    IProjectWindow Interface
    In This Topic
    Use this interface to select items and retrieve the current selection
    Syntax
    public interface IProjectWindow 
    Public Interface IProjectWindow 
    Example
    Select an item in the Catalog pane
    //Get the catalog pane
    ArcGIS.Desktop.Core.IProjectWindow projectWindow = Project.GetCatalogPane();
    //or get the active catalog view...
    //ArcGIS.Desktop.Core.IProjectWindow projectWindow = Project.GetActiveCatalogWindow();
    
    //eg Find a toolbox in the project
    string gpName = "Interacting with Maps.tbx";
    var toolbox = Project.Current.GetItems<GeoprocessingProjectItem>().FirstOrDefault(tbx => tbx.Name == gpName);
    //Select it under Toolboxes
    projectWindow.SelectItemAsync(toolbox, true, true, null);//null selects it in the first container - optionally await
                                                             //Note: Project.Current.GetProjectItemContainer("GP") would get toolbox container...
    
    //assume toolbox is also under Folders container. Select it under Folders instead of Toolboxes
    var foldersContainer = Project.Current.ProjectItemContainers.First(c => c.Path == "FolderConnection");
    //We must specify the container because Folders comes second (after Toolboxes)
    projectWindow.SelectItemAsync(toolbox, true, true, foldersContainer);//optionally await
    
    //Find a map and select it
    var mapItem = Project.Current.GetItems<MapProjectItem>().FirstOrDefault(m => m.Name == "Map");
    //Map only occurs under "Maps" so the container need not be specified
    projectWindow.SelectItemAsync(mapItem, true, false, null);
