Hi This error happens mainly when the value we set for dropdown is not in the list. Try below code. if (drphh1.Items.FindByValue(rdr[5].ToString()) != null ) { drphh1.Text = rdr[5].ToString(); } Please go through below thread - https://stackoverflow.com/questions/19770207/dropdownlist-has-a-selectedvalue-which-is-invalid-because-it-does-not-exist-in-t
