Body
I'm a week into learning visual basic and I'm completely stuck. I have a TabControl with 2 TabItems in the XAML of a WPF: <pre><code><TabControl Name="browser_tabs" Width="Auto" Height="Auto" BorderThickness="0"> <TabItem Header="My Page"> <DockPanel Name="tab1" Width="Auto" Height="Auto" Background="#fefefe" /> </TabItem> <TabItem Header="Browser" Name="browserTab"> <DockPanel Name="tab2" Width="Auto" Height="Auto" Background="#fefefe" /> </TabItem> </TabControl> </code></pre> and I am trying to change the tab (programmatically / problematically) from a class, bookmarkControlsObj, within the MainWindow class: <pre><code>Class MainWindow ... Public Class bookmarkControlsObj Public Sub follow(ByVal url As String) browser_tabs.selectedIndex = 1 '<--- ahhhhhhhhhhhhhhhhhhh!' web_view2.Load(url) End Sub End Class End Class </code></pre> But I keep getting "<code>Reference to a non-shared member requires an object reference.</code>" -- I have no idea how to share the XAML TabControl within the bookmarkControlsObj class.. and it's driving me crazy. Please help. EDIT: The reason I have a nested class is because I'm calling the "follow" Sub within the class from a cefsharp (chrome embedded) WebView housing a page with a Javascript function -- using the <code>RegisterJsObject</code> I'm able to call a vb.net method via Javascript. In this case I'm sending a url to the "follow" Sub which loads it in a browser contained in the second TabItem, but I want it to automatically switch to that tab before it loads -- Long story short, <code>RegisterJsObject</code> seems to only work if it is contained within a class.. though it's only nested because that's where it ended up. I'm able to access the browser in the second tab from the class because I declared it "shared" and added it to the TabItem -- but I'm not sure how to declare the TabControl (set visually) as Shared Here is a link to the RegisterJSObject if it helps any: <a href="https://github.com/ataranto/CefSharp/blob/master/CefSharp/CefSharp.h#L116" rel="nofollow">https://github.com/ataranto/CefSharp/blob/master/CefSharp/CefSharp.h#L116</a>

Guidance

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.
