supriya931 25-Feb-13 4:33am

You mean, You want to display Checkbox with value 1, 2, 3, 4 in all rows of Grid? or the checkbox will be changed by any condition?
supriya931 25-Feb-13 5:02am    
no see the format is like

qid qtxt op1 op2 op3 op4
1 hghg hh then checkbox hg then checkbox gjg then checkbox hhg then checkbox
willington.d 25-Feb-13 5:11am    
Ok.. I understood now. So you have to dispaly Checkboxes in a grid based on the answers.
for example:
qid qtxt op1 op2 op3 op4
1 hghg hh then checkbox hg then checkbox gjg then checkbox hhg then checkbox
2 ere ChkBox chkbox
3 2325 chkbox chkbox chkbox

So u want like the above correct?
