Matt Peterson is back with another insightful tutorial on our YouTube channel. Whether you're a seasoned pro or just diving into the Power Platform world, Matt's got you covered. Today, he's tackling a common challenge faced by model-driven app users: filtering lookup columns. Let's dive into Matt's step-by-step guide on making this process seamless.
The Lookup Conundrum
Ever found yourself scratching your head over lookup columns in model-driven apps? Matt gets it. Picture this: you're creating a travel record, selecting a state, and then bam! You're flooded with cities from every corner of the globe, not just the one you're interested in. Frustrating, right? But fear not, Matt's got a solution.
Step 1: Adding a Parental Connection
1. Identify the Subcategory Field: In Matt's scenario, it's the city lookup dependent on the chosen state. 2. Navigate to Solution: Head to the solution in your model-driven app. 3. Add a Lookup Column: On the city table, add a new column (e.g., State) as a lookup to the state table. 4. Save and Publish Form: Ensure this new column is added to the form and publish the changes.
Step 2: Form Modification Magic
1. Travel to the Travel Table: Head over to the main form in the travel table. 2. Filtering Time: Click on the city lookup field in the form. 3. Filter by Related Rows: Activate this option to filter based on the relationship with the state table. 4. Choose Relationships: Specify the relationship to the current table (travel state to city) and the lookup table (state to city). 5. Save, Publish, and Disable Most Recently Used Items: Make sure to save and publish the form, and for an added touch, disable the recently used items to enhance the filtering experience.
Step 3: Putting It to the Test:
1. Associating Cities with States: Link cities to their respective states in the city table. 2. Refreshing the Model-Driven App: Matt refreshes the app to showcase the changes. 3. Testing the Filter: Matt selects Florida as the travel state, and voila! Only Jacksonville and Orlando, the cities associated with Florida, appear.
Relationship Precision: Ensure your relationships between tables are correctly defined.
Save and Publish: Always save and publish your changes for them to take effect.
Testing Across Different Scenarios: Try different states and cities to guarantee the filter works consistently.
