How to Disable Focus Visual Effects on TextBox in UWP Applications

When developing applications using Universal Windows Platform (UWP), you might encounter situations where the default focus visual effects on controls, like TextBox, can disrupt your application's aesthetic. If you're creating a UserControl that includes a Combobox and TextBox inside a grid, you might prefer to keep the design clean by removing these visual effects. This guide will address how to effectively disable focus visual effects on a TextBox.

Understanding the Problem

By default, a TextBox in UWP has focus visual indicators that help users identify which control is currently active. While these focus visuals enhance usability, there are times when they may be perceived as clutter, especially if your design emphasizes minimalism.

In your case, you want the borders of the TextBox to be the only visible elements to maintain a streamlined look. Let's explore how you can achieve this with a few simple steps.

Solution Overview

To disable the focus visual effects on a TextBox in UWP, you can modify the TextBox template. Follow these straightforward steps:

Step 1: Edit the TextBox Template

Open your UWP project in Visual Studio.

Switch to Design Mode.

Right-click on the TextBox you want to modify.

Select Edit Template - Edit a Copy. This creates a copy of the default template in your XAML.

Step 2: Modify the VisualState

After copying the template, navigate through the XAML code to modify the visual state to remove the focus visuals. Here's how:

Locate the VisualStateManager.VisualStateGroups section in your newly created template.

Comment out or remove the Focused visual state to prevent any visual indication when the TextBox is focused.

For example, you can change:

To:

Step 3: Finalize the Template

Wrap up your modifications by ensuring all other states (like Normal, PointerOver, and Pressed) remain intact unless you want to customize them too.

Here’s a simplified example of what a customized TextBox might look like:

Conclusion

By following these steps, you should now have a TextBox without any focus visual effects, aligning perfectly with a clean and modern interface design. Remember that customizing templates may require some testing to ensure that accessibility is not compromised for users who navigate with keyboards.

Additional Tips

Always test your changes on multiple devices or emulators.

Consider providing alternative cues for focus, like changing border colors or using sound feedback for accessibility.

By mastering these simple template modifications, you can greatly enhance the visual coherence of your UWP applications. Happy coding!
