Filter a Gallery using buttons

[Chris_Aguirre]

Hi i have this gallery in my app browsegallery1 with this on Items = SortByColumns(Search([@POOL], TextSearchBox1.Text, "MATERIAL","NOMENCLATURA","NUMERO"), "MATERIAL", If(SortDescending1, Descending, Ascending))

In other Screen i have two buttons, i want to filter the gallery with the column "MATERIAL", i have two options there "CEMENT" and "pouzzolane"

i have this code in the buttons but it doesn't do anything

 UpdateContext({ds: Filter(POOL,MATERIAL="PUZO")});Navigate(BrowseGallery1,ScreenTransition.None)

thanks in advance

UpdateContext() only works on the same screen.  You need to use a global variable if your variable is on another screen: Set(ds, Filter(POOL,MATERIAL="PUZO")) should do the trick.

Like Drrickryp said, updatecontext is a local variable compared to a global from Set(). If you are working with both, be sure to label the variables as such. I had a big issue with accidentally using a local variable that had the same name as a global variable. Or the other way around, I completely overhauled the code instead of trying to find where the wires got crossed. For globals I use either varTest or glblTest and for locals I use lclTest or locTest. Whatever you use, be consistent and do not change all willy nilly or it just creates more headaches.
