下面的更新事件

Update event below

protected void grdEmployees_RowUpdating(object sender, GridViewUpdateEventArgs e)
       {
           systemBusinessLayer = new BusinessLayer();

               TextBox txtAddress = (TextBox)grdEmployees.Rows[e.RowIndex].FindControl("txtAddress");
               TextBox txtPhonenumber = (TextBox)grdEmployees.Rows[e.RowIndex].FindControl("txtPhonenumber");
               TextBox txtCellnumber = (TextBox)grdEmployees.Rows[e.RowIndex].FindControl("txtCellnumber");
               TextBox txtEmail = (TextBox)grdEmployees.Rows[e.RowIndex].FindControl("txtEmail");

               int empRecNumber = Convert.ToInt32(grdEmployees.DataKeys[e.RowIndex]["EmpRecNumber"].ToString());



               systemBusinessLayer.upDateEmployeeDetails(txtAddress.Text, txtPhonenumber.Text, txtCellnumber.Text, txtEmail.Text, empRecNumber);
               grdEmployees.EditIndex = -1;
               if (ddlSearch.SelectedValue == ".:Choose Employees:." || ddlSearch.SelectedValue == "Active Employees")
               {

               grdLoadEmployees();
               }
           else if (ddlSearch.SelectedValue == "Deactivated Employees")
               {
