The Control can be used just like a regular TreeView. If a CheckBoxTreeViewItem hasn't been generated yet (not expanded to) then the source for it won't be in the CheckedItems collection until it has been generated.CheckedItems supports two-way Binding to source.CheckedItems is an ObservableCollection where T is the interal type of ItemsSource.The CheckBoxTreeViewLibrary source can be downloaded here I did debug it and I can see that it does not behave the same way under the dock pane than under windows.Finally got around to update the CheckBoxTreeView with the missing features. In the end, I’m able to compile the code, but once I run it, the dockpane is displayed, but I don’t see the treeview in itself. I had to adapt the code so that I was using Propert圜hangedBase instead of INotifyPropert圜hanged and also adjust the WPF because in a dockpane we are using a usercontrol instead of a window. SetClearButtonVisible(true) Data Binding in WPF TreeGrid (SfTreeGrid) SfTreeGrid. ![]() ![]() I then tried to do the same thing using ArcGIS Pro SDK by creating a dockpane that does the same thing. checkboxes and menu options using Java Servlet, JSON and MySQL - Part 2. The end result is an application that looks like this:Īnd for example, if the user unchecks the Blades checkbox, all the childs (Dagger, Machete and Sword) are then unchecked. The code for that project can be found here: Right now, I’m simply trying to replicate the code from a windows application where we see a treeview with checkboxes. I’ve been developing with ArcObjects and VB.NET for the past 14 years. I’m currently initiating myself to the development of ArcGIS Pro version 2.7, the WPF and the MVVM approach. ![]()
