错误:当前上下文中不存在该名称(Webpart,C#,Visual Studios,SharePoint 2010)

时间:2021-06-18 20:26:42

I am trying to add controls to a page where previously it was read-only. The environment is:

我正在尝试将控件添加到以前只读的页面。环境是:

  • SharePoint 2010 solution
  • SharePoint 2010解决方案

  • Developed in Visual Studios 2010
  • 在Visual Studios 2010中开发

  • This feature is on a webpart (AceAllocation30.cs)
  • 此功能在webpart上(AceAllocation30.cs)

  • The code is C#
  • 代码是C#

Here is the code I added:

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>");

The above added code replaced this code:

上面添加的代码替换了这段代码:

sb.Append("             <td class=\"rowText\" width=\"75%\">" + ConvertToAllocation(DrACE["SPRAmount"].ToString()) + "</td>");

For a more complete reference, the full original segement of the above is this:

有关更完整的参考,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>");

But when I deploy I get the following errors:

但是当我部署时,我得到以下错误:

  • Error 35; 'System.Web.UI.WebControls.TextBox' does not contain a definition for 'Value' and no extension method 'Value' accepting a first argument of type 'System.Web.UI.WebControls.TextBox' could be found (are you missing a using directive or an assembly reference?)

    错误35; 'System.Web.UI.WebControls.TextBox'不包含'Value'的定义,并且没有扩展方法'Value'接受类型'System.Web.UI.WebControls.TextBox'的第一个参数可以找到(你是吗?)缺少using指令或程序集引用?)

  • Error 32; The name 'lc3' does not exist in the current context

    错误32;当前上下文中不存在名称“lc3”

  • Error 33; The name 'lc3' does not exist in the current context

    错误33;当前上下文中不存在名称“lc3”

Here is the full page code:
