Scrollbar scenario I cannot make with a grid

Hello all!

I want to build a grid with only the vertical scrollbar, but I want it to be disabled if there aren't enough rows and enabled otherwise.

I have tried this

obj.setScrollBars('vertical'); 
    obj.onScrollBarsChanging  = function(){return 1};

but when the scrollbar must be disabled appears only a white strip, when the scrollbar is needed it appears just ok.

I've seen also that if I put "both" instead of vertical, I can obtain a vertical scrollbar that is disabled and enabled, but I also have the horizontal scrollbar which I don't want. I've tried to hide it but with no result.

Perhaps you can give me a hint. Thank you!

Strange. When I try this - I am always getting the vertical toolbar, enabled or disabled depending on the number of rows (tried IE7, FF2, FF3, AW 2.5.2).

var obj = new AW.UI.Grid;
obj.setId("myGrid");
obj.setCellData(function(col, row){return col + "." + row});
obj.setHeaderText("header");

obj.setColumnCount(3);
obj.setRowCount(10);

obj.setScrollBars('vertical');
obj.onScrollBarsChanging  = function(){return 1};

document.write(obj);

Hi Alex!

finally I found what was wrong, it was just a stylesheet issue. We are working with a modified stylesheet and this is what was making appear the white strip instead of the bar.

Thank you very much and keep going on!
