In this blog post we’ll explore how introducing a collection to our scanning approach can easily allow us to build our own ‘reset’ functionality for the Barcode Reader control.

I recently came across the following scenario posted on the forums and I moved my response to this blog.

Scenario:

When a user selects a record from a Gallery control, an Edit Form is automatically populated with the selected record. The user wants to be able to copy the existing record, make a change to one or more fields, and then submit the Form as a new record.

A login screen acts as a barrier between the content of your application and unauthorized users.

with the help of logging screen, you can have control on access and sensitive information and maintain integrity of application by making users to authenticate them.

Let’s get started with creating a login screen in PowerApps.

Step 1: Create a New App

Log in to PowerApps and navigate to the 'Apps' section.

Click on 'Create an app' and choose the 'Canvas app from blank' option.

Step 2: Design the User Interface

Once the new app is created, you can open the app using PowerApps Studio.

Design the login screen interface by adding two input fields for ‘Email id and ‘Password along with a ‘Login’ and ‘Register’ buttons.

You can add two text labels to text input boxes as shown in below screen.

Step 3: Connect to Data Source

Go to the ‘View’ tab and click on ‘Data sources’ à Add data and search for SharePoint, then click on Add a connection as shown in below screens.

Once connection is added you can able to find data source.

Step 4: Validate User Credentials

Double-click on the ‘Login’ button to open the formula bar.

Use the Lookup function to check if the entered username and password exist in your data source. The formula might look like:

If(!IsBlank(LookUp(EmployeeList, Email= TextInput1.Text And Password=TextInput2.Text).Title),Navigate(View_Screen_1),Navigate(Failed_Screen));

Reset(TextInput1);

Reset(TextInput2);

Step 5: Handle Navigation

If the credentials are valid, navigate user to your app main screen else navigate user to error scree.

 Login error screen :

Login successfully:

Step 9: Publish and Share

Once testing is complete, publish your app.
