TL;DR: Reset every Power Apps control at once by binding their Reset property to a single context variable and toggling it with
UpdateContext({ResetVar: !ResetVar}).
💡 Challenge
In Power Apps, resetting multiple controls to their default state is tedious if you reset each control individually with the Reset function. It makes the app less efficient and clutters your code with repetitive statements.
✅ Solution
Reset all controls at once using a single context variable. Link every control’s Reset property to that variable, then toggle the variable to reset them globally, saving time and keeping your code clean.
🔧 How It’s Done
Here’s how to do it:
1. Create a context variable
🔸 Initialize a context variable, e.g. ResetVar, in the app’s OnStart or the screen’s OnVisible property.
2. Link your controls
🔸 Set the Reset property of every control you want to reset to ResetVar.
3. Trigger the reset
🔸 Toggle the variable from a button’s OnSelect: UpdateContext({ResetVar: !ResetVar}).
🎉 Result
You can reset all linked controls globally with a single action, making your app more efficient and your code cleaner.
⚠️ Important Note: Test the reset thoroughly to confirm all controls return to their expected default values.
🌟 Key Advantages
🔸 Efficiency: Reset all controls with one action instead of coding individual reset functions.
🔸 Cleaner Code: Avoid repetitive reset statements for a more maintainable app.
🔸 User Experience: Deliver a quick, seamless reset for better usability.

1. How do I initialize the ResetVar?
Set it in a screen’s OnVisible property or the app’s OnStart using UpdateContext or Set.
2. Can I reset only a subset of controls?
Yes. Link only the controls you want to reset by setting their Reset property to ResetVar.
3. What if a control doesn’t reset as expected?
Ensure its Reset property is correctly bound to ResetVar and that you’re toggling the variable in your action’s OnSelect.
