The Switch Control issue : Power Automate

 Today I ran into a unique scenario. I had to trigger emails on dropdown change of a field in my Power App. 


Power Automate was the obvious choice but since i had 4-5 options in choice field i decided to use Switch control rather than the condition control.


Switch control is an interesting control, it not only makes your flow short, but also more efficient.


But there is a bug in the Power automate Switch control.


Lets get into it. All you need to do is replace your column Name choice with the below Coalesce Function.

coalesce(triggerBody()?['Stage']?['Value'],'Unknown')





This will help you remove the bug in Switch control which otherwise will throw an exception like below.


The execution of template action ‘Switch’ failed: The result of the evaluation of ‘scope’ action expression ‘@triggerBody()?[‘Choice’]?[‘Value’]’ is not valid. It is of type ‘Null’ but is expected to be a value of type ‘String, Integer’

 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.
