将控件添加到用户控件

Question

I created a user control with WPF which is supposed to take in a list of controls as its content. I succeeded in creating such a user control, but have run into the issue that I cannot name any of the sub-controls I added.

Here's the code for the user control:

public static DependencyProperty InnerContentProperty = DependencyProperty.Register("TaskListItems", 
typeof(UIElement), typeof(TaskList));

public UIElement TaskListItems {
    get { return (UIElement)GetValue(InnerContentProperty); }
    set { SetValue(InnerContentProperty, value); }
}

And the XAML (relevant part):

<ScrollViewer>
    <ContentControl Content="{Binding TaskListItems, RelativeSource={RelativeSource AncestorType={x:Type local:TaskList}}}"/>
</ScrollViewer>

The implementation then looks like so:

<uc:TaskList Grid.Column="0" HeaderText="Daily Task List" FooterText="Completed: 10">
    <uc:TaskList.TaskListItems>
        <StackPanel>
            <Button Content="Some Button"/>
            <Button Content="Some Button 2"/>
         </StackPanel>
    </uc:TaskList.TaskListItems>
</uc:TaskList>

So when I add a control to my user control such as a button for example, everything works fine, except I cannot give the button a name and I get the error:

Cannot set Name attribute value 'test' on element 'Button'. 'Button' is under the scope of element 'TaskList', which already had a name registered when it was defined in another scope

So my question is, is there a way to functionally do the same thing here, but also letting me give my controls names?

Edit for more information:

What I'm going for is a user control that can take in a list of other user controls I created.
Those "list item" controls have four buttons each (the text bit is also a button):

The text button just opens a window with info about the selected task.
The check mark button is supposed to create an event to request the tasks completion.
The vertical ellipsis button opens a window where you can modify the task.
Lastly the x button is supposed to create an event to request cancellation/removal of the selected task.

Issue lies with creating the events and subscribing to them . What I have so far are two event handlers which are invoked in each of the buttons click events.

public event EventHandler<TaskItemEventArgs> TaskCompletedEvent;
public event EventHandler<TaskItemEventArgs> TaskRemoveRequestEvent;

private void acceptBtn_click(object sender, RoutedEventArgs e)
{
    TaskCompletedEvent?.Invoke(this, new TaskItemEventArgs() { EventText = "Task Completed!" });
}

private void removeBtn_click(object sender, RoutedEventArgs e)
{
    TaskRemoveRequestEvent?.Invoke(this, new TaskItemEventArgs() { EventText = "Task Remove Requested!" });
}

The problem now is that I don't know where to subscribe these events to in order to modify the "task item" control that invoked the event. I was thinking I should simply add it in the parent control, but I wouldn't know how to go about that, as all the controls here are dynamic.

Now that I think about it, I guess you wouldn't need a control name for the above task. The dynamic controls have me confused though.

Answer 1

I actually got the code to work now after a bit of experimentation and googling. I dynamically create a stack panel in the TaskList control and when I hit the "plus" button in the top right corner, a dialog opens allowing me to describe my task. After that I dynamically create a TaskListItem and subscribe to it's events with some methods I created in TaskList. Finally I add the TaskListItem to the StackPanel and if I want to modify it I can just modify the specifc object that asked to be edited. Works pretty well.
