WPF Tips: 高亮显示在listbox中第一个与textbox内容匹配的项

在textbox中输入内容，同时在listbox中高亮以目前textbox内容开头的项。

 

public String SearchText
{
get;
set;
}

public Window_Selection()
        {
            InitializeComponent();
            InitBinding();
        }

        private void InitBinding()
        {
            this.ListBox.ItemsSource = Executor.MyList;
            this.TextBox_Name.DataContext = this;
        }

private void TextBox_Name_TextChanged(object sender, TextChangedEventArgs e)
        {
            //search in listbox, SearchText
            DoSearch(this.TextBox_Name.Text);
        }

        private void DoSearch(string text)
        {
            this.ListBox.SelectedValue = Executor.MyList
                .Find(p => p.StartsWith(text,StringComparison.OrdinalIgnoreCase));
            this.ListBox.ScrollIntoView(this.ListBox.SelectedValue);//使listbox滚动到高亮项
        }

 

<TextBox x:Name="TextBox_Name" Grid.Row="1" VerticalAlignment="Top" HorizontalAlignment="Stretch" Text="{Binding Path=SearchText}" TextChanged="TextBox_Name_TextChanged"/>
