Hi Jebarson,

The Chart control supports data binding to custom data sources that implement the IBindingList and optionally the ITypedList interfaces. You can take a look at the following example in our Windows Forms demo application:

All Examples > Data Manipulation > Data Binding > Binding to IBindingList

The example binds the chart to a list of MyCustomObject instances.

I hope this helps.

Hi Jebarson,

The IBindingList interface has the ListChanged event that can notify the chart whenever the data is changed, which is essential for data binding.

If you don't want to bind the data, but just fill it once into the chart you can implement a procedure that copies the fields of each custom object into the respective data series of the chart.

I hope the question is not clearly understood. My question is why do you need IBindingList to bind the data? To bind a data to any object, implementing of ICollection is suffice. If I need the data to be bound automatically whenever the data gets changed, then I can implement IBindingList but if not why should I implement IBindingList.

I think that making IBindingList mandatory is not an good way of implementation. Hope you agree with this.

If you don't need automatic update of the chart when data is changed you can use the data import functionality. Data import can work with IEnumerable - you can take a look at the FillFromEnumerable method of the NDataSeries type.
