Hi Timothy,
The <Change> Listener and AjaxEvent has been added to the <ext:Hidden> Field control.
The following sample demonstrates using a <Click> Listener on an <ext:Button> to set the value of a <ext:Hidden> field, which then automatically fires a <Change> AjaxEvent. Within the Hidden1_Change event on the server I set the .Text property of an <ext:Label>.
Example
<%@ Page Language="C#" %>
<%@ Register assembly="Coolite.Ext.Web" namespace="Coolite.Ext.Web" tagprefix="ext" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Hidden1_Change(object sender, AjaxEventArgs e)
{
this.Label1.Text = "The HiddenField was updated: " + this.Hidden1.Value.ToString();
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
</head>
<body>
<p><a href="AjaxEvent.aspx">Reload</a></p>
<form id="form1" runat="server">
<ext:ScriptManager ID="ScriptManager1" runat="server" />
<ext:Hidden ID="Hidden1" runat="server">
<AjaxEvents>
<Change OnEvent="Hidden1_Change" />
</AjaxEvents>
</ext:Hidden>
<ext:Button
ID="Button1"
runat="server"
Text="Submit"
AutoPostBack="false">
<Listeners>
<Click Handler="#{Hidden1}.setValue('Testing...');" />
</Listeners>
</ext:Button>
<ext:Label ID="Label1" runat="server" />
</form>
</body>
</html>
Thanks for pointing out this functionality was missing.
Hope this helps.
