UpdatePanel rerenders form
<p>I have a ascx that looks like this:</p>

<pre><code>&lt;UpdatePanel Parent mode = Conditional&gt;
  &lt;UpdatePanel1 mode = Conditional&gt;
    //A form here with textboxes, etc

    //A repeater here with a linkbutton that causes a postback

  &lt;/UpdatePanel1&gt;
&lt;/UpdatePanel Parent&gt;
</code></pre>

<p>In the OnItemCommand of the repeater, I get the form values and set them. It works fine but there is re-rendering of the form (ie., a flicker during which the form disappears and reappears). Why is this happening considering i have it in an UpdatePanel?</p>

<p><strong>EDIT:
I seem to have half solved the problem by separating the form and the repeater into its different updatepanels. But, the problem now is that the form doesnt get updated when I click on the linkbutton in the repeater even though the server side code runs.</strong></p>

<p>EDIT AGAIN:</p>

<p>I think I know what's going on. I have 1 question before nailing this (hopefully). The form looks like this:</p>

<pre><code>&lt;tr&gt;
  &lt;td&gt;
    &lt;asp:checkbox id="chkSelect" runat="server" /&gt;
    &lt;asp:label text="Something"   runat="server" /&gt;
    &lt;asp:textbox id="txtSomething" runat="server" /&gt;
  &lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
  &lt;td&gt;
    &lt;asp:checkbox id="chkSelect2" runat="server" /&gt;
    &lt;asp:label text="Something2"   runat="server" /&gt;
    &lt;asp:textbox id="txtSomething2" runat="server" /&gt;
  &lt;/td&gt;
&lt;/tr&gt;
</code></pre>

<p>All I care about when the linkbutton is clicked is to update ONLY the textbox controls. I want everything else to remain the way they were.</p>

<p>Is there a way to conditionally trigger updates only on those controls?</p>

<p>I understand I can use JS but would rather avoid it (as there's a lot of server side processing before I know the values of the textboxes)</p>

<p><strong><em>@Roselberg - The state of the controls that I am NOT interested in, is actually set on the client side in one huge JS script that runs on load to which I really don't have much control over the script</em></strong></p>
