WPF - Show/Hide element based on CheckBox.Checked

December 10, 2007 · 1 min read

A lot of times, I need to show or hide a textbox based the value of a checkbox. 

unchecked

checked

In WinForms 2.0.  This was easy:

With the new Visibility Enum in WPF, this becomes a bit trickier.  To accomplish this, you need to implement a converter that will accept a boolean value and return a visibility value.  The converter I used is here:

The XAML code to use this is below.  The important parts are:
xmlns:converters="clr-namespace:ParaPara.Converters"
converters:BooleanToHiddenVisibility x:Key="boolToVis"
TextBox ... Visibility={Binding Path=IsChecked, ElementName=checkViewTextBox...}"

Now we can cleanly show or hide an element based on a checkbox using just XAML code.
