I'm creating my RadChart progrmatically on postback and making a curve like this,
This works perfectly first time, the problem occurs when I change values and resubmit the form. The axis and curve don't update, even though my values and the ChartSeriesItem YValues definitely do.
I tried adding the current time to the end of the ChartTitle text and that updates OK every time.
Dim radChart As New Telerik.Web.UI.RadChart()
Dim chartSeries2 As New Telerik.Charting.ChartSeries()
chartSeries2.Type = Telerik.Charting.ChartSeriesType.Line
chartSeries2.Appearance.LabelAppearance.Visible = False
chartSeries2.Appearance.LineSeriesAppearance.Color = System.Drawing.ColorTranslator.FromHtml("#123252")
Dim csItem As New Telerik.Charting.ChartSeriesItem
Dim csItems As New Telerik.Charting.ChartSeriesItemsCollection
For i = 5 To 1000
csItem = New Telerik.Charting.ChartSeriesItem
csItem.XValue = i
'lcyNet(i) is calculated each time based on form input values
csItem.YValue = lcYNet(i)
csItems.Add(csItem)
Next i
chartSeries2.AddItem(csItems)
radChart.Series.Add(chartSeries2)
