the javascript im using...
function CheckOnes(spanChk){
var oItem = spanChk.children;
var theBox= (spanChk.type=="radio") ?
spanChk : spanChk.children.item[0];
xState=theBox.unchecked;
elm=theBox.form.elements;
for(i=0;i<elm.length;i++)
if(elm[i].type=="radio" &&
elm[i].id!=theBox.id)
{
elm[i].checked=xState;
}
}
iam getting an error like this
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
