PowerApps Tutorial: Passing Values Between Screens using Global Variables

 To pass a value from one screen to another in PowerApps, you can use a global variable or a context variable. Here's how you can achieve this:

1. Create a global variable:

   1. Open the PowerApps Studio and go to the screen where you want to pass the value from.
   2. Select "Insert" from the top menu and choose "Controls" > "Button" (or any other control you prefer).
   3. In the Properties pane on the right side, select the button, and under the "OnSelect" property, enter the following formula:
   • 
     

   • 
     Set(GlobalVariableName, "ValueToPass")
     

     Replace "GlobalVariableName" with the name you want to assign to the global variable, and "ValueToPass" with the actual value you want to pass.

2. Navigate to the target screen:

   1. Select the button you created in the previous step.
   2. In the Properties pane, under the "OnSelect" property, enter the following formula to navigate to the target screen:
   • 
     

     
     Navigate(TargetScreen, ScreenTransition.None)
     

     Replace "TargetScreen" with the name of the screen you want to navigate to.

3. Retrieve the value on the target screen:

   1. Go to the target screen.
   2. Add a label or any other control where you want to display the passed value.
   3. In the Properties pane, set the Text property of the control to the following formula:
   • 
     

   • GlobalVariableName
     

     Replace "GlobalVariableName" with the name of the global variable you created in step 1.

By following these steps, you can pass a value from one screen to another in PowerApps using a global variable. Remember to adjust the names and formulas according to your specific scenario.
