hi tanweer
i tried this before and this will work because of alert method or function but when we remove alert line this will not work
and the reason of this is that error is happening because of postbackif a PostBack occurs, the Label will revert to the original, since Labels changed client-side are not persisted in ViewState. so how can i achieve this after post back is occurred i have diagnosed the error but could not find the treatment
your views on this
thanks

if there is nothing on the serverside on the Button click event then please call the javascript like this.
function ChangeText(){
$("#Label1").html("change");
return false;
}

and the button will look like this:
<asp:Button ID="button1" runat="server" Text="Change Text" OnClientClick="return ChangeText();" />

this will call the javascript method but will not get a postback.
best of luck
