WPFTextBoxAutoComplete

An attached behavior for WPF's TextBox control that provides auto-completion suggestions from a given collection

How to use this library:

  1. Install the package via NuGet

    	PM> Install-Package WPFTextBoxAutoComplete

  2. Add a reference to the library in your view

    	xmlns:behaviors="clr-namespace:WPFTextBoxAutoComplete;assembly=WPFTextBoxAutoComplete"

  3. Create a textbox and bind the "AutoCompleteItemsSource" to a collection of IEnumerable<String>

    	<TextBox 
		Width="250"
		HorizontalAlignment="Center"
		Text="{Binding TestText, UpdateSourceTrigger=PropertyChanged}" 
		behaviors:AutoCompleteBehavior.AutoCompleteItemsSource="{Binding TestItems}" 
	/>

  4. (Optional) Set the "AutoCompleteStringComparison" property, which is of type StringComparison

    	<TextBox 
		Width="250"
		HorizontalAlignment="Center"
		Text="{Binding TestText, UpdateSourceTrigger=PropertyChanged}" 
		behaviors:AutoCompleteBehavior.AutoCompleteItemsSource="{Binding TestItems}" 
		behaviors:AutoCompleteBehavior.AutoCompleteStringComparison="InvariantCultureIgnoreCase"
	/>

  5. (Optional) Set the "AutoCompleteIndicator" property, which is a String. This is used to indicate to the behavior that it should start making auto-completion suggestions.

    	<TextBox 
		Width="250"
		HorizontalAlignment="Center"
		Text="{Binding TestText, UpdateSourceTrigger=PropertyChanged}" 
		behaviors:AutoCompleteBehavior.AutoCompleteItemsSource="{Binding TestItems}" 
		behaviors:AutoCompleteBehavior.AutoCompleteIndicator="@"
	/>

Now, every time the "TestText" property of your datacontext is changed, WPFTextBoxAutoComplete will provide you with auto-completion suggestions. To accept a suggestion, just hit "enter".
