How to Disable Button as a component Based on Timer Component within a Behaviour Custom Function

I currently have a button component called in one of my screens.

I would like this button to be disabled for 40 seconds after it is clicked. Once the 40 seconds are up, it should be enabled, and if clicked again, it should be disabled for 40 seconds again. 

 

I have tried following the solution in this forum post but to no avail since "UpdateContext is unknown or unsupported function."

 

Any tips on how this may be tackled please? 

 

Thanks in advance!

It is no longer showing as disabled, but now when I click it, it is still enabled. 

 

I managed to get it to work by doing the following (as you suggested):

 

In the timer control set duration to 40 seconds.
In the timer control added this to the OnTimerStart: Set(disableBtn, true)

In the timer control added this to the OnTimerEnd: Set(disableBtn, false)

In the display mode property added this: If(disableBtn, DisplayMode.Disabled, DisplayMode.Edit)

 

However, I also had to set Start to disableBtn, and in the onSelect of the button function, I set disableBtn to true. That way the timer starts on disableBtn=true.

 

Thanks for your help!

Please share your code and I can help.

OnSelect code (in component) 

testing.Function1(var1, var2, var3);
testing.Function2();

The component contains Function 1 and Function 2 which are used to create collections. They are behavior functions. 

Function 1: 

Clear(Temp);
ForAll(Filter(A,id=rowId),//gets row from costmodel collection 
ForAll(Split(Substitute(Substitute(JSON(ThisRecord,JSONFormat.IgnoreBinaryData),"{",""),"}",""),","),//uses JSON object to convert it to a column
Collect(Temp,Split(Result,":").Result)));//stores the result in a collection
Collect(Temp2,
{
   //adding row data, using data passed as parameters and data from the column created from the row
});

Function 2: 

ClearCollect(B, Temp2);

 

I tried to create a Timer within the component, setting its visibility to False behind the button. Then from the button, after calling functions 1 and 2, I tried calling 

UpdateContext({start:true});UpdateContext({var4:false}) 

but the UpdateContext is unknown or unsupported function." error message was output. Also, I would not know where to define the start and var4 variables. 

So on the time start you want to updatecontext to set it to false then on time end set this updatecontext to true. Then set the displaymode property of the button to the update context variable.  

Yes initially the component will be enabled. Once clicked, it should be disabled and after 40 seconds it should be enabled again. Not sure how this would be implemented exactly as I am new to development using Power Apps.

Ok try this. Add a timer control. For now we will use a global variable.

In the timer control set duration to your 40 seconds.
In the timer control add this to the OnTimerStart: Set(disableBtn, true)

In the timer control add this to the OnTimerEnd: Set(disableBtn, false)

In the button in the display mode property add this: If(disableBtn, displaymode.edit, displaymode.disabled)

I have added this code. The button is just permanently disabled

got my logic wrong way round, change to this:

 

If(disableBtn, displaymode.disabled, displaymode.edit)

Hello,

 

On a side note: "UpdateContext()" cannot be used inside a component. If you want to setup variables inside a component, you must use "Set()" which ironically defines variables which can only be accessed by the component itself.

It is no longer showing as disabled, but now when I click it, it is still enabled. 

 

I managed to get it to work by doing the following (as you suggested):

 

In the timer control set duration to 40 seconds.
In the timer control added this to the OnTimerStart: Set(disableBtn, true)

In the timer control added this to the OnTimerEnd: Set(disableBtn, false)

In the display mode property added this: If(disableBtn, DisplayMode.Disabled, DisplayMode.Edit)

 

However, I also had to set Start to disableBtn, and in the onSelect of the button function, I set disableBtn to true. That way the timer starts on disableBtn=true.

 

Thanks for your help!
