Question
I am trying to add a new timeitem to an existing layer which already has a timeitem. when i set the new timeitems start and stop time it works, but when i try to change the old existing timeitems start time to the new timeitems stop, it still uses the same old start time, by which the new timeitem is overlaid on the existing timeitem which i dont want. how do i solve this?
Answer
I cannot be sure, but I think you might have forgotten to change the Stop time of the existing time item… Stop must be larger that Start. If this is not it, please send us a (compiling) minimal sample showing this…
Question
Could you give me more details about the Gantt.UpdateMultiSelect function? What is that for?
Answer
You send in a specific time item to the Gantt.UpdateMultiSelect. If the control key is held at the moment, the selection state of the time item will be toggled. If the ctrl is not held, all other time items that might be selected will de-select and the time item in question will be the only one left selected.

Question
I want to horizontal scrollbar at bottom of GANTT chart instead of using Right/Left arrows on the top, how do I make it?
Answer
There is currently no built in support for this. You can add a scrollbar component to the Gantt.TimeItemArea control. Then use the Gantt.DateScaler.TimeSpanSet to set a new view on scrollbar change.
Question
I was able to show task notes icon, as appears in MS Project, by creating custom cell. But I was unable to show desired notes as tooltip, is there anyway to show tooltip on a custom cell image, specific to different rows?
Answer
You can put a string in the GridNode.UserReference and then pick it up in the mouse move event:
private void gantt1_OnGridMouseMove(object sender, System.Windows.Forms.MouseEventArgs e)< ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
{
Cell cell=gantt1.Grid.GridStructure.CellFromXY(e.X,e.Y);
string tooltiptext=””;
if (cell!=null)
{
if (cell.Node.UserReference is string)
{
tooltiptext=cell.Node.UserReference as string;
}
}
toolTip1.SetToolTip(gantt1.Grid,tooltiptext);
}
Question
Is it possible to get a 3 rows in the DataScaler (on for the Month, on for the Week, and on for the day)?
Answer
No. Sorry. The datescaler is fixed to two bands. You can completly override the drawing by implementing the Gantt.OnDateScalerPaintForeground, but it will be some work to get it all in place.

One more question about phGantTimePackage:
How can I show a progress by a task as it is in the Microsoft Project?
Answer
There are two possible solutions depending on your needs.
First; Implement user draw on the time item and draw it yourself, and draw the progress bar as part of the time item.
Second solution; Add another, thinner, time item in another layer. This solution will allow you users to change the progress by click and drag, but you need to move the progress bar time item when the main time item is moved.
