Sample project does not save value in custom page

[mhogeweg]

After installing the toolkit in Visual Studio, I create a new toolkit project.

Compiling is fine and running it starts ArcGIS Pro and I can select the custom style as my style.

for a layer I open the editor and see the custom page loaded with the single field.

Entering data and clicking save results the value not being saved in the metadata. In VS the following error is displayed when selecting the page 'Custom Page':

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.ItemsControl', AncestorLevel='1''. BindingExpression:Path=VerticalContentAlignment; DataItem=null; target element is 'ListBoxItem' (Name=''); target property is 'VerticalContentAlignment' (type 'VerticalAlignment')

I had trouble with that control also. I thought a colleague was able to get it to work, but I didn't have a chance to figure out what they did differently to allow that. In the meantime, check out the instructions here in the wiki: https://github.com/Esri/arcgis-pro-metadata-toolkit/wiki/Create-a-custom-page, which direct you to remove the default control and add one that actually works.

It appears that the default control is missing the binding to the XML. The example on the create-a-custom-page page does include that binding.

<TextBox Style="{DynamicResource EditorTextBoxStyle}"
                Text="{Binding XPath=/metadata/custom/myData/trackingStatus, Mode=TwoWay}"/>

also note: the sample on the create-a-custom page page binds the track status to //status

but the XmlDataProvider puts the value in /metadata/custom/myData/trackingStatus

Is there a completed sample of this example code (custom page)? We have a use case for it but seem unable to get it to work locally; have tried on two machines so far.
