Gridview沒有更新

Question

我有一個網格與網格視圖。我有每行旁邊的更新按鈕。但是當我按下按鈕並編輯字段並按下UPDATE。它不會改變任何東西。下面的代碼：

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"

這裏是它我詹姆斯的幫助下截獲查詢：

updateQuery "UPDATE [Main_LOM_Form] SET [occurrence_date] = @occurrence_date, [report_date] = @report_date, [report_by] = @report_by, [identified_by] = @identified_by, [section_c_issue_error_identified_by] = @section_c_issue_error_identified_by, [section_c_comments] = @section_c_comments, [section_d_investigation] = @section_d_investigation, [section_e_corrective_action] = @section_e_corrective_action, [section_f_comments] = @section_f_comments, [pre_practice_code] = @pre_practice_code, [pre_contact] = @pre_contact, [windows_user] = @windows_user, [computer_name] = @computer_name, [time_stamp] = @time_stamp WHERE [lom_number] = @original_lom_number AND (([occurrence_date] = @original_occurrence_date) OR ([occurrence_date] IS NULL AND @original_occurrence_date IS NULL)) AND (([report_date] = @original_report_date) OR ([report_date] IS NULL AND @original_report_date IS NULL)) AND (([report_by] = @original_report_by) OR ([report_by] IS NULL AND @original_report_by IS NULL)) AND (([identified_by] = @original_identified_by) OR ([identified_by] IS NULL AND @original_identified_by IS NULL)) AND (([section_c_issue_error_identified_by] = @original_section_c_issue_error_identified_by) OR ([section_c_issue_error_identified_by] IS NULL AND @original_section_c_issue_error_identified_by IS NULL)) AND (([section_c_comments] = @original_section_c_comments) OR ([section_c_comments] IS NULL AND @original_section_c_comments IS NULL)) AND (([section_d_investigation] = @original_section_d_investigation) OR ([section_d_investigation] IS NULL AND @original_section_d_investigation IS NULL)) AND (([section_e_corrective_action] = @original_section_e_corrective_action) OR ([section_e_corrective_action] IS NULL AND @original_section_e_corrective_action IS NULL)) AND (([section_f_comments] = @original_section_f_comments) OR ([section_f_comments] IS NULL AND @original_section_f_comments IS NULL)) AND (([pre_practice_code] = @original_pre_practice_code) OR ([pre_practice_code] IS NULL AND @original_pre_practice_code IS NULL)) AND (([pre_contact] = @original_pre_contact) OR ([pre_contact] IS NULL AND @original_pre_contact IS NULL)) AND [windows_user] = @original_windows_user AND [computer_name] = @original_computer_name AND [time_stamp] = @original_time_stamp" string 

我到底做錯了什麼？

Answer 1

我建議添加一個OnUpdating事件處理程序，以便在查詢執行前查看CommandText。這應該可以幫助您確定查詢是否存在問題。

在標記：

<asp:SqlDataSource ID="SqlDataSource1" runat="server" OnUpdating="SqlDataSource1_Updating" ... > 

在後臺代碼：

protected void SqlDataSource1_Updating(object sender, SqlDataSourceCommandEventArgs e) 
{  
    string updateQuery = e.Command.CommandText; 

    //inspect the update query 
}
