Reset properties when a dockpane closes [edited: or close an Add-In]

GyanendraGurung

I am trying to figure out:

a. How to reset the properties in the dockpane when it closes [edited: or close an Add-In]. The following code below with "SaveDirectory" is initialized when I open the dockpane for the first time, then even after closing it and opening several different projects, the value of "SaveDirectory" does not change. How do I do that?

b. I thought of resetting the value inside "UninitializeAsync()" method, but I guess "UninitializeAsync()" method is not used for that. 

Thanks.

namespace Test
{
    internal class TestDockPaneViewModel : DockPane
    {
        private string _saveDirectory;
        /// <summary>
        /// Default Directory to save all user input data.
        /// </summary>		
        public string SaveDirectory
        {
            get { return _saveDirectory; }
            set { _saveDirectory = value; NotifyPropertyChanged(() => SaveDirectory); }
        }        
        /// <summary>
        /// Constructor
        /// </summary>
        protected TestDockPaneViewModel() 
        {
            SaveDirectory = System.IO.Directory.GetCurrentDirectory();
        }
        /// <summary>
        /// Called when the pane is uninitialized.
        /// </summary>
        protected async override Task UninitializeAsync()
        {
		    // Reset Default Save Directory when dockpane closes // 
            SaveDirectory = null;
            await base.UninitializeAsync();
        }	
		 
}

Hi,

What do you mean by "Dockpane closing"? By pressing x at the right upper corner you just hide dockpane.

So if it's right place for your reset code, so you can override OnShow Dockpane class method:

protected override void OnShow(bool isVisible)
{
if (!isVisible)
{
SaveDirectory = null;
}
}

UninitializeAsync will be called on ArcGIS Pro closing.
