Grid with Subgrid problem in subgrid heading

we are using grid with sub_row option. in the sub_row we are dynamically generating one more grid. while generating dynamic grid we want to supress the heading for the grid. but if i remove the heading the sub-grid won’t generate. how do i hide the heading the sub-grid. here my sample xml string am using in the sub-row column.

example output:

Response.ContentType = “text/xml”
response.write ("<?xml version='1.0' encoding='UTF-8'?>")

response.write (“1500A Time to Kill1500A Time to Kill”)

You can hide grid header with setNoHeader() method:
mygrid.setNoHeader(true);
But in such case header cannot be shown again.
