Hi,

I can't get the pan/scroll functionality to work when reloading the chartview.

Please see the code below. When I call the LoadChart function for the first time in form load event, it works fine. When it is called for the second time in button click event, the pan/scroll does not work (zoom works, however). As You can see, I clear the series and axes in the beginning, I tried both axes.clear and axes.purge, neither of them helps.

Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load
 
     rcvSchedule.ShowPanZoom = True
     LoadChart()
 
  End Sub
 
  Private Sub LoadChart()
   
     rcvSchedule.Series.Clear()
     rcvSchedule.Axes.Purge()
     rcvSchedule.Area.View.Palette = KnownPalette.Metro
 
     Dim horizontalAxis As New CategoricalAxis
     horizontalAxis.LabelFitMode = Telerik.Charting.AxisLabelFitMode.Rotate
 
     Dim bar1DataSource As New List(Of CustomObject)()
     bar1DataSource.Add(New CustomObject() With {.Value1 = 250, .Category = "19.09.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 200, .Category = "30.09.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 25, .Category = "06.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "17.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "18.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "19.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "20.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "21.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "22.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "23.10.2013"})
     bar1DataSource.Add(New CustomObject() With {.Value1 = 300, .Category = "24.10.2013"})
 
     Dim bar1 As New BarSeries()
     bar1.ValueMember = "Value1"
     bar1.CategoryMember = "Category"
     bar1.LegendTitle = "Tot."
     bar1.DataSource = bar1DataSource
     bar1.HorizontalAxis = horizontalAxis
     rcvSchedule.Series.Add(bar1)
 
    
  End Sub
 
  Private Sub RadButton1_Click(sender As System.Object, e As System.EventArgs) Handles RadButton1.Click
     LoadChart()
  End Sub
