Datasource-based Diagram not updated if data changes

[Daniel Koffler]

Hello,

my diagram uses DataSource which is defined in DataSourceSettings.

The DataSource property refers to ObservableCollection.

My expectation was that if I change the ObservableCollection at runtime the digram updates accordingly.

However this is not the case.

Also I tried to call the method RefreshDataSource(), but this did not have any effect either.

Kindly let me know how I can dynamically update the diagram if using an ObservableCollection as its datasource.

Thank you

Daniel

We have created and attached a sample for your requirement to change the ObservableCollection at runtime, and the diagram updates accordingly. Please find the sample in the following link.

I hope this sample will satisfy your requirements. If you still have problems achieving your requirements, kindly explain them in more detail; this will help us provide a solution.
