RadCartesianChart Drag Points ConvertPointToData Return Null

[Gooi]

I'm using RadCartesianChart to display LineSeries. (How to attach the sample project?)

I'm implementing drag point for certain LineSeries, but always get null value. (See ConvertPointToData_Null.png)

Could anyone help on this?

--> Null data exception

--> Enable drag capability for specific line series only

--> Enable hide/show line series (like add checkboxes to the legend?)

 

Thanks.

Hello Gooi,

For the NullReferenceException, can you post some code showing the exact setup and the drag/drop customization? You can do this here or in your support ticket on the chart topic.
