RadChart axis and ChartSeries don't update when resubmitting form

[Simon]

I'm creating my RadChart progrmatically on postback and making a curve like this,

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)

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.

Hello Simon,

I tried to reproduce a scenario like yours but with no avail. Please find attached a sample demonstrating an update of a series item and its properly update when the value is changed runtime.

Hope this helps.

Kind regards,
