As my thoughts build to initiate writing this blog, similar was the feeling when I first thought about exploring Power Apps. The expression was, “What exactly is Power Apps?”. When the world is talking about it, it brings me more curiosity to understand what is so powerful about it.
Let’s first commence with understanding what exactly is Power Apps:
Types of Power Apps:
In this blog we shall focus more on how to make a Canvas app. Follow the steps below to make a PowerApps.
Login to www.portal.office.com
Click on PowerApps icon as shown in the image below:
This will open a new browser tab where we need to select what kind of app do we need to make.
Click on Canvas app from blank, which opens a pop up. Please name your app and select whether the app is for Phone or for Tablet as shown below and click on Create button.
This opens the Canvas app editor as shown below:
To take this blog forward, I will use an app that is created by me and explain a few commands used by me and how was the design done in that app.
The app captures the Grievances of people in office.
There are 5 screens created by me and they are:
Let’s take a dive in each screen and get into understanding of functionalities developed on each screen:
There are approximately more than 250 Data sources to which Power apps can connect. Select the data source you wish to connect. In my case, I will connect to Dynamics 365 Data Source.
It will ask you to choose your entity and then you can click on connect.
Your Data Source “Grievances” will start appearing in Items drop down of Property Window.
Post that we can align the attributes that we need to see on the list view:
To Display Employee Full Name, below is the code that i wrote:
ThisItem.’Employee Full Name’
To get the department value, which is a lookup to another entity below is the code that was written
To display the image from the SharePoint Library, below is the code:
LookUp(GrievanceLibrary, Title = TitleGrievance.Text, Image)
Where GrievanceLibrary is the Sharepoint Datasource added in Powerapp and Title and image are the fields created in SharePoint.
To open the Grievance record on frm_Grievance Record, write the below code:
To store the new grievance record, we used the Form Screen.
On the update button, write the below code:
Insert a Camera Media Control on the form as shown in the below screen shot.
Insert an image control on the form below the Camera Media control.
Capture button code:
Collection 1 s described above is the SharePoint collection object which needs to be cleared and then referred with the new Photo from the Camera Control, which in our case is Camera1.
Confirm button code:
Confirm Button will only Navigate it to New Grievance form and the code is ass per below:
This blog reflects my personal findings and based solely on my experience of using Power Apps.
