I have created a scrollable gallery, and am using headers (labels) outside the gallery to create an excel-like view for the user, using this idea: https://michalsacewicz.com/power-apps-horizontal-scroll-in-a-vertical-gallery-with-freeze-panes-effect/
It all works fine, when I scroll the gallery, the headers move with it etc. All good. However, I am now adding filtering to the gallery - so there's a search box where they can search the title field and some dropdowns. The search/filtering itself is working as expected. but the first time (and only the first time) that a filter is applied (whether by search text box or dropdown selection), the X property of the arrow at the end of the gallery (to select parent) evaluates to blank when used in a formula, even though it is still in the right place on the page.
See screenshot: - on the right, the position x is showing 1316 (and it's in the right place on the screen), but when used in a formula, it shows blank. The formula used in the label is: "EditIcon.X: '" & EditIcon_RTRGallery.X & "'"
The effect of this is that the headers above these fields 'disappear' because their location is not 'less than' blank.
Now, if I change the search field - either by removing a character, changing it completely, or adding a letter etc, then it suddenly works as expected, and in a formula EditIcon_RTRGallery.X will give a number instead of a blank. But I can't work out why it's doing it on the first time. I don't want users to have to mess around with the search box to get it to work. I've included a second screenshot that shows when I added more words, the headers reappear and the label at the bottom shows the actual X value instead of blank. If I then change it back to just the first word, the headers stay and everything is normal.
Any ideas?!
