The MouseMove event is generated continually as the mouse pointer moves across objects. Unless another object has captured the mouse, an object recognizes a MouseMove event whenever the mouse position is within its borders. Use the ItemFromPoint property to get the item from cursor. Use the ColumnFromPoint property to get the column from point. Use the DateFromPoint property to specify the date from the cursor. Use the DrawDateTicker property to draw a ticker as cursor hovers the chart's area. Use the LevelFromPoint property to retrieve the index of the level from the cursor.

The following VB sample prints the cell's caption from the cursor ( if the control contains no inner cells. Use the SplitCell property to insert inner cells ) :

Private Sub Gantt1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    On Error Resume Next
    ' Converts the container coordinates to client coordinates
    X = X / Screen.TwipsPerPixelX
    Y = Y / Screen.TwipsPerPixelY
    Dim h As HITEM
    Dim c As Long
    Dim hit As EXGANTTLibCtl.HitTestInfoEnum
    ' Gets the item from (X,Y)
    h = Gantt1.ItemFromPoint(X, Y, c, hit)
    If Not (h = 0) Then
        Debug.Print Gantt1.Items.CellCaption(h, c) & " HT = " & hit
    End If
End Sub
