I evaluate your product GTP.NET 2.0. Is it possible to get more information displayed while resizing/moving a TimeItem like a tooltip for the editing DateTime and a vertical line over the TimeItemArea which displays the currently position of the new DateTime? It would be great when the steps of the vertical line would go synchron to the currently displayed DateScalar.
Currently there is nothing built in that you just can switch on, we will probably add something to meet this popular demand. But you can implement tooltips (look in the sample called Gantt_TimeItems) and you could also draw a line using the OnTimeItemAreaPaintBackground Event.
