Error when ScrollMode is Enabled for the Chart

[DRG]

Works fine when scrolling is not enabled, but throwing the below exception when enabled.
 
 telchart.ClientSettings.ScrollMode = ChartClientScrollMode.XOnly
 telchart.ClientSettings.EnableZoom = True

Have seen this error reported before in the forum, but there is no proper answer on why ? except attaching sample projects that work. Tried adding a series at the end with Line Type but no luck.

 telchart.DataBind()
 telchart.Series.Add(New ChartSeries("Lines", ChartSeriesType.Line))

Hi Dinesh,

I am afraid that (as you have already found out) we do not have sufficient information to reproduce the problem on our side. In order to help you, we will need to observe the problem locally so we can investigate it. It would be best if you could provide a runable project.

We are sorry for the inconvenience.

I have similar problem. My RadChart control is inside RadMultiPage control which is template for detail item in RadGrid control. Data for chart are binded from code behind. Everything works fine until I add tag.

<ClientSettings ScrollMode="Both" EnableZoom="true" />

Hi Marek,

Could you please open a formal support ticket and attach a small project that reproduces the exception, so we can have a look?
