   bool createIfNecessary
)

Parameters

createIfNecessary
true (default) to create the pane if it has not already been created

Return Value

An IProjectWindow for the catalog pane or null
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);
