ActiveWidgets • dynamic height on a data grid not working for 2.5.1

Under version 2.0.2 for the datagrid I was setting the grid height
using the command

grid.setStyle('height', '80%');

and it work fine.

I loaded up the new 2.5.1 version and now it will only initially display 6 lines. If I set the height to a fix size, there is not problem. Is this not an option anymore with the newer version.

Should be a bug - could you post (or send me) a full page html? I guess this is some kind of problem with nested tables layout.

Alex,

Here is the code that you requested

Alex,

Ignore the variable "colWidth". For got to remove it. It does not do anything.

This is indeed a bug in the grid initialization procedure - the total height value is incorrect. It will be corrected in the next bug-fix release. Please try the following code as a temporary workaround -

docGrid.paint = function(){

    var h = this.getScrollTemplate().element().offsetHeight;

    this.setTimeout(function(){

        this.setContentHeight(h, "total");

        this._virtualController.paint.call(this);

    });

}

Alex,

Thanks, that fixed the problem in IE. I did notice that the grid does not display correctly in firefox when I use a percentage for the hieght. It does display correctly when I put in a actual number. Is this just a IE vs. Firefox thing?

You have to specify the DIV height in Firefox. The DIV element does not have width and height attributes so you have to specify width/height using style -

<DIV id="myDiv" style="width:100%;height:100%"></DIV>

Fixed in AW 2.5.2.
