How to set dynamic height of Gallery?

Hi Everyone,
I have a flexible gallery with dynamic row height.
Suppose row- 1st height: 200
                       2nd height: 150

 ''               ''    3rd height: 257
so it could be dynamic and if I have only 1 record in gallery then I want to remove extra spaces in gallery.
Screenshot attached:

So I have much more extra space after 1st record, that I want to remove. (Reason behind that: I have multiple galleries on the same screen, so If I will be able to make it dynamic height then that will reduce unnecessary space on screen)

Thanks

Hi @sayyedkohler ,

Height of a gallery would be

CountRows(Self.AllItems) * (Self.TemplateHeight + Self.TemplatePadding) + Self.TemplatePadding 

 

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Hi @sayyedkohler ,

What variations have you tried?

I actually doubt you can do it completely accurately as you do not have constant values to work with.

I tried @WarrenBelz but still space is there.

@sayyedkohler ,

As I mentioned, the code I supplied is for a "Standard" gallery - I do not think there is a formula for a flexible height item that will work as there are no static values able to be referenced on the Template Height (that is why it is called Flexible)

okay @WarrenBelz.
Thanks for the help.

So we can not set dynamic height on Flexible galleries.
Any way at least I have solution for standard gallery now.

Hi @sayyedkohler 

To Address the gallery section there are many ways, Different for every Control, for label just turn on auto height and for seprater set it’s Y property as DescriptionLabel.Y + DescriptionLabel.Height + 10, I also will have to Adjust the Edit and Delete Button Accordingly.

Using (DescriptionLabel.Height / 2) – 10, after that the you will get result.

It Can be Used with Other Controls as well, like for Text Input we can use a Checkbox to trigger size change. i.e. if Current Item Checkbox checked then Text Input Height = 30, else 170.

 

 

May be its useful. Do try this.
