我正在尝试将控件添加到以前只读的页面。环境是：
- SharePoint 2010 解决方案
- 在 Visual Studios 2010 中开发
- 此功能位于 Web 部件上 (AceAllocation30.cs)
- 代码是 C#
这是我添加的代码：
sb.Append(" <td width=\"75%\">"); lc3 = new LiteralControl(sb.ToString()); Controls.Add(lc3); TextBox JDHFTxt = new TextBox(); JDHFTxt.ID = "txtJDHF"; JDHFTxt.Enabled = true; JDHFTxt.Value = ConvertToAllocation(DrACE["SPRAmount"].ToString()); Controls.Add(JDHFTxt); sb = new StringBuilder();
sb.Append("</td>");
上面添加的代码替换了此代码：
sb.Append(" <td class=\"rowText\" width=\"75%\">" + ConvertToAllocation(DrACE["SPRAmount"].ToString()) + "</td>");
为了更完整的参考，上面的完整原始部分是这样的：
sb.Append(" <tr class=\"row2\">");
sb.Append(" <td class=\"rowTextLeft\" width=\"25%\">SPR/JDHF Allotment:</td>");
sb.Append(" <td class=\"rowText\" width=\"75%\">" + ConvertToAllocation(DrACE["SPRAmount"].ToString()) + "</td>");
sb.Append(" </tr>");
但是当我部署时，出现以下错误：
错误 35；“System.Web.UI.WebControls.TextBox”不包含“Value”的定义，并且找不到接受“System.Web.UI.WebControls.TextBox”类型的第一个参数的扩展方法“Value”（你是缺少 using 指令或程序集引用？）
错误 32；当前上下文中不存在名称“lc3”
错误 33；当前上下文中不存在名称“lc3”
这是完整的页面代码：
