It seems impossible…
If I edit the grid and remove the Advanced Search button from the top toolbar (where by default is located), when I run the grid I get two (?!) Advanced Search buttons: one on the top toolbar and one on the bottom toolbar (where it was never activated). Both of them are aligned at the right side of the grid.
If I remove all fields from Advanced Search, generating the grid returns an error: “Search fields undefined”.
Also, the Advanced Search button is not listed as one of the buttons the sc_btn_display macro can turn on\off.
So, how can I remove Advanced Search button from a grid?
