Expanding Gallery

I have working on creating a form with multiple galleries.

I need to incorporate the ability for each gallery to expand when a new item is added that goes beyond
the current boundary.

In the example the top gallery has four items, but the fourth one is partially hidden. Is it possible to make
the height of the gallery dynamic to the number of items within them?

@ANB, thank you for your reply.

The video provided is an excellent tutorial on 'TempleSize' height.

I need to know if the height of the 'Gallery' itself can be set dynamically.

In my scenario the user may have one or many items to enter into the Gallert. Unfortunately, as constructed, the Gallery only allow for the first three to be seen.

The rest are only visible when using the scroll bar. This configuration all limits what us displayed when the screen to transformed into PDF and printed.

I am trying to figure out if there is a way to expand thre main gallery so that it shows all items all the time, so that the PDF print will also print all the items in the Gallery.

Hi,

You can have dynamic height using below code:

CountRows(DataSource)*Self.TemplateHeight

I figured it out using the following in the Height of the Gallery -

With(

{

varCountRows: CountRows(

colStockMaterialsItems)

},

varCountRows * Self.TemplateHeight + varCountRows * Self.TemplatePadding

)

The rectangle and Labels below the Gallery have the following, to keep up. Such formulas are also required for anything under the Gallery (with care to make sure the formula height, x and/or y apply to the correct item above).

WO_Component_Gallery_3.Height + WO_Component_Gallery_3.Y
