change the row's color:
Dim targetRowElement As GridDataRowElement
Private Sub Svc_PreviewDragOver(sender As Object,
e As RadDragOverEventArgs) _
Handles _svc.PreviewDragOver
If TypeOf e.DragInstance Is GridDataRowElement Then
e.CanDrop = TypeOf e.HitTarget Is GridDataRowElement OrElse
TypeOf e.HitTarget Is GridTableElement OrElse
TypeOf e.HitTarget Is GridSummaryRowElement
If targetRowElement IsNot Nothing Then
targetRowElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local)
targetRowElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local)
targetRowElement.ResetValue(LightVisualElement.GradientStyleProperty , ValueResetFlags.Local)
End If
targetRowElement = TryCast(e.HitTarget, GridDataRowElement)
If targetRowElement IsNot Nothing Then
targetRowElement.DrawFill = True
targetRowElement.GradientStyle = GradientStyles.Solid
targetRowElement.BackColor = Color.Red
End If
End If
End Sub
I hope this information helps. Should you have further questions I would be glad to help.
Regards,
