name of column's data source were changed when create search gallery screen
I'd like to create search gallery screen. When 'items" used datasource name, everything was fine.
but when I tried to change items to become search(datasource name, textboxsearchname.text,"column name1","column name 2") I couldn't fine the columns's name. the changes to become names that I didn't know where came from
Please advise, what should I do si I can create multi column search.
