Solution 3

Looks too complicated for what it's supposed to do.
I would try something like this first:

C#

char[] delimiter = { ',' };
string[] k = objP.Salary.Split(delimiter, StringSplitOptions.RemoveEmptyEntries);
            foreach (string m in k)
            {
                foreach(item i in chklstSalary)
                {
                   if (i.Value == m)
                    {
                        chklstSalary.i.Selected = true;
                    }
                }
            }

Solution 4

string lang;

lang = ds.Tables[0].Rows[0]["languages"].ToString();
string[] k = lang.Split(',');
for (int m = 0; m <= k.Length-1 ; m++)
{
for (int i = 0; i <=CheckBoxList1.Items.Count-1; i++)
{
if (CheckBoxList1 .Items[i].Value == k[m])
{
CheckBoxList1 .Items[m].Selected = true;
}
}
}

Try: chklstSalary.Items.Count -1
also, you use i for chklstSalary and cannot mix it with m (when you set the selected). Try this:

C#

if (chklstSalary.Items[i].Value == k[m])
{
   chklstSalary.Items[i].Selected = true;
   break; // no need to loop any further because we already found the matching checkbox
}

Good luck!
