Question

我有一个绑定到SqlDataSource的GridView。我遇到了执行UpdateCommand的问题，它似乎正在执行两次。当我逐步执行gvChecklist_RowUpdating事件中的代码时，我看到一切正常运行并且执行了存储过程。我已经验证了存储过程正常工作，因为db表中有一条新记录。当此事件退出时，我收到以下错误：

过程或函数usp_TestLogInsert有太多参数指定。

我看到在RowUpdating事件之后正在调用数据源上的Updating事件。我试图取消此事件以防止多次更新尝试，但没有任何反应，GridView保持编辑模式。

ASP代码

protected void gvChecklist_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    SQLConnections sql = new SQLConnections();
    SqlDataSource dsChecklist = (SqlDataSource)LoginView1.FindControl("dsChecklist");
    var dd = (DropDownList)gvChecklist.Rows[e.RowIndex].FindControl("ddStatus");
    var status = dd.SelectedValue;
    var testID = sql.SQLSelectSingle(String.Format("SELECT ID FROM Automation.manual.Tests WHERE Task = '{0}'", (String)e.OldValues["Task"]), "pwautosql01");
    string user = Page.User.Identity.Name;
    string notes = (String)e.NewValues["Notes"];
    string jira = (String)e.NewValues["JiraTicket"];
    var dbID = e.NewValues["ID"];
    string build = "TODO";

    if (dbID == null) //Record does not exist in TestLog, INSERT a new one
    {
        dsChecklist.UpdateCommand = "[Automation].[manual].[usp_TestLogInsert]";
        dsChecklist.UpdateCommandType = SqlDataSourceCommandType.StoredProcedure;

        dsChecklist.UpdateParameters["Status"].DefaultValue = status;
        dsChecklist.UpdateParameters["TestID"].DefaultValue = testID;
        dsChecklist.UpdateParameters["TestedBy"].DefaultValue = user;
        dsChecklist.UpdateParameters["Notes"].DefaultValue = notes;
        dsChecklist.UpdateParameters["JiraTicket"].DefaultValue = jira;
        dsChecklist.UpdateParameters["Build"].DefaultValue = build;

        gvChecklist.DataBind();
    }
    //else //Record already exists in TestLog. UPDATE
    //{
    //TODO
    //}
}

编辑：我使用SQL事件探查器查看存储过程中发送的参数。即使发生INSERT并创建了新记录，也会发送一个名为ID的额外参数。我从来没有明确地发送过这个参数，但它似乎是因为我在GridView中有一个名为ID的BoundField而创建的。要构建原始问题，是否有办法使UpdateCommand忽略此BoundField，因此它不会自动将其用作参数？

Answer 1

使用SQL事件探查器后，我看到BoundField ID被隐式添加为UpdateCommand参数。将此字段更改为TemplateItem可以解决此问题。

                       <asp:TemplateField>
                        <ItemTemplate>
                            <asp:TextBox ID="tbId" Text='<%#Eval("ID") %>' ReadOnly="true" runat="server"></asp:TextBox>
                        </ItemTemplate>
                       </asp:TemplateField>

SqlDataSource UpdateCommand被称为两次
