Number of lines in a gallery depends on a variable

Posted on by Community Power Pla... Microsoft Employee

Dear friends,

 

I'm fighting with a gallery.

 

On my forms i got a Slider which its value is between 0 and 24 both includes. Then i have a gallery where i want to have the same number of row as my slider value.

 

My slider value is stocked in a var "dataValue" and my gallery items function is  : "FirstN(CustomGallerySample;dataValue)" 

 

On this photo you can see that there is 3 row because the value of the slider is 3

But on this one, you can see that my gallery is composed of only 4 rows and that i can have more. In gallery option, scroll bar is activated so i don't know what can I do.

    Hi @Anonymous 

     

    Please update the OnChange property of your slider to:
     
    ClearCollect(GalleryRowCount,FirstN([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24],Slider1.Value))
     
    Now in the Gallery, please modify the Items property to GalleryRowCount. 
     
    Hope this Helps!
