In this article I am going to show AutoCompleteTextBox in WPF.
AutoCompleteTextBox mean
when we type something to search in a
textbox to get a small list of valid search results that match the search string
entered so far. In this article I am using Linq to Sql also. I have saved my
DataBase
inside DATA folder. To run the application just add this database and change
connection string from setting inside properties folder.
See in this image.

<Window x:Class="AutoCompleteTextBoxInWPF.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow"
Height="250" Width="350">
<Grid Background="AliceBlue">
<Grid.RowDefinitions>
<RowDefinition Height="40" />
<RowDefinition Height="203" />
</Grid.RowDefinitions>
<TextBlock Text="Search :" HorizontalAlignment="Left"
VerticalAlignment="Bottom"
Width="70"
Height="15.96"
Margin="31,0,0,4" />
<TextBox HorizontalAlignment="Right" VerticalAlignment="Bottom"
Height="25"
Width="160"
Margin="0,0,10,0"
x:Name="txtName"
TextWrapping="NoWrap"
SelectionChanged="txtName_SelectionChanged" />
<ListBox x:Name="listName" SelectionChanged="listName_SelectionChanged"
Background="LightCyan"
Grid.Row="1" Visibility="Collapsed"
HorizontalAlignment="Right"
VerticalAlignment="Top"

Margin="0,0,10,0"/>
</Grid>
</Window>
When we run the application and want to
search name which start with "R".

If we type character "E", then the textbox
