public class TextBoxDecimalMaskingBehavior : TextBoxMaskingBehaviorBase, IAnimatable, IAttachedObject

Examples

The following example shows how to use the TextBoxDecimalMaskingBehavior to restrict entry of digits after the decimal to 2 and restrict the range from 0 to 100.

<StackPanel Orientation="Horizontal">
    <TextBlock Style="{SAF:Style TextBlockContentBoxLabel}"
               Text="Enter the percentage" />
    <TextBox Style="{SAF:Style TextBoxSingleLine}"
             Text="{Binding Percentage}"
             Width="150">
        <b:Interaction.Behaviors>
            <SAF:TextBoxDecimalMaskingBehavior NumberOfAllowedDecimalPoints="2" Minimum="0" Maximum="100" />
        </b:Interaction.Behaviors>
    </TextBox>
</StackPanel>
