When we have ListenForNestedPropertyChange property set to true and at some point Clear of the ItemsSource is called the newly added items to the collection stop to listen for PropertyChanged.
In order to make ListenForNestedPropertyChange work again toggle the value of the property. First set it to false and after that back to true.
As of Telerik v7.0.0 this started to happen. In v6.8.0 the issue doesn't occur. The customer uploaded a sample project in the support ticket.
I have the following issues when there is a DataGrid inside RowDetails template
1. The + does not change to - after expanding the details
2. Clicking the header in the inner data grid of line 2 does not work (seems disabled)
3. Sometimes cannot edit the inner DataGrid. tapping 2 times on the cell does not enter in edit mode
When uprating the row details data, the data does not update in the UI. You have to resize the window, or collapse then expand the row details to see the updated value.
The behavior happens in 7.0.0 version. In 6.8.0 it works as expected.
The DataGrid will crash when there is a bunch of CollectionChanged events with Grouping enabled. This happens in 6.6.0, 6.7.x and 6.8.x versions of the Telerik DataGrid.
