Что я уже пробовал:

protected void btnsave_Click(object sender, EventArgs e)
 {
     try
     {
         using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
         using (SqlCommand cmm = new SqlCommand())
         {
             cmm.Connection = cnn;
             cmm.CommandType = CommandType.Text;
             if (btnsave.Text == "Save")
             {
                 cmm.CommandText = "INSERT INTO register_user([name],[email],[email_pass],[panel_pass],[dept])" + "VALUES(@name,@email,@email_pass,@panel_pass,@dept)";

                 cmm.Parameters.AddWithValue("@name", txtname.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@email", txtemail.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@email_pass", txtemailpass.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@panel_pass", txtpass.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@dept", ddldept.Text.Trim().ToString());

             }

             else
             {
                 cmm.CommandText = "UPDATE [register_user] SET name=@name,email=@email,email_pass=@email_pass,panel_pass=@panel_pass,dept=@dept where id=" + ViewState["id"];

                 cmm.Parameters.AddWithValue("@name", txtname.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@email", txtemail.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@email_pass", txtemailpass.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@panel_pass", txtpass.Text.Trim().ToString());
                 cmm.Parameters.AddWithValue("@dept", ddldept.Text.Trim().ToString());



                 }
                     cmm.Connection.Open();
                     cmm.ExecuteNonQuery();
                     cmm.Connection.Close();

                     ScriptManager.RegisterStartupScript(this, GetType(), "Success", "alert('Information Save Successfully.');", true);
                 gvbind();
                 clear();
             }
         }
         catch (Exception ex)
         {
             Response.Redirect(ex.Message);
         }

 }
