Hi,

I am planning to develop an PowerApps application, wanted to know few clarifications on below points:

1) Which is better one for Customizing application and CDS is source? - Canvas App or Model Driven App

2) How to define below category and subcategory options and styles in Dropdown box in PowerApps

3) Where should I keep the Radio Button options data? in CDS(having options of "Choice" datatype - Enabled/Disabled) or in PowerApps?

4) is it good idea to keep only CategoryID and SubCategoryid in Main entity of CDS and reference as primarykey/foreignkeys in Category and Subcategory entities?

Thanks

Durga

Hi Durga,

1. A canvas app will be more customisable than a model driven app.

2. With drop-down controls in a canvas app, you can use the 'depends on' setting to define dependencies. A good place to start is the documentation on dependent dropdown lists here...

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/dependent-drop-down-lists

3. It is fine to store the 'enabled/disabled' radio options in a choice field. A benefit of this is that it works euqally well with both canvas and model driven apps. If the choices you want to offer are likely to change or if you want to disable certain choices depending on some condition, I would recommend that you store the choices in a separate entity.

4. This depends on your data model. If each record in your main entity is associated with a subcategory only, you would only need to create a lookup to the subcategory entity from your main entity. If you describe the data that you want to store in more detail, we can comment further on this point.
