我在我的弹出函数中有一个下拉列表，它没有加载我想要的数据，我已经设置了断点并确认我得到了我想要的数据，但由于某种原因，下拉列表仍然是空的。

C#:
protected void Page_PreRender(object sender, EventArgs e)
{
var nodes = _administrationSystem.GetNodes(); //The dataset with data
var translators = _phonesSystem.GetPhoneNumberTranslators(); //The dataset with data
if (rptList.Items.Count > 0)
{
for (var count = 0; count < rptList.Items.Count; count++)
{
var ddlNodeEdit = (DropDownList)rptList.Items[count].FindControl("ddlNodeEdit");
var ddlTranslatorEdit = (DropDownList)rptList.Items[count].FindControl("ddlTranslatorEdit");
ddlNodeEdit.DataSource = nodes;
ddlNodeEdit.DataTextField = "NodeName";
ddlNodeEdit.DataValueField = "ID";
ddlNodeEdit.DataBind();
ddlNodeEdit.Items.Insert(0, new ListItem("TRNSLTChoose node", "0"));
ddlTranslatorEdit.DataSource = translators;
ddlTranslatorEdit.DataTextField = "Description";
ddlTranslatorEdit.DataValueField = "ID";
ddlTranslatorEdit.DataBind();
ddlTranslatorEdit.Items.Insert(0, new ListItem("TRNSLTChoose numbertranslator", "0"));
