    <p>Well, I have been scratching my head for some time now. But failed to find solution to my problem. What I have is a MainViewModel with and ObservableCollection TabItems. The MainViewModel is set as DataContext for the MainView (User Control) which in turn hosts the TabControl. The tabcontrol is bound to TabItems collection. The Content of the tabcontrol will be ReportItems User Control.</p> <p>This setup is basically for report for reporting UI for SSRS. The first tab contains a list of Reports selecting which would show a few listboxes from where the user would select the Report Parameters. Not after selecting parameters, the user click a button which in turn generates a report and adds a tab to the tab control with the reporthost.</p> <p>The reason I am trying to select the report from a tab and not the Main View is that there are a lot of parameters to be selected and if I add the listboxes to the MainView, the space left for the tabcontrol would be less and the user would need to scroll down to view the reports. </p> <p>I am not sure if my design is flawed but I wanted to figure out a way to add the new ReportItemViewModel to be added to the TabItem collection. That means allowing a child tab to add a sibling by sending a ReportItemViewModel object to MainViewModel and add to the colection.</p> <p>I thought of using a static Collection to do so but that would not call my OnPropertyChange method. Also, having a static method in the MainViewModel does not help as it would not be able to add the object to the collection since the collection is not static.</p> <p>I am not posting any code here since I am stuck at how to begin itself. I looked at another post <a href="https://stackoverflow.com/questions/3064365/adding-tabs-to-tabcontrol-from-inside-usercontrol">here</a> but could not figure out how to use it.</p> <p>Sorry for long description, Just wanted to make the question clear.</p> <p>I am open to any suggestion, also if I can get a better design. I am desperate and any help would be appreciated.</p>

    1. COYou could use a popup or an expander to host the UI for the adding process. that way you don't use screen real estate and you don't write adding logic in yout ReportItemViewModel.

    2. COPopup was something that I had thought about but I felt as if it would look out of place. About expander, well not sure how to implement it as I have multiple reports. Do you mean that for each report I have one expander in disabled/invisible mode and should be made enabled/visible based on report selection. Can you elaborate?

    3. COYou said you had your lists in a tab and not in the Main View because you want to preserve screen real-estate. I was saying that using an expander in your main view could provide you with enough room for the reports when collapsed, and then with enough room to add new reports when expanded.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
