AJAX HoverMenuExtender expands/displays on page load
<p>Anybody help me to resolve this issue ?
I am displaying one grid on hover of linkbutton using AJAX hovermenu extender.
But when page is loading first time or on postback, that grid is displaying.</p>

<p>Below is the code:</p>

<pre><code>&lt;asp:LinkButton ID="lnkItm" runat="server" Text="Click"&gt;&lt;/asp:LinkButton&gt;
&lt;AjaxToolKit:HoverMenuExtender ID="hme2" runat="Server" TargetControlID="lnkItm"
PopupControlID="PopupMenu" HoverCssClass="popupHover" PopupPosition="Right" OffsetX="0"
OffsetY="0" PopDelay="50" /&gt;
&lt;asp:Panel CssClass="PopupMenu" ID="PopupMenu" runat="server"&gt;
&lt;asp:GridView ID="grd" runat="server" Width="100px" AutoGenerateColumns="False"&gt;
&lt;Columns&gt;
...
&lt;/Columns&gt;
&lt;/asp:GridView&gt;
&lt;/asp:Panel&gt;
</code></pre>

<p>Please let me know how to resolve this issue.</p>
