Power Apps: Antiquity

Workflows will soon be deprecated, but what is better is that its successor is even more powerful. And what a coincidence its even called as Power Apps.

Being a SharePoint developer is tough, as your client considers anything and everything related to SharePoint as part of SharePoint. So if an app fetches and updates data in SharePoint list, then you got to know that app buddy. And that is precisely the reason i ended up exploring about Power Apps. I know i am a bit late to the party, but hey now most of the things are stable in MS Power sphere, and we will explore it to bits. Literally tear it!!

There are two types of Apps
  1. Canvas
  2. Model Driven Apps

Canvas Apps are UI centric apps and are basically used for the purpose of task or role based applications.
All you need to do is drag and drop the controls. Connect the datasource using the awesome list of 200 plus and counting connectors and voila!  These are non responsive by default, and you have to do lots of work to make them responsive.

Model Driven Apps on the other end are used for complex business logics. They are Data centric and use CDS( Common Data Service) to connect to a data source. Also they are responsive by default and no effort is required to make them responsive.

There is a beautiful article here explaining the differences which i referenced.

You can share your Canvas app as well as Model driven apps but you can also distribute your model driven apps using a solution component. All you need to do is make it into a solution component i.e. a zip file move it across the environment and republish it.

There is more on this neatly at MS site.

App Makers/Creators

Canvas Power App is made in App studio where as Model driven apps are made in App Designer.

The two Admin Centers are as below
  • Power Apps Admin Center: which is basically used to create and manage environments, users and DLP.
  • Power Platform Admin Center: which is used for managing the environments, analytics, support for Power Apps and Power Automate.

Creating Nested Galleries in Power Apps. (Parent-Child Relationship)

Image
 This is another most common scenario where in client has two parent child lists or any two lists having a common SharePoint column. And clients wishes to have a relationship on the PowerApps screen where in when he/she selects a particular lets say Program in our example. All the respective Projects following that Projects are shown. In such a scenario we can leverage nested galleries. So what we do in here is we add two galleries on our Power App screen. For Programs gallery the Left one on the screenshot above, we connect it to the Programs list For Second gallery we will connect it to the Projects list. But this is where the magic happens. Here we use Filter () function. So what we do in here is we set the Program's column value in Project's list equal to the Selected Program of left Gallery. i.e. the gallery connected to my Program's list. A more complex version of the same is where you inset the nested gallery inside your parent gallery. In this too everything remains

How to reset a datepicker control in PowerApps?

Image
 Scenario: Simple reset a date picker control. Issue, you can't use normal Reset() function to reset the datepicker control. Solution: Simple create a variable Set(varResetCD, True) and use this variable to update the reset property of DatePicker control. The below Reset() won't work in case of datepicker control We need to create a variable and use it at the Reset property of the datepicker control. Also, if you still see some text inside your date field there are two other places you need to check in one is the datepicker control advanced properties. In the above screenshot all you need to do is clear InputTextPlaceholder. And then select the control and check the DefaultDate property of the date.  This should be set to Today(), you can also change it to something like below If(varResetCD,Blank(),Today()) What this does is sets the control to blank if the variable you have declared above is true.

The flow for these dropdowns is that a user selects the Division, and a list of Business units containing the selected Division is popped down in your Business Unit dropdown. Now to make it user friendly, we have on change code written on each dropdown. So that if the user decides to change the Division dropdown, the Business Unit dropdown is reset. Please remember in here we are talking in regarding to New Form. On Resetting the above Division combo box, since we have written the Reset function code on Change property of the Division Combo box.   Reset(ddBU);Reset(ddBPI);Reset(ddTeams). The above becomes Up till here everything is hunky dory. This is the classic case of how the Reset() function should behave. But that's not, when you move from new form to Edit form.   The Reset function behaves weirdly. It is able to reset the cascading dropdown values like above. But i
