HighlightingTextBox

A custom textbox for WPF which will highlight text in a comma-separated list depending on a supplied function.

Usage

The dependency properties HighlightColor and ShouldHighlight should be specified.

For example, this will highlight in yellow the first and second items in this list when it is typed into the textbox: HIT, FOOHITBAR, MISS

FooView.xaml:

<Window x:Class="TestWpf.Views.TestView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:highlightingTextBox="clr-namespace:HighlightingTextBox;assembly=HighlightingTextBox"
        Title="TestView" Height="300" Width="300">
    <Grid>
        <highlightingTextBox:HighlightingTextBox x:Name="Test"
                                    ShouldHighlight="{Binding Matches}"
                                    HighlightColor="Yellow" />
    </Grid>
</Window>

FooViewModel.cs:

        public Func<string, bool> Matches
        {
            get { return x => x.Contains("HIT"); }
        }
