CheckBoxList2.Items[j].Selected = true;
}
//else CheckBoxList2.Items[j].Selected = false;
yes_or_no = y["ISGoal3"].ToString();
yes_or_no = yes_or_no.Trim();
if (yes_or_no == "Yes")
{
CheckBoxList3.Items[j].Selected = true;
}
//else CheckBoxList3.Items[j].Selected = false;
yes_or_no = y["ISGoal4"].ToString();
yes_or_no = yes_or_no.Trim();
if (yes_or_no == "Yes")
{
CheckBoxList4.Items[j].Selected = true;
}
//else CheckBoxList4.Items[j].Selected = false;
yes_or_no = y["ISGoal5"].ToString();
yes_or_no = yes_or_no.Trim();
if (yes_or_no == "Yes")
{
CheckBoxList5.Items[j].Selected = true;
}
//else CheckBoxList5.Items[j].Selected = false;
}
}
y.Close();
}
employeeid[] contains id of 6 employees.no_of_listitems is 6 which is the list of thses 6 employee ids.

Answer 1

Create a list with your CheckBoxList in it. Then, replace the code with something like this:
for(int z = 1; z <= checkboxLists.Count; z++)
{
checkboxLists[z].Items[j].Selected = y["ISGoal" + z].ToString().Trim() == "yes";
}
Keep in mind though that this code is not type-safe. Normally, you'd want to avoid using string in your code and y["ISGoal"+z] might be null. If it is, the application will crash. This mean you want to make checks to make sure it's ok. Trying to make a ToString() or Trim() on null will make a NullPointerException. You might also want to change "yes" by bit in your database. It would be much more safe to work with. What if someone writes "true" instead of yes?
I hope it helps out. If you have any question, don't hesitate.
