CheckboxList control

Question

Hi all, I have a checkboxlist control on a webpage and I populate it based on a list of present on the database. Each user has a preference which is stored in the database. When the user want to edit these set of preferences I have to display the intial chosen ones. Link is what I found, my code is for(int i = 0; i < myDS.Tables["TrailInterest"].Rows.Count; i++) { if(Int32.Parse(myDS.Tables["TrailInterest"].Rows[i]["TrailID"].ToString()) == TrailId) { strTemp = myDS.Tables["TrailInterest"].Rows[i]["InterestType"].ToString().Trim(); ListItem li = cblInterests.Items.FindByText(myDS.Tables["TrailInterest"].Rows[i]["InterestType"].ToString().Trim()); if(li != null) { li.Selected = true; } } } But the checkboxes aren't checked. What am I doing wrong? Thanks Pria
