Solution 1

I think here ur checking for the indexof the checklistitem(instead of verifying the value which is stored in a table)

just compare the value of the checklist and the value in the datatable

You generate a set of integer indexes in the variable 'i in the outer for loop, but you never use the variable 'i in the loop.

"if (chk.Text.IndexOf(dt.Rows[0][0].ToString()) > 0)"

IndexOf returns an integer ... then you convert that integer to a string, and then you compare it to an integer ... that should give you a compile error right there.
