How do I use an extended control in a ASPX page??????

[eqttester]

SearchTextField.js

Ext.namespace('Ext.ux.form');

Ext.ux.form.SearchTextField = function (config) {
    Ext.ux.form.SearchTextField.superclass.constructor.call(this, config);
};

Ext.ux.form.SearchTextField = Ext.extend(Ext.form.TextField, {

    searchModeEnabled: true,
    failureFn: null,
    successFn: null,
    searchUrl: null,
    extraParameterName: 'identificador',

    initComponent: function () {
        Ext.ux.form.SearchTextField.superclass.initComponent.call(this);
    },

    // private
    initEvents: function () {
        Ext.ux.form.SearchTextField.superclass.initEvents.call(this);
    },

    onRender: function (ct, position) {
        Ext.ux.form.SearchTextField.superclass.onRender.call(this, ct, position);
    }
});

Ext.reg('searchtextfield', Ext.ux.form.SearchTextField);

How do I use this control in my ASPX page?

<script type="text/javascript" src="SearchTextField.js"></script>

Using the following anywhere

<ext:searchtextfield runat="server" id="gg"></ext:searchtextfield>

I get the error
Unknown server tag 'ext:searchtextfield'.

Hi,

A JavaScript class is not enough to use it as Asp.Net server control.

You should create a C# wrapper class and attach it to a page like this (or in web.config)

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

You should set up respective Assemblyand Namespace.

You can extend the Ext.Net.TextField class.

You will need to override .InstanceOf and .XType properties.

Here is some manual.
