Extend last column in grid.

I create the grid inside div, with div I set up width = 100%. When screen’s resolution is 1024*768, grid display full screen and beautiful. I increase screen’s resolution to 1280*1024, grid display full but columns not display full. In winform, grid have property is ExtendLastColumn, and how about dhtmlxGrid??

Thank you for any help.

When defining width of columns, for last column set it as *

grid.setInitWidths("100,100,100,*");
