 如果单击LinkButton 想获取当前HiddenField 中的值。

Answer 1

asp.GridView的ItemCommand事件中：
HiddenField hide = e.Item.FindControl("hidAppNo") as HiddenField;
if(hide != null){
    // 操作hide吧
}

Answer 2

js可以获取到
function Get(obj)
{
   var hide = obj.parentNode.childNodes[0].value;
   alert(hide);
}
                <asp:TemplateField HeaderText="状态">
                    <ItemTemplate>
                        <asp:HiddenField ID="hidAppNo" runat="server" Value='<%#Eval("FEATUREAPPNO")%>'/>
                        <asp:LinkButton ID="linkbtnLock" runat="server" OnClientClick="Get(this)">解锁座位</asp:LinkButton>
                        <asp:Label ID="lblLock" runat="server" Text="&nbsp;" Visible="false"></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
