I'm trying to minimize the size of our persisted configuration for a XamGrid. At the moment the configuration is 3400 bytes big. I managed to shrink the size of the configuration by only persisting some properties that are necessary. For example I'm not saving all FilteringSettings but defined the PropertyPath to the properties I needed:

_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "FilteringSettings.FilterMenuSelectionListGeneration",
Options = PropertyNamePersistenceOptions.PropertyPath
});

We want to persist "Width" and the "IsSorted" properties of the columns. At the moment the configuration for these properties looks like this:

_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "Width",
Options = PropertyNamePersistenceOptions.PropertyName
});
_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "IsSorted",
Options = PropertyNamePersistenceOptions.PropertyName
});

Also in this case I want to switch to "PropertyPath" to specify exactly the property I need to persist. The mentioned properties are located in the "Columns" Collection. How can I define the property path such that I achive the behavior? I tried following but it isn't working:

_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "Columns[].IsSorted",
Options = PropertyNamePersistenceOptions.PropertyPath
});
