Complete task in canvas apps

[NurNina]

I use Task entity in my canvas apps. How can I make the task to Mark Complete or Close Task just like in model-driven apps?

In the Task entity you have a option set called Activity Status which you can use to open, Complete or cancel the task.

You can incorporate this in the form and you can save the status of the same by submitting the form data using button/Icon.

Follow the below steps to achieve the same on your end.

--> Insert a data table in power app and connect it to tasks entity, Once you connect it by default you will be able to see the fields Subject, Due date, Priority. To insert other fields you can click on fields option on the left hand side and insert the activity status column

--> Now you will be able to see activity status of all the tasks

--> Insert another screen in your app and insert a edit for in that screen connect it to tasks entity and follow the same process as above to insert activity status field in that form

--> set the form item property to Datatable name.selected.

--> Insert a button on screen 2 to submit the form data. 

Now you will be able to open, complete and cancel tasks as in model driven apps.

It's a great solution. Thanks. On another note, what is the difference between status reason and activity status? It seems that they both have the same items of option set.

@Krishna92 It seems @NurNina and I are working on similar projects - we have similar questions popping up.

I am having trouble completing a task from a canvas app, unless the user is a System Administrator.

I followed your instructions above, and if the 'Submit' is run by a user with the System Administrator role assigned, the Submit/Change to Completed is successful.

If the 'Submit' is run by a user with all roles except System Administrator, the following error is returned: "(12) The requested operation is invalid.  Server Response: Cannot update Closed or Cancelled Activity"

This error is returned when I select an open activity, change the Activity Status to 'Completed', and submit.

Can you help please?  Thank you!
