I am opening highslide on onRowSelect function which works fine.The highslide i have has another grid with “coro” as one of the col types.The combo box in the highslide is not opening(or expanding) when i click on that particular column.This problem does not exist in IE 6.0 but occurs in IE 7.0.
Most probably issue caused by used z-indexes.
You can try to increase z-index of combo , which defined in dhtmlxgrid.css
border-color:black silver silver black;
Thanks a lot! its working fine
