    <p><strong>EDIT</strong>: it appears this was just VisualStudio somehow getting confused. It accepted it just fine after restarting. I'm not seeing a way to close the question though.</p> <p>I have a window with two controls: a togglebutton and a textbox. I want the togglebutton to control the visibility of the textbox, namely, show the textbox when the togglebutton's ischecked property is true, and collapse the textbox when it is false (with an initial ischecked status of false).</p> <p>Based on the information I've been able to find, it seems like the following simple XAML should work:</p> <pre><code>&lt;Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"&gt; &lt;Window.Resources&gt; &lt;BooleanToVisibilityConverter x:Key="IsCheckedVisibilityConverter"/&gt; &lt;/Window.Resources&gt; &lt;StackPanel&gt; &lt;ToggleButton x:Name="ShowTextBox" Content="Show the TextBox" IsChecked="False"/&gt; &lt;TextBox Visibility="{Binding IsChecked, ElementName=ShowTextBox, Converter={StaticResource IsCheckedVisibilityConverter}}"/&gt; &lt;/StackPanel&gt; &lt;/Window&gt; </code></pre> <p>However, I am unable to compile and run this as I receive the error:</p> <pre><code>The TypeConverter for "IValueConverter" does not support converting from a string. </code></pre> <p>with a blue squiqqly underline underneath the portion [Visibility="{Binding].</p> <p>I'm sure I must be doing something wrong, but I've spent a few hours trying to find information as to why it's not working, and all I can find are examples showing this being the more-or-less correct way to do it. Can anyone point out what I'm doing wrong?</p> <p>I'm relatively new to C#/WPF/XAML, so I'm toying around with things to get a better feel for it all. If there's a control that's better suited for this task, I'm interested to know about it, but I'm more interested in how to get this working so I can better understand what's happening (or rather, why it's not working).</p> <p>Thank you.</p>

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.
