Search gridview based on the value typing in textbox?
<p>I am using ASP.NET and C#.This is my code.</p>

<pre><code>&lt;asp:UpdatePanel ID="gridSearch" runat="server"&gt;
   &lt;ContentTemplate&gt;
      &lt;asp:GridView ID="jobcardSearch" runat="server"&gt;                     
          &lt;Columns&gt;
             &lt;asp:TemplateField&gt;                
                &lt;HeaderTemplate&gt;                                                
                   &lt;asp:LinkButton ID="LinkButton1" Text="First Name"
                   CommandName="sort" CommandArgument="FirstName" 
                   runat="server"&gt;&lt;/asp:LinkButton&gt;                                                                 
                   &lt;asp:TextBox ID="search" runat="server" Width="70px"&gt;&lt;/asp:TextBox&gt;
               &lt;/HeaderTemplate&gt;
               &lt;ItemTemplate&gt;
                  &lt;%# Eval("FirstName")%&gt;
               &lt;/ItemTemplate&gt;
             &lt;/asp:TemplateField&gt;       
           &lt;/Columns&gt;
        &lt;/asp:GridView&gt;
   &lt;/ContentTemplate&gt;
&lt;/asp:UpdatePanel&gt;
</code></pre>

<p>So while typing on the textbox, I need to filter the grid then I need to perform this without postback.</p>
