Form UI and performance

(0) ShareShare

Posted on by wen90 40

Hi, 

 

I am new to Portals but really excited to use it for external users. I have two questions, 

 

1) Do we have any control over the form UI given its a model driven app? Ie. Can we have radio buttons, split columns for some sections, headings on the side to open up the form questions?

 

2) We had to use Canvas apps to build our applications given the forms are so big. Are there any performance issues with lots of form entities in Portals? Ie. 50 questions containing 3 data inputs - dropdown, yes/no and comments? 

 

Thanks for the help, really appreciate it!

    Hi

     

    Think of the Portals as a normal asp.net website and not as a Modern Apps / Canvas Apps

    You can perform any control customization you want, via regular web dev components (CSS and JavaScript libraries)

     

    About performance, Microsoft is continuously improving performance of Power Apps Portals, but currently is still not the most performance website you can find

    Is your application like a single form or a web form with multiple steps, Microsoft fixed a bunch of performance issues with Web Forms so so recently, so depending on the number of users you have it might or might not be an issue, it's really hard to say

     

    there are no benchmarks available from Microsoft in regards Portals performance at the moment

     

    Web Forms documentation: https://docs.microsoft.com/en-us/powerapps/maker/portals/configure/web-form-properties

    Hi @wen90 ,

    For your first question, could you please share a bit more about your scenario? Do you want to customize the UI within the Model-Driven app form?

     

    If you want to customize the UI within the Model-Driven app form, I afraid that there is no direct way to achieve your needs. If you want to customize controls in Model-Driven app form, I think PowerApps Component Framework could achieve your needs, please check the following article:

    https://docs.microsoft.com/en-us/powerapps/developer/component-framework/overview

     

    If you want to custom Commands or Ribbon in Model-Driven app, please check the following article:

    https://docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/customize-commands-ribbon

     

    For your second question, the answer is Yes. The more Edit forms you added into your canvas app, the more CPU resources, memory, and network bandwidth would be consumed within your canvas app, so the app performance would be decreased.

    More details about the Performance tips for canvas app, please check the following article:

    https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/performance-tips

     

    Best regards,
