Perform at same time javascript and asp.net rendering
<p>Suppose I have a <code>.gif</code>:</p>

<pre><code>&lt;img alt="" src="./wait.gif" /&gt;
</code></pre>

<p>And I have a Label:</p>

<pre><code>&lt;asp:Label ID="tbnotif" runat="server" ReadOnly="True" Text="" &gt;&lt;/asp:Label&gt;
</code></pre>

<p>And a button:</p>

<pre><code>&lt;asp:Button ID="Button1" runat="server" Text="Pubblica" OnClientClick="show_table();add_gif();" OnCommand="Button1_Click" /&gt;
</code></pre>

<p>I'm using aspx pages, the question is:</p>

<p>Can I click on the button and at same TIME show the <code>.gif</code> with JavaScript and change the Label from code behind? Or will things never be shown at same time?</p>
