Hi,<br />
<br />
You can do using the OnTextChanged event on Text box. And you can handle Page partial rendering using <br />
<br />
&nbsp;&lt;asp:ScriptManager ID=&quot;ScriptManager1&quot; runat=&quot;server&quot; EnablePartialRendering=&quot;tr<wbr />ue&quot; /&gt;<br />
&lt;asp:AsyncPostBackTrigger&gt;<wbr />
</div>


Hi,

You can do using the OnTextChanged event on Text box. And you can handle Page partial rendering using

 <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<asp:AsyncPostBackTrigger>

<div>
Don't use :<br />
&lt;asp:Panel id=&quot;p1&quot; runat=&quot;server&quot; Enabled=&quot;false&quot;&gt;<br />
but:<br />
&lt;asp:Panel id=&quot;p1&quot; runat=&quot;server&quot; style=&quot;display:none&quot;&gt;<br />
<br />
Now you can use :<br />

<pre><code id="code-20-38283909-1">$(&quot;#&lt;%= txtreceivingreport.ClientID %&gt;&quot;).keyup(function() {
     if( $(this).val().length&gt;0 ) $(&quot;#&lt;%= p1.ClientID %&gt;&quot;).show();
})</code></pre>
</div>


Don't use :
<asp:Panel id="p1" runat="server" Enabled="false">
but:
<asp:Panel id="p1" runat="server" style="display:none">

Now you can use :


$("#<%= txtreceivingreport.ClientID %>").keyup(function() {
     if( $(this).val().length>0 ) $("#<%= p1.ClientID %>").show();
})

<div>
<div class="content wysiwyg-content">
I have the following code,<br />
&lt;asp:TextBox id=&quot;txtreceivingreport&quot; Text=&quot;&quot; runat=&quot;server&quot;&gt;<br />
&lt;asp:Pane<br />
I want when the user enters the anything in textbox, the panel should be enabled<br />
&lt;asp:Panel id=&quot;p1&quot; runat=&quot;server&quot; Enabled=&quot;false&quot;&gt;<br />
&lt;asp:RadioButton id=&quot;rbmale&quot; runat=&quot;server&quot; Text=&quot;Male&quot;&gt;<br />
&lt;asp:RadioButton id=&quot;rbfemale&quot; runat=&quot;server&quot; Text=&quot;FeMale&quot;&gt;<br />
&lt;/asp:Panel&gt;
</div>
</div>


I have the following code,
<asp:TextBox id="txtreceivingreport" Text="" runat="server">
<asp:Pane
I want when the user enters the anything in textbox, the panel should be enabled
<asp:Panel id="p1" runat="server" Enabled="false">
<asp:RadioButton id="rbmale" runat="server" Text="Male">
<asp:RadioButton id="rbfemale" runat="server" Text="FeMale">
</asp:Panel>

How to enable disable panel using jquery.

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.
