Template size of a gallery

(1) ShareShare

Posted on by DerrickH 194
Hi all, 
 
Does anyone have any experience with dynamically sizing the template size of a gallery based on the number of rows in the gallery?
 
I'm trying to size the height of the template size based on the number of rows divided by the height of the actually gallery, can this be done?

    What is the 'Items' property in your gallery? Does it reference one of the gallery's own properties?

    Thanks!  though I'm getting an error on the TemplateSize property. 
     
    Formula:  Self.Height/Self.AllItemsCount
     
    Error:  "This rule creates a circular reference between properties, which is not allowed.  A property cannot reference itself or other properties affected by its value."

    You can set the TemplateSize property of the gallery to a formula like the one below to do that:
     
    Self.Height / Self.AllItemsCount
     
    This would make the gallery template resize depending on the number of rows:
     
     
    Hope this helps!
