Build Powerapp from the scratch


Go to https://create.powerapps.com/ and authenticate

Select a blank app to start it from the scratch


Establish connection

Go to ribbon and select content->Data Source




 Then it will list the available services click SharePoint and enter URL then click GO







Then select your SharePoint List you want to use (My case ‘Reviews Demo’)


Select the list and click connect. Now datasource will be created in powerapp


Design screen


Select Screen layout

Set Title

Add image control

Format the title






Design list view

Now click on the first item in the screen and modify it as needed 
Note: Remember what ever change we do for the first item would reflects to all other items

Data mapping


One of the best feature in powerapp is automatic data mapping. It's easy & straight forward




  • Step 1: Select the control. 
  • Step 2: Choose "Items" from the drop-down. 
  • Step 3: Enter data source name("Reviews Demo") in my case.Note: By this time you will see minor '!' don't PANIC we are yet to complete the mapping.

Click on the '!' symbol it will take you to the error control

In this case i don't have a field called "body" in my datasource. so now i will change it to "Review description" column


Configure user picture


Select the image control


Go to the formula bar and enter the below function()
User().Image
User function has the below properties of currently authenticated user


Select Image as a picture source

Note: There are many inbuilt functions available please refer here for more

Run the application



 Final output


Save & Configure

Click File-> Save

you can choose your option to save the app

Click ->App settings and configure your app logo and kinds of stuff..

Click on Screen size + orientation

to configure the respective settings and click "Apply" to save it.

Sharing the app


Go to https://web.powerapps.com/ and authenticate




There are 2 types are permissions
1. User - can only view and modify. 
2. Can edit the app and can provide access to others.

Version control



 Note: It's always good to have few stable versions in just to avoid the confusion. As still there is no custom comment field available to remember our stable version.

Share it with the site users

Click "Apps" from the left menu

Click "Details" icon
So in this Series(1/3) we saw how to create an powerapps from the scratch
on the upcoming series will Add some interaction to the app

Step-By-Step Azure AD App Registration

Image
Enterprise developers and software-as-a-service (SaaS) providers can develop commercial cloud services or line-of-business applications, that can be integrated with Azure Active Directory (Azure AD) to provide secure sign-in and authorization for their services. To integrate an application or service with Azure AD, a developer must first register the application with Azure AD. Any application that wants to use the capabilities of Azure AD must first be registered in an Azure AD tenant. This registration process involves giving Azure AD details about your application, such as the URL where it’s located, the URL to send replies after a user is authenticated, the URI that identifies the app, and so on.  In the upcoming series of articles will see different 'grant_type' and which one to use for what scenario? how to use in Daemon-Headless-App calling secure WebAPI - client_credentials/password_credentials how to use in Windows-Forms-App calling secure WebAPI - code_credentia
