使用Datalist ItemDataBound获取下拉选择的值

Question

我正在尝试使用Datalist OnItemDataBound获取Dropdownlist选择的值
DlSubjects是主DataList，dlTests是嵌套的DataList。 dlSubjects中包含下拉列表。

我的代码：

protected void dlSubjects_ItemDataBound(object sender, DataListItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        DataList dlTests = e.Item.FindControl("dlTests") as DataList;
        DropDownList drpTopic = e.Item.FindControl("drpTopic") as DropDownList;

        string Value = drpTopic.SelectedValue;
    }
}

任何人都可以帮我这个???

我太晚了，但我现在正在做同样的事，如果我是对的，那么我认为答案应该是这样的：

protected void dlSubjects_ItemDataBound(object sender, DataListItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        DataList dlTests = e.Item.FindControl("dlTests") as DataList;
        DropDownList drpTopic = e.Item.FindControl("drpTopic") as DropDownList;

        string Value = ((DataRowView)e.Item.DataItem).Row.ItemArray[index].ToString(); //index is your dropdown index in the datalist
    }
}
