在AJAX.NET 调用Callback方法 的时候，用Content.Value是取不到值的，这是由于在 Callback 时没有调用 FCK.UpdateLinkedField() 方法。在窗体的Load 事件注册一下该方法：protected void Page_Load(object sender, EventArgs e)之后就可以使用Content.Value 获得FCKeditor 的值了。
{
if (!IsPostBack)
{
Page.ClientScript.RegisterOnSubmitStatement(
Content.GetType(),
"editor",
"FCKUpdateLinkedField('" + Content.ClientID + "');");
可以参考：ASP.NET下解决FCKEditor在AJAX中取值问题
