body: <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>
