C# 在回发时保留动态内容

我有一个默认情况下如下所示的表：

<table width="650" id="myTable" runat="server">
    <tbody>
        <tr>
            <td class="cellWidth300 bottomBorder topBorder">Column1</td>
            <td class="cellWidth125 leftBorder topBorder bottomBorder textCenter">Column2</td>
            <td class="cellWidth100 leftBorder topBorder bottomBorder textCenter">Column3</td>
            <td class="cellWidth125 leftBorder rightBorder topBorder bottomBorder textRight">Column4</td>
        </tr>
        <tr>
            <td class="cellWidth300"><input type="text" size="29" runat="server"/></td>
            <td class="cellWidth125 leftBorder textCenter"><input type="text" size="9" class="units commas" runat="server"/></td>
            <td class="cellWidth100 leftBorder textCenter"><input type="text" size="8" class="value commas" runat="server"/></td>
            <td class="cellWidth125 leftBorder rightBorder textRight"><input type="text" size="11" readonly="readonly" tabindex="-1" class="totalA1 autoTotal" runat="server"/>&nbsp;</td>
        </tr>
        <tr>
            <td class="cellWidth300"><input id="Text2" type="text" size="29" runat="server"/></td>
            <td class="cellWidth125 leftBorder textCenter"><inputtype="text" size="9" class="units commas" runat="server"/></td>
            <td class="cellWidth100 leftBorder textCenter"><input  type="text" size="8" class="value commas" runat="server"/></td>
            <td class="cellWidth125 leftBorder rightBorder textRight"><input type="text" size="11" readonly="readonly" tabindex="-1" class="totalA1 autoTotal" runat="server"/>&nbsp;</td>
        </tr>

        </tr>
    </tbody>
</table>

var _addRow ='<tr>' +

private void WriteMyTableToXML()

    HtmlTableRow tRow;

    int i = 1; //First row is headers, which we don't want.

    _Writer.WriteStartElement("MyTable");

    while (i < tblCropsAndFeed.Rows.Count - 1) // last row should always be blank.  We can skip it
    {
        tRow = tblCropsAndFeed.Rows[i];

        _Writer.WriteStartElement("Entry");

        string tInputBox0 = tRow.Cells[0].Controls[0].ClientID;
        tContent = (HtmlInputText)tRow.FindControl(tInputBox0);
        _Writer.WriteStartElement("name");
        _Writer.WriteString(tContent.Value);

    _Writer.WriteEndElement();

因此，我认为最好的选择是使用带有服务器端绑定的ASP GridView。当您编辑或向gridview添加行时，它将在回发时使用您从创建的XML文件提供的数据自动重建

您是否加载任何初始数据，或者它只是没有绑定的纯html和.NET控件？它只是没有绑定的纯html和.NET控件。您是否每次都写入同一个xml文件？正如您一直在覆盖或附加数据一样？该程序允许您命名数据，因此用户可以选择创建新数据或覆盖现有数据。您以前使用过gridview控件吗？在代码隐藏中使用绑定？

If(IsPostBack)
    {
    DontResetThePage();
    }
