动态往table中添加行，行的对应列中含有DropDownList 服务器控件，怎么绑定数据到该控件
ASP.NET+c#
代码如下：
实现动态添加行的JS代码如下
function addRow(tabObj, colNum, targPos) {
var sorPos = parseInt("<%=GetLinCount()%>") + 4;
var IDTab = String(sorPos);
var nTR = tabObj.insertRow(tabObj.rows.length - targPos);
var TRs = tabObj.getElementsByTagName('tr'); // Get TRs collection from the appointed table
var sorTR = TRs[sorPos]; // Positioned the sorTR
var TDs = sorTR.getElementsByTagName('td');
if (colNum == 0 || colNum == undefined || colNum == isNaN) {
colNum = tabObj.rows[4].cells.length;
}
var ntd = new Array(); // Create a new TDs array
for (var i = 0; i < colNum; i++) {
ntd[i] = nTR.insertCell();
if (0 == i) {
ntd[i].style.cssText = "BORDER-TOP: #168bd9 2px solid;BACKGROUND-COLOR: #168bd9";
}
else {
if (1 == i) {
ntd[i].id = "name" + IDTab;
}
if (2 == i) {
ntd[i].id = "version" + IDTab;
}
}
ntd[i].innerHTML = TDs[i].innerHTML; // copy the value in ntd[i]'s innerHTML from corresponding TDs
}
}
function deleteRow(tabObj,btnObj) { //Remove table row
var targPos = parseInt("<%=GetLinCount()%>") + 4;
for (var i = 0; i < tabObj.rows.length; i++) {
if (tabObj.getElementsByTagName('label')[i] == btnObj) {
tabObj.deleteRow(i + targPos);
}
}
}
<tr id="AddNewRow" style="display:none;">
<td id="FirstId" style="background-color:#168bd9;border-top:none;"></td>
<td><asp:DropDownList ID="AddName_DDList" runat="server" Width="100%"></asp:DropDownList></td>

<td><label><asp:Button ID="AddDelete_Button" runat="server" Width="100px" Text="Delete" OnClick="AddDelete_Button_Click" OnClientClick="return deleteRow(document.all.tabUserInfo, this.parentNode)" /></label></td>
