#PowerPlatformTip 85: 'Delay Output'

TL;DR: Enable Delay Output on TextInput controls so updates fire only after the user stops typing, cutting data traffic and boosting app responsiveness.

💡 Challenge

Immediate data updates with every user input can slow down your app and overload your data sources.

✅ Solution

Implement Delay Output in TextInput fields to improve app performance and reduce unnecessary data traffic.

🔧 How It’s Done

Here’s how to do it:

  1. Enable Delay Output on the control.
    🔸 Set the DelayOutput property of the TextInput to true.
  2. Understand the effect.
    🔸 Updates and calculations are only made after the user has finished typing, not with each character entered.

🎉 Result

Enjoy a faster, more responsive app with optimized data handling.

🌟 Key Advantages

🔸 Improved Performance: Delays in data processing lead to a smoother user experience.

🔸 Reduced Load: Lessens the number of requests to your data sources, preserving resources.

🔸 Efficient Data Traffic: Minimizes network traffic, leading to quicker app responses.

🛠️ FAQ

1. What does the Delay Output property do?

The Delay Output property postpones data updates until the user has paused typing, preventing updates on every keystroke.

2. How do I enable Delay Output in my app?

Go to the TextInput control’s properties and set DelayOutput to true to defer updates until typing pauses.

3. Will delaying output impact data accuracy?

No, Delay Output only optimizes when updates fire; final input values are still captured correctly upon submission.

4. Is there a Wait() or Sleep() function in Power Apps?

No. Power Fx rejects both: Wait(1) and Sleep(1000) fail with unknown or unsupported function. DelayOutput is a property of the Text input control, not a function. To run a formula after a fixed delay, use a Timer control: set Duration in milliseconds and put the formula in OnTimerEnd.
