Dynamic TextField KeyUP Event

[archana]

Hiii


I am using Ext.Net's Control in my WebSite.
I am creating Dynamic TextField and add it into EXT.Window but I cant call KeyUp Listener of that TextField....

TextField txt= new TextField ();

var win = new Window()
{
ID = MenuID,
Title = MenuName,
Height = 264,
Width = 221
};.

txt = new TextField() { ID = "txtEnterMessage1", EnableKeyEvents=true, Enabled = false, Text = "Hiii", Width = 207 };
txt.Listeners.KeyUp.Handler = "MessageSend(this.getValue()).toString()";

Problem In this Line

win.Items.Add(txt);
win.Render(this);





If any 1 tried out this then please send me code
