problem with grid.splitAt() function

hi

iam using grid.splitAt(1) function in my code.I used this function after intialising the grid.problem is whenever i use the function grid.splitAt() ,mygrid.attachEvent(“onXLS”,function()) is not working.

Event is not related to split mode, and must not be affected by it.
