Disabling Multiple uicontrol Buttons using array

Ran in:
I was wondering if there was anyway of disabling all the buttons in the array without a for loop? I can individually disable the buttons by referencing their positions within the array using the last statement in the code.
rez = get(groot,'ScreenSize');
buttonScaling = rez(3)/rez(4); %Dynamically scales size of buttons with resolution
H = .085*buttonScaling; %Height of button
W = .045; %Width of buttons
B2T = .727-3*H; %Distancing from Bottom 2 Top
L2R = .375; %Distancing from Left 2 Right
gap = .001; %Distance between buttons
number = 0; %Starting number
MAIN = figure('Position',rez,'Color','black','MenuBar','none','NumberTitle','off');
%Loop to automatically place down buttons and order them from 0 to 36
for across = 1:3 %//How many columns
B2T = .727-3*H; %//Resets height for each new column
for up = 1:3 %//How many rows
number = number + 1;
%//Checks if number is a member of the reds or blacks
if ismember(number, 1:7)
buttonColour = 'r';
elseif ismember(number, 7:9)
buttonColour = [0 0 0];
end
%An array called grid is created for debugging purposes, easy
%indexing for each button
grid{up,across} = uicontrol('style','pushbutton','units','normalized','position',[L2R, B2T, W, H],...
'String', number,'FontWeight','bold','FontSize',32,'Backgroundcolor',buttonColour,'ForegroundColor','w',...
'UserData', number, 'Callback', @bettingNumber);
B2T = B2T + (H + gap*buttonScaling); %//Shifts the next button down by the scaled gap
end
L2R = L2R+W+gap; %//Shifts the next column of numbers by the width of each button and the gap in between
end
grid{1,3}.Enable = 'Off';

Yes. For instance to disable all uicontrols in column 3 of grid:
set([grid{:,3}],'Enable','off')
By the way, you can store uicontrols in an array (cell array not required):
grid = zeros(3); % numeric array
for i = 1:3
for j = 1:3
grid(i,j) = uicontrol(...)
end
end
which would make the syntax a little simpler:
set(grid(:,3),'Enable','off')
