Question

我的页面中有一个表，用户在发送此信息时会列出用户和电子邮件如何使这个表为每个帖子添加一行而不删除其他行？

我的aspx

<table id="tblUsers" class="table table-bordered table-striped">
        <tbody id="tbodyUser">
            <tr>
                <asp:Label ID="lblHeader" Font-Bold="true" runat="server" Visible="false">User to Access</asp:Label>
                <td>
                    <asp:Label ID="lblUser" runat="server" Visible="false"></asp:Label>
                </td>
                <td>
                    <asp:Label ID="lblEmail" runat="server" Visible="false"></asp:Label>
                </td>
            </tr>
        </tbody>
    </table>

我的.cs

protected void btnSendUser_OnClick(object sender, EventArgs e)
{
    string LoginInfo = txtUserAdd.Text;
    PrincipalContext insPrincipalContext = new PrincipalContext(ContextType.Domain, "x.com", "amsndrsecuritysqlser", "xxx");
    UserPrincipal insUserPrincipal = UserPrincipal.FindByIdentity(insPrincipalContext, LoginInfo);


    //it's to first post
    if (lblUser.Visible == false && lblEmail.Visible == false)
    {
        if (insUserPrincipal == null)
        {
            lblError.Visible = true;
        }

        else
        {
            lblUser.Visible = true;
            lblEmail.Visible = true;
            lblHeader.Visible = true;
            lblUser.Text = insUserPrincipal.GivenName + " " + insUserPrincipal.Surname;
            lblEmail.Text = insUserPrincipal.EmailAddress;
        }
    }
}

Answer 1

您必须将runat="server"添加到您的表格tblUsers

var row =new System.Web.UI.HtmlControls.HtmlTableRow();
var cell = new System.Web.UI.HtmlControls.HtmlTableCell();
cell.InnerText = "New Cell";
row.Cells.Add(cell);
tblUsers.Rows.Add(row);

这将是一些可能的解决方案之一：

将数据存储在集合中
在每个按钮中单击，更新数据并将其放入会话
将会话数据绑定到页面中的Repeater（绑定代码必须在Page_Load中）

Repeater标记就是这样的

 <asp:Repeater ID="Repeater1" runat="server">
    <HeaderTemplate>
        <table id="tblUsers" class="table table-bordered table-striped">
            <tbody id="tbodyUser">
    </HeaderTemplate>
    <ItemTemplate>
        <tr>
            <asp:Label ID="lblHeader" Font-Bold="true" runat="server" Visible="<% #lblHeaderVisibilty %>">User to Access</asp:Label>
            <td>
                <asp:Label ID="lblUser" runat="server" Visible="<% #lblUserVisibilty %>"></asp:Label>
            </td>
            <td>
                <asp:Label ID="lblEmail" runat="server" Visible="<% #lblEmailVisibilty %>"></asp:Label>
            </td>
        </tr>
    </ItemTemplate>
    <FooterTemplate>
        </tbody>
    </table>
    </FooterTemplate>
</asp:Repeater>
