[Solved] Where to handle ShowItemLabels?

[Jeff Kershner]

I am handling the RadChart.DataBound event to set the ShotItemlabels to false and the ShowItemToolTips to true, but I am getting a DataSeries = 0 which is causing a crash.

I have a chart declared as a private member in my class:

 

public class TrafficChart : IDomainsTickerChart
{
private RadChart chart = new RadChart();
...

public void Initialize()
{
chart.DataBound += new EventHandler<ChartDataBoundEventArgs>(chart_DataBound);
...

void chart_DataBound(object sender, Telerik.Windows.Controls.Charting.ChartDataBoundEventArgs e)
{
chart.DefaultView.ChartArea.DataSeries[0].Definition.ShowItemLabels = false;

chart.DefaultView.ChartArea.DataSeries[0].Definition.ShowItemToolTips = true;
}

 

 

Here DataSeries[0] = null.  Is this how I should set the ShowItemLabels?
Thanks,
--Jeff

I see what is happening.  This chart is in a transition control, and the second time it is displayed, it calls the chart_DataBound when no data is available.

My bad!   Please close this thread!  :)
