How to start a timer control at a preset time

[cardinalnight]

Scenario:

1. The user will start the timer, Save the form and the time will save as milliseconds into a SharePoint text column.
2. The user will re-enter the form and the time from sharepoint will set the timer to what time was stored in SharePoint.

Problem:

The timer won't start because I've edited the Text property of the Timer:

If(IsBlank(varTime),
Text(Time(0, 0, Self.Value/1000), "hh:mm:ss"),
Text(Time(0, 0, varTime/1000), "hh:mm:ss"))

Is there a proper way to set the timer?
Note: I've seen suggestions using UpdateContext but this doesn't make sense or is any need to use a local variable in this scenario.

Also the user will start the timer by clicking on it and stopping it also, not by separate buttons.

Hope you can help.

Hi,

Try this method 

this code will patch the start time

Set(varNewitem,Patch('Time Tracking App',Defaults('Time Tracking App'),{Title:User().Email,Project:DataCardValue12.Selected,'Start Time ':Now(),'Active Session': true }));
UpdateContext({startTimer1:true});

This code will Patch End time 

Set(varNewitem,Patch('Time Tracking App',LookUp('Time Tracking App',varNewitem.ID=ID),{'Active Session':false,'End Time ':Now(),'Total Time Spend':DateDiff(varNewitem.'Start Time ',Now(),TimeUnit.Minutes)}));
UpdateContext({startTimer1:false});
Notify("Session Ended Successfully",NotificationType.Success);

@Ali_Sheraz_77 Thanks for your response, but that doesn't answer my question. You answer suggest something different.

Hi, @cardinalnight

Basically text property is used to show current value of timer 

To set the timer use this code on OnSelect property of timer

// In the OnSelect property of the Timer control
UpdateContext({varTimerRunning: !varTimerRunning})

And use variable Name(varTimerRunning) on Start property of timer 

and use this code on Duration property of timer 

// Duration property of the Timer (assuming varTime is set when the form/screen is loaded)
varTime

and use this code on OnTimerEnd

// The OnTimerEnd property of the Timer to save the elapsed time when the timer runs out
Patch(YourDataSource, YourRecord, {'SharePointColumn': Text(TimerControl.Value)})

adjust code according to your SP list

@Ali_Sheraz_77 - still not working sorry. I have implemented your code above and when I click on the timer control, it does not start at all.

Hi Ali,

First, thank you for your patience and consistence.

Here is the set up (how the column is brought into the app):

With(
    {
        wCaseRecord: LookUp(
            collExistingCases,
            ID = varSelectedCase
        )
    },
    Set(
        varTime,
        wCaseRecord.Time
    );
);

The SharePoint column is a single line text column.

The below shows each control in bold and the properties set below the control:

Timer1 - 

Duration: varTime

OnSelect: UpdateContext({varTimerRunning: !varTimerRunning})

Text: Text(Time(0, 0, Self.Value/1000), "hh:mm:ss")

Save Changes Btn - 

OnSelect:
Patch(
    OnGoingCases,
    LookUp(
        OnGoingCases,
        ID = varActualCase
    ),
    {
       
        Time: Text(Timer1.Value),
      
    },
    MyNotesAttachmentsForm.Updates
);

This provides no errors, but the timer doesn't start at all when clicked on.

I made a new timer (to see if the existing timer was corrupt) and it started when clicked on, but soon as I replaced the Duration property with varTime, it didn't start when clicked on.
