How to use jquery function with asp.net textbox

asked Sep 25, 2014 by justin-tartagni

This jquery function works great for me as a dropdown list that fills the input box upon selection.

my problem is that I want to use an ASP.net textbox rather than the input box.(mainly to refer to it when I click the "submit" button) when I exchange the two my dropdown function no longer works.

Thanks for the help

<head>
  <meta charset="utf-8">
  <title>jQuery UI Autocomplete - Scrollable results</title>
  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css">

    overflow-y: auto;
    /* prevent horizontal scrollbar */
    overflow-x: hidden;
  }

  /* IE 6 doesn't support max-height

   * we use height instead, but this forces the menu to always be this tall

  * html .ui-autocomplete {

Either use:

<asp:TextBox id="tags" ClientIDMode="static" runat="server" />

Which will generate the clientID to be the same as the id you have set, or

<asp:TextBox id="tags" runat="server" />

and use the jquery selector like

$("#<%= tags.ClientID %>").autocomplete({......

If id is the problem then try assigning a dummy class for the textbox and reference the control using the class name. Upon Submit button click you will be able to access the tags textbox server control.

<asp:TextBox id="tags" runat="server" class ="txtauto" />

Then in your JS

$(".txtauto").autocomplete({
       source: availableTags
});
