Using Version 2.5 Beta 2 Code

I am using the version 2.5 beta 2 code
The ext dhtmlxtabbar_wins.js is no longer available in this version and I attached the grid using the example in the provided documentation.
dhxGrid = dhxTabbar.cells(“t1”).attachGrid();

When using the previous version of the code I did use the code you suggested to attach a grid.  Resizing was not an issue then.

Code below:


    html, body {
        width: 100%;
        height: 100%;
        margin: 0px;
        padding: 0px;
        overflow: hidden;

Please check

While dhtmlxcontainer.js is included, you need not any extra js files for a tabbar.
It will support all set of attach command by default.
