ajax的AsyncPostBackTrigger没效果

[chenydong]

<div id="div6" runat="server" style= "height:auto;width:auto; text-align: left;">
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="tbRegisterID0" runat="server" Width="58px"
ontextchanged="tbRegisterID_TextChanged" TabIndex="2" AutoPostBack="True"></asp:TextBox>

<asp:TextBox ID="tbPatientID" runat="server"
ontextchanged="tbPatientID_TextChanged" AutoPostBack="True" TabIndex="3"></asp:TextBox>

</ContentTemplate>
</asp:UpdatePanel>
</div>

<div id="div4" runat="server" style= "height:350px;width:auto; text-align: left;">
<asp:UpdatePanel ID="UpdatePanel4" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:PostBackTrigger ControlID="btnNext" />
<asp:AsyncPostBackTrigger ControlID="tbRegisterID0" />
<asp:AsyncPostBackTrigger ControlID="tbPatientID" />
</Triggers>
<ContentTemplate>
<asp:GridView ID="gvKindList" Runat="server" >
......
</ContentTemplate>
</asp:UpdatePanel>
</div>

为什么tbRegisterID0的TextChanged事件不会触发GridView 的更新

EventName没写
<asp:AsyncPostBackTrigger ControlID="tbRegisterID0" EventName="TextChanged" />
