autowidth set the grid initially to the width of the parent container. After that you should apply some coding to set the grid width when the container changes its width. Also the demo page of 3.5 uses this mechanism in order to do that. Go into the demo page and tru to resize the splitter - see how grid is resized according to the new width.

To be more specific, I want to put the grid into a portlet, which could be of any size. I would like to allow the grid to fit into the portlet automatically no matter if the portlet is small or maximized.

If there's a way to set width to 90%, that will be great!

Thanks!

I want to have a table that occupies the whole width of the screen. For this I use autowidth to true.

The problem is that I want to show / hide columns and that the table continues occupying the whole screen.

How can I do it?

Thansk!!!
