How to delete smart part from Items collection after close it?

Question

I worked in SCSF project and I added multiple views in TabWorkSpace using the following code:

ControlledWorkItem<MyController> controller;
                controller = WorkItem.Items.AddNew<ControlledWorkItem<MyController>>();
                controller.Controller.Run(WorkItem.Workspaces[WorkspaceNames.RightWorkspace]);
                controller.Activate();

and I have a button when I click it will close all opened tabs using the following code:

foreach (var item in WorkItem.RootWorkItem.Workspaces[WorkspaceNames.RightWorkspace].SmartParts)
{
    itemToclose = (UserControl)item;
    if (itemToclose.InvokeRequired)
    {
        itemToclose.Invoke(new MethodInvoker(delegate
        {
            WorkItem.RootWorkItem.Workspaces[WorkspaceNames.RightWorkspace].Close(itemToclose);
        }));
    }
}

After clicking the button, all the smartparts will close but will be still found in the Items collection.
How to remove these smartparts in items collection as well?

Answer 1

The easiest solution based on the code you presented would be to add a WorkItem.RootWorkItem.Items.Remove(itemToClose) inside your delegate.

One thing you should note is that your base Presenter class (if you are using SCSF guidance to create your modules), contains a Dispose method that removes the related view from the Items collection of the Work Item.

They way I have it setup is that when all the Workspaces that belong to a specific Workitem are closed, I call the Workitem.Dispose which ensures that all the SmartParts are removed from the collection.

Hope this helps!
