ListView取消editItem

Question

我无法使用ASP和C＃返回列表视图并取消项目编辑。

我已经和this有了相同的答案  但我仍然收到Cancel can only be called from the currently-edited record or an insert item.

的错误消息

这是有问题的代码 - 任何关于导致这种情况的指针都非常有用：

我还有一个布局，选定的模板和插入，它们都是相同的。

<asp:ListView ID="ListView1" runat="server" DataSourceID="sqlDatasource1"
                    EnableViewState="true" DataKeyNames="EndUserId" AllowPaging="True"
                    OnItemCommand="ListView1_ItemCommand" OnItemCanceling="ListView1_ItemCanceling">

    <EditItemTemplate>
        <tr>
            <asp:Label runat="server" ID="tbId" Text='<%#Eval("EndUserId") %>' Visible="false" />
            <td>
                <asp:TextBox runat="server" ID="tbEmail" Text='<%#Eval("Email") %>' />
            </td>
            <td>
                <asp:TextBox runat="server" ID="tbRole" Text='<%#Eval("Role") %>' />
            </td>
            <td>
                <asp:LinkButton ID="lnkUpdate" runat="server" CommandName="Update">Update</asp:LinkButton>
                <asp:LinkButton ID="lnkCancel" runat="server" CommandName="Cancel">Cancel</asp:LinkButton>
            </td>
        </tr>
    </EditItemTemplate>

c＃后端控制

    protected void ListView1_ItemCanceling(object sender, ListViewCancelEventArgs e)
    {
        ListView1.EditIndex = -1;
        ListView1.DataBind();      
    }

protected void Page_Load(object sender, EventArgs e)
        {
            ListView1.EditIndex = -1;
            ListView1.InsertItemPosition = InsertItemPosition.LastItem;

            if (!IsPostBack)
            {

            }
        }

添加了后端

protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
        {
            if (e.CommandName == "Update")
            {
                Label tbId = (Label)e.Item.FindControl("tbId");
                TextBox tbEmail = (TextBox)e.Item.FindControl("tbEmail");
                TextBox tbPass = (TextBox)e.Item.FindControl("tbPass");

                string updateCommand =
                    "UPDATE [EndUser_tbl] SET [Email]='" +
                    tbEmail.Text + "', [Password]='" + tbPass.Text +
                    "'WHERE EndUserId=" + Convert.ToInt32(tbId.Text) + ";";
                sqlDatasource1.UpdateCommand = updateCommand;
            }
            if (e.CommandName == "Delete")
            {
                Label id = (Label)e.Item.FindControl("tbId");
                string deleteCommand = "DELETE FROM [EndUser_tbl] " +
                        "WHERE EndUserId=" + Convert.ToInt32(id.Text);
                sqlDatasource1.DeleteCommand = deleteCommand;
            }
            if (e.CommandName == "Insert")
            {
                TextBox tbEmail = (TextBox)e.Item.FindControl("tbEmail");
                TextBox tbPass = (TextBox)e.Item.FindControl("tbPass");


                string insertCommand = "INSERT INTO [EndUser_tbl] " +
                        "([Email],[Password],[ContractRef],[Role])" +
                        "VALUES ('" + tbEmail.Text + "','" + tbPass.Text + 
                            "','" + tbPass.Text + "');";

                sqlDatasource1.InsertCommand = insertCommand;
            }
        }

像这样改变Page_load：

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
             ListView1.EditIndex = -1;
             ListView1.InsertItemPosition = InsertItemPosition.LastItem;
        }
    }

再试一次。
