Vertical scrollbar problem on resizing grid

Hi,

When I resize the grid such that the number of visible rows reduce, the vertical scrollbar doesn't appear.
In the example code below, initially I have 7 columns.
I have set a timeout which will resize the grid to half its height in 5 seconds.
In FireFox, Opera and Safari, there is no vertical scrollbar after resizing.
It works as expected in IE7.
Any ideas ?

var obj = new AW.Grid.Extended;
obj.setCellText(function(i, j){return j + "." + i});
obj.setHeaderText("header");

obj.setFixedLeft(0);

obj.setColumnCount(10);
obj.setRowCount(7);
obj.setSize(400, 200);

document.write(obj);

window.setTimeout(function(){obj.setSize(400, 100);}, 5000);
</script>

Just need a final rendering scroll adjustments ,
try :

window.setTimeout(function(){obj.setSize(400, 100);
obj.raiseEvent("adjustScrollHeight");
//obj.raiseEvent("adjustScrollWidth"); 
obj.raiseEvent("adjustScrollBars"); 
}, 5000);

Hi Carlos,

No, that doesn't work.
The vertical scrollbars are still missing.
By the way, the activewidgets version I'm using is 2.5.1

Thanks Ankur,
You'r more than right! ( sorry my bad, I only test that under IE6 ).

Found that adding obj.setScrollBars('both'); fix current test, but it's not an "exact" workaround cause need a proper calculation to know if , after a size change, the vertical ( or horizontal) scrollbar need to be painted.

It would need a complete width+height - ScrollTemplate recalc+setting ( unless if,as always, Alex have found the "short" fixfor the case) :)

Ankur,
This post is related ( and Alex already did a short-temporary-workaround :o ), and seems to solve it ( tested on FF 2.0.011 ) will be corrected in the next bug-fix release.

Hi,

Oops, posted too soon :)
I had obj.setScrollBars('both') set at multiple places and it was working due to that.
The solution at http://www.activewidgets.com/javascript.forum.21650.4/dynamic-height-on-a-data.html doesn't seem to work for this case.
Carlos, are you sure it was working for you (I used FF 2.0.0.12, but I don't think that should make much of a difference) ?

In any case, obj.setScrollBars('both') seems to work in this case.
Maybe Alex will fix this issue in the next release.
Thanks Carlos.

Ankur, This is the testing code I am using:

obj.paint = function(){ 
    var h = this.getScrollTemplate().element().offsetHeight; 
    this.setTimeout(function(){ 
        this.setContentHeight(h, "total"); 
        this._virtualController.paint.call(this); 
    }); 
} 
document.write(obj);
window.setTimeout(function(){obj.setSize(400, 100);obj.paint() }, 5000);

Hi Carlos,

I missed out the obj.paint() call in setTimeout and so it was obviously not working.
Its working fine now.
Thank you very much for all your help.

Thanks,
Ankur
