LinkBut​​ton的ListView中的UpdatePanel中导致完全回发

我有一个LinkBut​​ton在一个UpdatePanel一个ListView。我想按钮（当然，其中的任何）造成局部回传，但他们所造成的一整页回发。

I have a LinkButton in a ListView in an UpdatePanel. I would like the button (well, any of them) to cause a partial postback, but they are causing a full page postback.

<asp:UpdatePanel ID="upOutcomes" UpdateMode="Conditional" runat="server">
  <ContentTemplate>
      <asp:ListView ID="lvTargets" runat="server" onitemdatabound="lvTargets_ItemDataBound">
        <ItemTemplate>
          <asp:LinkButton ID="lnkAddTarget" CssClass="lo" Text='<%# Eval("Title") + " <b>" + Eval("Level") + Eval("SubLevel") + "</b>" %>' runat="server"></asp:LinkButton>
        </ItemTemplate>
      </asp:ListView>
  </ContentTemplate>
</asp:UpdatePanel>

我发现计算器另一个帖子里面建议增加这样的：

I found another post on stackoverflow which suggested adding this:

protected void lvTargets_ItemDataBound(object sender, ListViewItemEventArgs e) {
  var lb = e.Item.FindControl("lnkAddTarget") as LinkButton;
  tsm.RegisterAsyncPostBackControl(lb);  // ToolkitScriptManager
}

这还没有做出区别...

It hasn't made a difference...

有一些其他类似的帖子太多，但我不能找到一个解决办法！任何想法？

There are a few other similar posts too, but I can't find a solution! Any ideas?
