How do I get the OK button event in ArcGIS Pro SDK after manually adding a data source to a layer file?

Question

Hi,

In ArcGIS Pro, I have two layer files that only contain symbology. When we manually set the source by right-clicking a layer, the layer properties window opens, and we enter the path to it in the set Data source field.

After that, we pressed the OK button; does anyone know the function/API for that, so that I can retrieve that path from the backend using C# and populate the table names and their corresponding columns in my TreeView controller?

Thanks in advance!

Hi,

You need to listen PropertyChanged event on each layer, o layers you want.

var layerList = MapView.Active.Map.GetLayersAsFlattenedList().OfType<Layer>();
                foreach(var layer in layerList)
                {
                    layer.PropertyChanged += MyLayerPropertyChanged;
                }

private void MyLayerPropertyChanged(object sender, PropertyChangedEventArgs e)
        {
            // your code here
        }
