Selected Point on chart

[Mickael]

Hello,

I selected points on my chart by : 

this.monGraph.DefaultView.ChartArea.SelectItem(item);

The data are well selected but I don't see it visually on the chart, it
no color change point or another.

How can I do to it change color?

Best regards,

Hello Mickael,

One possible reason for this behavior is that you need to activate the interactivity settings. For example:

<telerik:BarSeriesDefinition.InteractivitySettings>
    <telerik:InteractivitySettings SelectionMode="Multiple" SelectionScope="Item" />
</telerik:BarSeriesDefinition.InteractivitySettings>

Another reason may be that you are using series that do not render separate items (Line, Spline, Area, Range, and all their stacked versions). For this type of series, the InteractivityScope.Item is not supported. In order to be able to select a PointMark on the line you need to use ChartArea_ItemClick event.

Please review the following help topics:

In case that these directions don't help you to solve the issue, could you please provide more information and code snippets about the implementation of RadChart.
