Using SharePoint list to dynamically navigate screens

[JimboSey]

Hi, 

I have a gallery in my App with the datasource a SharePoint list, I have a 'Navigate Screen' column in my SharePoint list (Single line of text), I have added a button in my gallery, and on the on select I have put the following code 

Navigate(ThisItem.'Navigate Screen')

My SharePoint list column has the name of the screens listed in the 'Navigate Screen' column but I am getting the error 'The first item of Navigate should be a control or screen'.

Where am I going wrong, and what would be the solution if any please?

Thanks

Because the value of the screen coming in from the list is a string - the Navigate() function needs a screen to navigate to (not a string). Notice when you type the name of a screen into a formula bar, it turns a color:

That's what it needs.

How many screens are there? You can consider something like this for your button's OnSelect(),

Switch(

ThisItem.'Navigate Screen',

"Screen Name From Your List",

ScreenNameFromApp,

"Screen 2 Name From Your List",

Screen2NameFromApp

)

You can quickly see how this becomes a problem when you have a million possible values to switch on, and there could likely be a better way to do this.

Hi, thanks for your reply.....

I tried the code as suggested, here is what I included on the button within the Gallery;

Switch(

ThisItem.'Navigate Screen',

"Consultation Screen",

'Consultation Screen',

"Commission Full Form Screen",

'Commission Full Form Screen'

)

However when I select either of the Gallery button it does nothing. 

Any ideas?

Sorry I didn't completely spell out my idea - this is what I meant:

Navigate(
Switch(

ThisItem.'Navigate Screen',

"Consultation Screen",

'Consultation Screen',

"Commission Full Form Screen",

'Commission Full Form Screen'

)
)
