No Item to Display screen issue

Posted on 3 Mar 2023 10:31:25 by 39

Hi 

 

I have two forms and a gallery function to call data from a list. I am unable to use the gallery on its own as the information that I need displaying contains a lot of text data.

 

As such I have a opened a new form to pull data from a second share point list. All the functions work as I expect it to behave, but the 'No Item to Display' message appears till I press the arrow button.

 

Is there away to hide this? If not, I have another solution in my head, but I am unable to implement it as I am familiar with PowerApps coding. 

 

Second Solution ( Without using a Gallery function): Create a second form as mentioned in the picture.  Connect data source from the Share Point List 2.  Use a data card (Formula to obtain data from previous screen DataCardValue8. Selected. Value ) to carryout the function same as the Gallery and display it. 

 

Use coding to pull data from SharePoint List 2 based upon the data card's value. 

 

I have tried to elaborate as much as possible on the picture that I have attached.

    Yes, So keep it the same so that it will populate, but just add in Navigate(ScreenName)

     

    Screen name being whatever you've called the screen with the form, don't forget to add a back button to the second screen which can take you back to the main gallery screen

    does it need to state:

    Select (Parent); Navigate(Edit Screen3)

    Well I think it's meant to do that... the Form can't populate until you tell it what to populate with..?

    Only thing i can suggest is to have the form on a different screen and add a 'Navigate()' function on to the arrow

    I still have the same issue... It requires me to press the arrow key to populate the data...

    Re: No Item to Display screen issue

    Is the form set to edit or new?
