Components and Buttons

[3ation]

Hi guys, 

We are developing a Menu components, but the menu items HAVE to do some current screen clean-up, and some next screen clean up, so the Components can't just navigate to next screen. Or sometimes, just take action on the current screen.

What is the best way to pass a "Set of Code" to be executed? We tried a button, but we cannot call Select (ThisItem.MyButton) on the components .  Is there a way to bascially either have a call back from the component, or if the component output var changed, to get a call back, or even activate a button on selelct....etc.? Only way so far is the ugly Timer system! Thanks in Advance

Hi @3ation ,

Could you tell me:

Do you have a button control in the component?

Do you want to switch to another screen after pressing the button?

If my assumptions are correct and you want to use the select() function in a component, I am afraid it is difficult to implement.

The select() function in the component cannot call controls outside the component.

At my knowledge, you could try the following steps to switch screens:

1\ Set a variable in the component.

2\ Set an output custom property.

3\ Add a timer control to continuously judge the output result. Once the variable value in the component is changed, the timer control executes the navigate() function to switch the screen.

I've made a test for your reference:

1\ Insert into a button control and set its onselect property to:

Set(A,true)

2\ Build an output custom property in a component :

3\ Set the custom property “Test” to:

A

4\ Set component’s onreset property to:         

Set(A,false)                                               Reset the value of the variable

5\ Add a timer control and set its OntimerEnd property to:

If(Component1_1.Test= true,Navigate(Screen2);Reset(Component1_1))

Set other properties of timer control.

If you still have any question, please don't hesitate to let me know.

HI @v-xiaochen-msft 

We have a timer, And we are doing all the code inside the timer effectively, the time is big switch of Which menu item is selected, and we do the code there,  We wanted to Select (Button) so that we have the code neat, but as you said, it can not be done!.   Switching screens, really should be the task of the Screens that calling the component (clean up data, Set initialization of Data, then Navigate). Not sure any of our 40 + Apps, just navigate!.  Thanks for your response... Timer is the only way it seems.
