Как я могу найти индекс, который был вне диапазона, мой индекс все равны

---

Я уже подсчитал столбец, и индекс все еще получил ошибку, что мой индекс был вне диапазона, может кто-нибудь мне помочь, пожалуйста..

var query = "SELECT [tblemployee].[id] ,[tblemployee].[EMP ID], [tblemployee].[FIRST NAME], [tblemployee].[LAST NAME], [tblemployee].[MIDDLE NAME], [tblemployee].[EMAIL], [tblemployee].[EMAIL PASSWORD], [tblemployee].[ADDRESS], [tblemployee].[CONTACT], [tblemployee].[CIVIL STATUS], [tblemployee].[BIRTH DATE], [tblemployee].[BIRTH PLACE], [tblemployee].[EMERGENCY CONTACT], [tblemployee].[USERNAME], [tblemployee].[PASSWORD], [tblempworkinfo].[d_hired], [tblempworkinfo].[d_rate], [tblempworkinfo].DEPARTMENT, [tblempworkinfo].position, [tblempworkinfo].w_status, [tblempworkinfo].w_type FROM[tblemployee] INNER JOIN tblempworkinfo ON tblemployee.[EMP ID]=tblempworkinfo.[EMP ID]";
				_sqlhelper.ViewDatagrid(dgEmployeeList, query);
				switch(msgBoxResult)
				{
					case MessageBoxResult.Yes:
						var row = (DataRowView)dgEmployeeList.SelectedItems[0];
						{
							
							var EditEmployee = new frmAddEmployee
							{
								txtID = { Text = (row["id"]).ToString(), Visibility = Visibility.Hidden },
								txtEmpID = { Text = (row["EMP ID"]).ToString() },
								txtFName = { Text = (row["FIRST NAME"]).ToString() },
								txtLastName = { Text = (row["LAST NAME"]).ToString() },
								txtMname = { Text = (row["MIDDLE NAME"]).ToString() },
								txtEmail = { Text = (row["EMAIL"]).ToString() },
								txtEmailPassword = { Text = row["EMAIL PASSWORD"].ToString() },
								txtAddress = { Text = (row["ADDRESS"]).ToString() },
								txtContacNo = { Text = row["CONTACT"].ToString() },
								cmbStatus = { Text = row["CIVIL STATUS"].ToString() },
								dtpdbirth = { Text = row["BIRTH DATE"].ToString() },
								txtPlaceOfBirth = { Text = row["BIRTH PLACE"].ToString() },
								txtEmergencyNo = { Text = row["EMERGENCY CONTACT"].ToString() },
								txtPassword = { Text = row["password"].ToString() },
								txtUsername = { Text = row["username"].ToString() },
								txtRate = { Text = row["d_rate"].ToString() },
								cmbEmployeeStatus = { Text = row["w_status"].ToString() },
								cmbPosition = { Text = row["position"].ToString() },
								cmbDepartment = { Text = row["DEPARTMENT"].ToString() },
								cmbWorkStatus = { Text = row["w_type"].ToString() },
								dtpdatehired = { Text = row["d_hired"].ToString() },
								btnSave = {Visibility = Visibility.Hidden },
								btnUpdate = { Visibility = Visibility.Visible },
								btnDelete = { Visibility = Visibility.Visible },
								
								Title = "Manage Employee Information",
								//btnSave = { IsEnabled = false },
								//btnDelete = { IsEnabled = false }	
							};

Что я уже пробовал:

Я уже считаю столбец и индекс все еще
