I have created a RadGridView and added custom column to display ChartView in it. I am using SetContentCore method to filter data for each row. 

The above feature works fine, but I face one problem. Whenever we try to resize the parent window manually, the SetContentCore method getting called repeatedly which in turn creates multiple chart element within one column.

Please help to find which event triggers this method call, so that I can disable the same.

Hello, 

The SetContentCore method of the custom cell is expected to be called very often in a similar way like the CellFormatting event is being fired. Its purpose is to ensure that the proper data is displayed in the grid cells. Since RadGridView reuses its visual cell elements due to the data virtualization, the SetContentCore method is expected to be called whenever user interaction is being executed, e.g. mouse hover, scrolling, etc. 

If you populate any data points in the hosted chart in this method, please make sure that you first clear the existing data points before adding the relevant ones for the currently associated row.

In case you are still experiencing any further difficulties, I would kindly ask you to submit a support ticket from your Telerik account and provide more details about the exact scenario you have and how to replicate the undesired behavior locally. A sample project would be quite useful. Thus, we would be able to investigate the precise case and provide further assistance.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

I am creating a custom chart column. Clearing it each time when we do load does the trick. Thanks once again.
