//问题刷新值   代码隐藏文件动态创建一个复选框,aspx文件包含调用的javascript 选中该复选框时,请参阅以下内容:

// java描述

function checkBoxClicked(sender) 
{
  var hdnfldVariable = document.getElementById('hcompare');

  if (sender.checked == true) {
     sCompareAuditVersion = sender.value;
     }
        document.getElementById('hcompare').value = sCompareAuditVersion;
}

// aspx文件 -  我使用隐藏字段传递给文件后面的代码并使用' x'初始化值。至 //确保值更改

<form id="form1" runat="server">
<div class="lowSectionClass">
   <asp:HiddenField id="hcompare" value="X"  runat="server">
    </asp:HiddenField>

//代码隐藏文件动态构建chekbox

public class Report : Page
    {
    protected HiddenField hcompare; 

    private string populateCalculations(int tabID, int programID, int participantID)
      {
        string str = "";
        str = ((((str + "<br /><br /><center><table cellpadding='0' cellspacing='10'>" + "<tr class='HeadingCellText'>") + "<td>Audit Version</td>" + "<td></td>") + "<td>Calculation Set</td>" + "<td></td>") + "<td>Run Calcs/Print Report/Print CSB</td>" + "<td></td>") + "<td>Compare?</td>" + "</tr>";
        DataTable infoList = new DataTable();
        infoList = new ReportClass().GetInfoList(programID);
        if (infoList.Rows.Count > 0)
        {
            for (int i = 0; i < infoList.Rows.Count; i++)  // 1 = a audit, 2 = b audit, 3 = c audit.....
            {
                if ((i % 2) == 0) //audit 'a' = 0, audit 'b' = 1
                {
                        str = string.Concat(new object[] { str, "<td>", infoList.Rows[i]["dtCalcDate"], "</td>" }) + "<td></td>";
                       str = string.Concat(new object[] { str, "<td><a href=\"javascript:runCalcs('", programID, "','", infoList.Rows[i]["sAuditVersion"].ToString(), "');\">Run Calcs</a> | <a href=\"javascript:setPrintVariables(", programID, ",", participantID, ",'",

                         }) + "<td></td>";
    // above is where the hidden field is assigned to be passes in as a parameters and the value is not being updated
    // below is where the checkbox is created and assigned function 'checkBoxClicked(this)'
                       str = string.Concat(new object[] { str, "<td><input id='Checkbox", i, "' tabindex='", i, "' value='", infoList.Rows[i]["sAuditVersion"].ToString(), "' onclick='checkBoxClicked(this)' type='checkbox' /></td>" }) + "</tr>";
                    }
                }
                }
              return (str + "</tfoot>" + "</table></center>");
    }

为隐藏字段设置clientidmode = static

<form id="form1" runat="server">
<div class="lowSectionClass">
<asp:HiddenField id="hcompare" value="X" clientIdMode="static" runat="server">
</asp:HiddenField>
</div>
</form>
