I am trying to make modal dialog window for let user know some error messages, or let user edit some values. I am using MVVM pattern, so my mainwindow has some control part and workspace part. In workspace part, i am opening viewmodels tight with datatemplate to views (defined as usercontrols). From one of these views i want to open modal dialog window. I was following this answer <a href="https://stackoverflow.com/questions/1321346/error-window-show-modal-in-mvvm-wpf/1329785#1329785">Error window show modal in MVVM WPF</a>. As described in that answer, i have implemented the DialogClass in an InvoiceViewModel. But i have problem with showing the content of the modal window. If I set the content of the window to ViewModel class, output is simple text with namespace path to that ViewModel. (ViewModel attached to the View with datatemplate.) If I set content to the View - it is working - view is showed but, i am disobeing MVVM pattern (opening View from ViewModel as ViewModel has no reference to View). <pre><code> ErrorViewModel newErrorViewModel = new ErrorViewModel(); ErrorView newErrorView = new ErrorView(); DialogWindow dialogWindow = new DialogWindow(); //Not Working //dialogWindow.Content = newErrorViewModel; //Working But, breaking MVVM dialogWindow.Content = newErrorView; dialogWindow.ShowDialog(); </code></pre> In ErrorView.xaml i have attached ErrorViewModel like this. <pre><code><DataTemplate DataType="{x:Type vm:ErrorViewModel}"> <vw:ErrorView/> </DataTemplate> </code></pre> What am i doing wrong? Thanks.

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.
