Maptool updates Dockpane UI. How to access to data binding property from other class?

nita14 — Fri, 22 Mar 2024 14:59:19 GMT

Dear Community,

I am struggling to find a way to update an UI element from other class than <*>ViewModel.cs.

I have a docpane with a WaitingCursorControl. Its visibility is cotrolled via data binding in the ViewModel class. However, I do have another MapTool class where I would like to set the visibility of the WaitingCursorControl in the dockpane.

How can access the data binding property from a different class than ViewModel? Any hints?

Thanks!

Adam

Hi,

1. Find your dockpane:

DockPane pane = FrameworkApplication.DockPaneManager.Find(_dockPaneID); if (pane == null) return;

2. Cast pane to you ViewModel class and access public property:

(pane as YourDockpaneViewModel).YourPropertyName = value;

Hi,

Thank you for the snippet. I was somehow close to your solution, did not do casting!

have a nice day,

Adam

@GKmieliauskas Is there a pattern for setting up two-way binding between dockpane elements and an INotifyPropertyChanged enabled class in the dockpane’s view model? I am not seeing anything in the ProGuide and have had no success trying to implement it myself.

Hi,

@Jeff-Reinhart Look at the DatastoresDefinitionsAndDatasets sample. DataPath property has two-way binding. DockPane implements INotifyPropertyChanged. OnPropertyChanged is implemented inside

SetProperty(ref _dataPath, value, () => DataPath);

You can change it to expanded form:

_dataPath = value; OnPropertyChanged();

That example is immensely helpful. Thanks for helping out a C# rookie.
