title: Filtered Drop Down list items and search in ASP.NET
body: <p>I have a drop down list and when user types something in the same, the drop down list must show the filtered options to be selected. I have done the code behind but filtering is pending.</p>
  
  <pre><code>    &lt;asp:DropDownList ID="AppraisersDpd" runat="server" Width="134px" 
           CssClass="dropdownpersonal textfont" 
           onselectedindexchanged="AppraisersDpd_SelectedIndexChanged" AutoPostBack="true"&gt;&lt;/asp:DropDownList&gt;
  </code></pre>
  
  <p>The code behind is also there which is running:</p>
  
  <pre><code>     AppraisersDpd.DataSource = apprblobj.FillAppraisers();  //fills Appraisers drop down
          AppraisersDpd.DataTextField = "AppraiserName";
          AppraisersDpd.DataValueField = "AppraiserId";
          AppraisersDpd.DataBind();
  </code></pre>
  
  <p>can any one suggests me some clue? Should I use Combo box or I am going right?</p>
