Subject:Could you provide an example on how to set a week view (8 days) in any resolution of the screen

As my client's requirement, I want to show only 8 days for a week view in any resolution of screen. could you give me some examples to show a view of week (8 days) in any resolution.

i have created different views on scheduler to show a day, week, month, year, ... on a screen they are working perfectly on resolution of 1152x864, but when I change resolution of screen, the duration is changed.

The below code will show me a week(8 days) in scheduler control on resolution of 1152x864 but for higher resolution (i.e. 1600x1200) it show me 10 to12 days on week view.

         ' ( For 1 Week )
        oView.TimeLine.TierArea.UpperTier.Interval = E_INTERVAL.IL_MONTH
        oView.TimeLine.TierArea.UpperTier.Factor = 1
        oView.TimeLine.TierArea.UpperTier.Height = 25
        oView.TimeLine.TierArea.MiddleTier.Interval = E_INTERVAL.IL_DAY
        oView.TimeLine.TierArea.MiddleTier.Factor = 1
        oView.TimeLine.TierArea.MiddleTier.Height = 20
        oView.TimeLine.TierArea.LowerTier.Visible = False
        oView.TimeLine.TickMarkArea.Visible = False
        oView.TimeLine.StyleIndex = "TimeLine"
        oView.ClientArea.DetectConflicts = False
        oView.Tag = "1 Week"


It's an interesting question.

The following code will only show 8 hours, regardless if the windows form hosting the ActiveGantt Scheduler Component is re-sized. This code is not exact, it will sometimes show a few minutes more or a few minutes less:

    Private Sub fResizing_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim i As Integer
        ActiveGanttVBNCtl1.Columns.Add("Column 1", "", 125, "")
        For i = 0 To 100
            ActiveGanttVBNCtl1.Rows.Add("K" & i.ToString(), "Row " & i.ToString, True, True, "")
        ActiveGanttVBNCtl1.CurrentViewObject.TimeLine.Position(New AGVBN.DateTime(2013, 1, 1))
    End Sub

    Private Sub fResizing_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize
    End Sub

    Private Sub mp_OnResize()
        ActiveGanttVBNCtl1.Left = 0
        ActiveGanttVBNCtl1.Top = 0
        ActiveGanttVBNCtl1.Width = Me.ClientSize.Width
        ActiveGanttVBNCtl1.Height = Me.ClientSize.Height
        Dim lTLWidth As Integer = ActiveGanttVBNCtl1.MathLib.GetXCoordinateFromDate(ActiveGanttVBNCtl1.CurrentViewObject.TimeLine.EndDate) - ActiveGanttVBNCtl1.MathLib.GetXCoordinateFromDate(ActiveGanttVBNCtl1.CurrentViewObject.TimeLine.StartDate)
        If lTLWidth > 100 Then
            Dim lSeconds As Integer = 60 * 60 * 8 '8 Hours
            ActiveGanttVBNCtl1.CurrentViewObject.Interval = AGVBN.E_INTERVAL.IL_SECOND
            ActiveGanttVBNCtl1.CurrentViewObject.Factor = lSeconds / lTLWidth
        End If
    End Sub

To use this code just drag an ActiveGanttVBN control onto a Windows Form and override the Load and Resize events.
