title: Textbox.textchanged event in asp.net using vb.net
body: <p>so on my webpage i have the following textbox </p>
  
  <pre><code>&lt;asp:TextBox ID="txtFiltrarNomeUtente" runat="server" AutoPostBack="true" OnTextChanged="txtFiltrarNomeUtente_TextChanged"&gt;
  </code></pre>
  
  <p>and the handler</p>
  
  <pre><code>Protected Sub txtFiltrarNomeUtente_TextChanged(sender As Object, e As EventArgs) Handles txtFiltrarNomeUtente.TextChanged
    (code...)
  End Sub
  </code></pre>
  
  <p>and this is working fine, but i noticed that the textchanged event only triggers  after the user writed text and press enter or mouse click.So with this said i wanted to know if its possible to make a postback for the event to trigger everytime the text is changed, like everytime the user press a key without having to press enter or mouse click? thanks in advance</p>
