COLORPICKER PICTURE HOW TO

This example shows how to configure the color picker with a simple UI for "casual" use. In this example, you enable an opacity slider and textbox on the color picker. You should consider the circle spectrum as more of the "casual" color choosing experience. A user has more control when they select a specific color using a square because more of the color gamut is shown. When you must choose between the square and circle color spectrum, a primary consideration is accuracy. This example shows how to use the ColorSpectrumShape property to configure the color picker to use a circular spectrum instead of the default square. When the user does need precise control, like in a graphic design app, you can show both sliders and text entry fields for each aspect of the color. You can hide the text entry fields and change the color spectrum to a circle. It provides a variety of options that let you configure the control to fit your needs.įor example, when the user doesn't need precise control, like picking a highlighter color in a note taking app, you can use a simplified UI. Not all fields are necessary to let a user pick a color, so the color picker is flexible. Private void cancelColor_Click(object sender, RoutedEventArgs e) Assign the selected color to a variable to use outside the popup. Private void confirmColor_Click(object sender, RoutedEventArgs e) When the user confirms their color choice, you save the selected color to use later in your app. In this example, you host a color picker in a Flyout with Confirm and Cancel buttons. You can also save the selected color value to use later. For example, when you host a color picker in a flyout, we recommend that you apply the selected color only after the user confirms the selection or closes the flyout. In some cases, you don't want to apply the color change immediately. See the Customize the color picker section for more info. When the color change can be seen and happens in real-time on the affected object, you don't need to show the color preview bar. This example uses a simplified color picker with just the circle and the slider, which is a common "casual" color picking experience. Any change to the color picker results in a live change to the bound property. In this example, you bind the Color property of a SolidColorBrush that's used as the Fill for a Rectangle directly to the color picker's selected color.

When the color selection should take effect immediately, you can either use databinding to bind to the Color property, or handle the ColorChanged event to access the selected color in your code. See the following examples for detailed code.

You can use either the ColorChanged event or the Color property to access the selected color and use it in your app. īy default, the color picker shows a preview of the chosen color on the rectangular bar beside the color spectrum. This example shows how to create a default color picker in XAML.

Get the app from the Microsoft Store or get the source code on GitHub The WinUI 3 Gallery app includes interactive examples of most WinUI 3 controls, features, and functionality. Open the WinUI 3 Gallery app and see the ColorPicker in action.

Or, commit the selection upon dismissing the flyout, by either tapping outside of the flyout or hitting the back button.

Hitting the back button or tapping outside of the flyout will dismiss it, and not save the user's selection.

Provide commit and cancel buttons to apply or cancel the selection.

When used in a flyout, tapping in the spectrum or adjusting the slider alone should not commit the color selection.

For the most accurate color picking experience, use the square spectrum and ensure it is at least 256x256px, or include the text input fields to let users refine their selected color.

Some scenarios may not require granular color picking and would benefit from a simplified picker

Think about what kind of color picking experience is appropriate for your app.

If your app is for drawing or similar tasks using pen, consider using Inking controls along with the color picker. For example, use it to change color settings, such as font colors, background, or app theme colors. Use the color picker to let a user select colors in your app. By default, it lets a user navigate through colors on a color spectrum, or specify a color in either Red-Green-Blue (RGB), Hue-Saturation-Value (HSV), or Hexadecimal text boxes. A color picker is used to browse through and select colors.
