Hi. I moved to ACT 15 and Found this Issue: When Click "Select" other record in Listview items I get Error.
My Page:
```

</html>
```
Error points to:
```
removeHandlers: function(element, events) {
// Removes a set of event handlers from an element
// This is NOT the same as $clearHandlers which removes all delegates from a DomElement. This rather removes select delegates
// from a specified element and has a matching signature as $addHandlers
// "element" - the element to modify
// "events" - the template object that contains event names and delegates
for (var name in events) {
$removeHandler(element, name, events[name]);
}
},
```
in Scripts/WebForms/MsAjax/MicrosoftAjax.js
Can you help me?
