WPF user control with a property of type Enum

Question

I have a usercontrol called "InputSensitiveTextBox" that inherits from Textbox. It has a property I define called "CurrentInputType", which is of type "MyControlsNamespace.SupportedInputTypes" (with values Keyboard, Mouse, Touchpad, VirtualKey). I need to have this property be set in Xaml just like I might set "HorizontalAlignment" or "ScrollbarVisibility" as such:

MyControlsNamepsace.InputSensitiveTextBox Background="Black" CurrentInputType="Keyboard"

Please advise :)

Answer 1

Is your CurrentInputType a dependency property?

If not here is the code for it to replace your old property:

public SupportedInputTypes CurrentInputType
{
    get { return (SupportedInputTypes)GetValue(CurrentInputTypeProperty); }
    set { SetValue(CurrentInputTypeProperty, value); }
}

// Using a DependencyProperty as the backing store for CurrentInputType.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty CurrentInputTypeProperty =
    DependencyProperty.Register("CurrentInputType", typeof(SupportedInputTypes), typeof(InputSensitiveTextBox), new PropertyMetadata(SupportedInputTypes.Keyboard));

In the PropertyMetadata you define your default..

Hope this fixes your problem!

You need to use the Static markup extenstion to reference your enumeration in xaml, You also need to add it's namespace to your namespace declarations.

xmlns:MyControlsNamepsace ="clr-namespace:MyControlsNamepsace"

<MyControlsNamepsace:InputSensitiveTextBox 
    CurrentInputType="{x:Static MyControlsNamepsace:SupportedInputTypes.Keyboard}"
    />
