WebCustomControl Problem

[Hemant]

Hi,

I have created a webcostomcontrol and add one property "Xyz". That
custome control is inherited from TextBox class.

[Bindable(true)]
[Category("Appearance")]
[DefaultValue("")]
[Localizable(true)]
public string Xyz
{
get
{
String s = (String)ViewState["Xyz"];
return ((s == null) ? String.Empty : s);
}
set
{
ViewState["Xyz"] = value;
}
}


and i have set the value for Xyz from client script like

<script Language='javascript'>
function setvalue()
{
form1.txt.Xyz = "Some Text";
}
</script>

on postback i want the value which is set from clientscript.
but i cant get the updated value for Xyz.
Is there another way to set the value from clientscript and get it at
serverside?
Or we cant get the value which is set by client script. do i need to
use hidden textbox to get the value?

Thanx in advance.

Hemant Mane.
