Q3 upgrade breaks X axis label, show item labels and tooltip code

[Russell Smith]

Hi, 

The following code runs without any issues with the Q2 release but generates errors with the Q3 release:

            RadChart1.ItemsSource = graphList

            For y = 0 To xNames.Count - 1
                    RadChart1.DefaultView.ChartArea.AxisX.TickPoints(y).Label = xNames(y)
            Next y
            For y = 0 To graphList.Count - 1
                    RadChart1.DefaultView.ChartArea.DataSeries(y).Definition.ShowItemLabels = False
                    RadChart1.DefaultView.ChartArea.DataSeries(y).Definition.ShowItemToolTips = True
            Next y

xNames array holds the X axis labels.

After 'RadChart1.ItemsSource = graphList' runs with Q2 'VRadChart1.DefaultView.ChartArea.AxisX.TickPoint' has a collection of TickPoints.  With Q3 there is no collection.  The same is true for 'RadChart1.DefaultView.ChartArea.DataSeries'.  If I omit the code below 'VRadChart1.ItemsSource = graphList' with Q3 the chart shows as expected but obviously without the required axis labels etc.

Any ideas about why the above code does not function with Q3?

Thanks.

Hello Russell,

There are some changes we made to increase performance. Since this.RadChart1.DefaultView.ChartArea.AxisX.TickPoints is an observable collection, you can use the CollectionChanged event and update the values.
