Show values based on Lookup List Conditions for Lookup Column in Power Apps

Overview:

In this article, we will learn how we can show only specific values as Lookup value based on some conditions in Power Apps.

Real-Life Business Use Case:

We have come across a scenario where we have two SharePoint lists.

Domains List:

Request List:

 - Domain is a Lookup column from Domains List in the Request List.

 - We are implementing a Power Apps Form for Requests List.

 - We only want to show those Domains which are active, so how can we achieve this?

Let’s get started!

Step 1: Open Power Apps Form. By default, all values appear in the Lookup Dropdown.

Below is the code for the Default event which is available for the lookup dropdown.

Step 2: Now, we need to change the code with the following code.

 Filter(  
   RenameColumns(  
     AddColumns(  
       RenameColumns(  
         Choices([@Requests].Domain),  
         "Id",  
         "MID"  
       ),  
       "Status",  
       LookUp(  
         Choices([@Requests].'Domain:Status'),  
         Id = MID  
       ).Value  
     ),  
     "MID",  
     "Id"  
   ),  
   Status = "Active"  
 )  

Understanding the code:

 - By default, Lookup has two columns, ID and Value. With the above formula, we added one additional column –“Status” by using AddColumns() function.

 - To achieve this, we need to use the "RenameColumns" function to make the exact final structure that the lookup value expects.

 

- Now, let’s test the result. We can see only Active records in the dropdown.

 

- Now, let’s fill the form and save the value. 

 - The values are stored successfully in the SharePoint list.

Conclusion:

This is how we can apply a lookup list condition to show only active requests in the Lookup column. Hope this is clear now! Stay connected for amazing Power Apps Articles! Happy Power Apping!
