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
