When diving into the source code, I discovered the BackDrop control and immediately decided to give it a spin. The dynamic blur effect comes from a CompositionBrush that is applied to a SpriteVisual. So it applies to all pixels underneath the surface of its host control:. The main brush is a CompositionEffectBrush that combines not two but three effects. I modified the original code of the BackDrop control to expose all relevant parameters of its brush as dependency properties, so you can two-way-bind to these through XAML and C :.

Here are the PropertyChangedCallback delegates that update the effect parameters:.

The home page of my sample app allows you to play with all of the parameters. The main purpose of the BackDrop control is to be used as background for different panels, e.

This page demonstrates the impact of BackDrop control. To use a BackDrop, just put the control inside a transparent container:.

The control is in its own library, for easy reuse. You are commenting using your WordPress. You are commenting using your Google account. You are commenting using your Twitter account.

BlurAmount", "Color.First, when tabbing through controls in my ContentDialog with a UserControl as it's contentit seems to be skipping controls that should be next on the tab index. Second, let's say I have a TextBox that currently has focus, if a user presses Left on the keyboard, when they are already at the beginning of the TextBox, it will change focus to the page currently behind the ContentDialog.

I did some tests with the code you posted, but I can't reproduce your problem. Everything seems just fine in my side. Following is the code I've used to test. So could you please share a simple sample so that we can reproduce your problem. And also you can test my code to see if the problem still there. I also recreated a simple sample using your UserControl with ContentDialog, as Jay Zuo said, It worked well, are you sure that there is no additional code to affect the Tab navigation?

I'm writing an app for the universal windows platform using the dark theme and I've noticed that although I've correctly set the requested theme to dark when I display a modal dialog using the ContentDialog class the overlay lightens the overall page rather than darkening it.

Since there isn't a property on ContentDialog to control the overlay how do I override the colour being used? By inspecting the default theme definitions it emerges that both light and dark themes set this brush to the colour resource SystemBaseMediumColor which on the light theme is and on the dark theme is 99FFFFFF.

This results in the overlay darkening the light theme and lightening the dark theme.

Since SystemBaseMediumColor is references by other brush definitions such as those used for inactive pivot titles it's necessary to override SystemControlPageBackgroundBaseMediumBrush rather than the colour it references solely for the dark theme. To do this we need to redefine the brush in a resource theme dictionary in App. I used the code for the accepted answer, but changing the color of this brush worked for me Also make sure your resource dictionary key matches the theme you are using.

I was using the "Light" theme, so I changed the Resource dictionary x:key to this Here, "this" represent the Content Dialog reference or you can pass the object reference of the ContectDialog.

Stack Overflow works best with JavaScript enabled.The dialogs and flyouts guidance learns us that dialogs are UI overlays that provide contextual app information and block interaction with the app window until they are explicitly dismissed. That makes them different from Flyouts, Tooltips or Toast Notifications, which are easily dismissed or even close automatically.

Dialogs are typically used in the following scenarios, and these are exactly the views that are exposed by the ModalView service:. Basically we need a control to display some text sone, two, or three buttons, an optional input field, and an overlay to cover the app window to make it inaccessible. By the way: try to get rid of the old Windows 8 MessageDialog. When the app window becomes too small in height or width, the ContentDialog automagically snaps to the sides, like this:.

It also shows how to create a multi-line title:. To transform a content dialog into an input dialog, it suffices to replace the default text Content by an input control, such as a TextBox. The ModalView Service provides two input dialogs: one for a string value, and one for a larger text value. Feel free to add your own versions to request for a number, a date, or a selection from a list.

You can provide a default value for the response, and we will place the caret at the end through SelectionStart :. The InputTextDialogAsync method listens for a possibly longer text input, and looks very similar to the previous one. The input TextBox is higher, accepts line feeds, and does TextWrapping :.

TextWrapping an exception is thrown. You can guess what my first assignment was…. Did you observe that I slightly pimped the default style of the ContentDialog?

To add some contrast —and to get rid of the default AccentColor — I applied a custom BorderBrush to the dialog itself and to the input TextBoxes. Here are the upgraded parts:. Be aware: if you retemplate built-in controls you have to closely follow up and verify your styles against all the new SDK-releases.

Future native ContentDialogs may have a different structure or visual states, or will make use of new features like the AcrylicBrush for the overlay or RevealBrush on the button s.

They block interactions with the app window until being explicitly dismissed. They often request some kind of action from the user. Windows UI Library 2. For more info, see Corner radius.

For more info, including installation instructions, see Windows UI Library. Use dialogs to notify users of important information or to request confirmation or additional info before an action can be completed.

For recommendations on when to use a dialog vs. To create a dialog, you use the ContentDialog class. You can create a dialog in code or markup. Although its usually easier to define UI elements in XAML, in the case of a simple dialog, it's actually easier to just use code. This example creates a dialog to notify the user that there's no WiFi connection, and then uses the ShowAsync method to display it. When the user clicks a dialog button, the ShowAsync method returns a ContentDialogResult to let you know which button the user clicks.

The dialog in this example asks a question and uses the returned ContentDialogResult to determine the user's response. Because dialogs block user interaction, and because buttons are the primary mechanism for users to dismiss the dialog, ensure that your dialog contains at least one "safe" and nondestructive button such as "Close" or "Got it!

All dialogs should contain at least one safe action button to close the dialog. This ensures that the user can confidently close the dialog without performing an action.

When dialogs are used to display a blocking question, your dialog should present the user with action buttons related to the question. The "safe" and nondestructive button may be accompanied by one or two "do it" action buttons. Three button dialogs are used when you present the user with two "do it" actions and a "don't do it" action. ContentDialog has three different types of buttons that you can use to build a dialog experience. Using the built-in buttons will position the buttons appropriately, ensure that they correctly respond to keyboard events, ensure that the command area remains visible even when the on-screen keyboard is up, and will make the dialog look consistent with other dialogs.

Every dialog should contain a safe, nondestructive action button that enables the user to confidently exit the dialog. Use the ContentDialog. CloseButton API to create this button.

This allows you to create the right user experience for all inputs including mouse, keyboard, touch, and gamepad.

This experience will happen when:. In addition to the CloseButton, you may optionally present the user with one or two action buttons related to the main instruction. Leverage PrimaryButton for the first "do it" action, and SecondaryButton for the second "do it" action.

In three-button dialogs, the PrimaryButton generally represents the affirmative "do it" action, while the SecondaryButton generally represents a neutral or secondary "do it" action.

For example, an app may prompt the user to subscribe to a service. The PrimaryButton as the affirmative "do it" action would host the Subscribe text, while the SecondaryButton as the neutral "do it" action would host the Try it text.

The CloseButton would allow the user to cancel without performing either action. You may optionally choose to differentiate one of the three buttons as the default button. Specifying the default button causes the following to happen:.
