How to set columns width to grid width

Hi,

I have grid (AW.Grid.Extended) with 2 columns, that grid should fix into a frame, so I set grid width to 100%, and disabled scroll bars. And I am setting width=50% to each column (column-0 & column-1), it is not working. How to adjust columns in a grid? And if I resize the window/frame the columns width should change according to grid. That is nothing but changing width of grid and column dynamically.
And there is a problem with setting height to 100%, is there any other way to set height.


Plz anybody help me.
