Input Scope of a TextBox defines the information related to the scope of the data provided by the input method and use to define the layout of the onscreen keyboard of the device. It is present in the "System.Windows.Input" namespace and exposed in TextBox as a property called "InputScope".
You might be wondering what is this property and why should one use it. Ok, let us discuss this in depth with a small sample. After reading this chapter, you will be able to understand it more and use it on your business requirement. Don't forget to share this tutorial links to others as this will help them to learn more.
InputScope is a property exposed by TextBox control of Windows Phone 7. It's a property of type InputScope and present in the namespace "System.Windows.Input" and inherits DependencyObject. InputScope takes parameter InputScopeName which is of type InputScopeNameValue.
Generally, this can be declared for TextBox similar way as shown in the below code snippet:
You can also reduce the no. of lines by specifying the value in this format:
This property represents the information related to the scope of the data provided by the input method. We will learn more about it in the next point with some sample code.
InputScopeNameValue is an enum type which represents the different way of text input pattern. It has a no. of enum values. Let's see the meta data of the enum here. Just read the comments in each line to know more about the enum values.

In this section, we will demonstrate some of the enum values of InputScope and check how it changes the onscreen keyboard of the device. Here we will discuss the following 6 input scope values:
Default Inputscope:
<TextBlock Text="Default: " FontSize="30"/>
<TextBox Width="450" Height="75" InputScope="Default"/>
<TextBlock Text="EmailSmtpAddress: " FontSize="30"/>
<TextBox Width="450" Height="75" InputScope="EmailSmtpAddress"/>
<TextBlock Text="Number: " FontSize="30"/>
<TextBox Width="450" Height="75" InputScope="Number"/>
<TextBlock Text="PostalCode: " FontSize="30"/>
<TextBox Width="450" Height="75" InputScope="PostalCode"/>
<TextBlock Text="TelephoneCountryCode: " FontSize="30"/>
<TextBox Width="450" Height="75" InputScope="TelephoneCountryCode"/>
<TextBlock Text="Time: " FontSize="30"/>
<TextBox Width="450" Height="75" InputScope="Time"/>
Here I demonstrated 6 different input scope examples. Change the input scope name value for the other types and see how your onscreen keyboard looks like inside the device. Hope this chapter was helpful for you to understand this property attribute. Use it properly in various cases while developing your application.
