Asp.net Telerik script issue - asp.net

Question

I have a line of code which comes inside a Telerik.Web.UI.Webresource.axd file which breaks something in my custom code.
dataBind:function(){if(this._virtualization&&!this._virtualization._isDataBinding&&((this.get_allowPaging()&&this._dataSource.length>this.get_pageSize())||(!this.get_allowPaging()&&this._dataSource.length>this._virtualization._itemsPerView))){this._virtualization._startIndex=null;
this._virtualization.set_bindingType("Client");
this._virtualization.set_cachedData(this._dataSource);
this._virtualization.set_virtualItemCount(this._dataSource.length);
this._virtualization.select();
return;
}
**Array.forEach($telerik.getElementsByClassName(this.get_element().tBodies[0],"rgGroupHeader"),function(i){i.parentNode.removeChild(i)**;
});
I would like to know if it is possible to prevent the below line of code to be executed
Array.forEach($telerik.getElementsByClassName(this.get_element().tBodies[0],"rgGroupHeader"),function(i){i.parentNode.removeChild(i)**;

You can override the dataBind method of RadGrid which will allow you to customize it:
<script>
Telerik.Web.UI.GridClientSideBinding.prototype.dataBind = function () {
// Virtualization
if (this._virtualization && !this._virtualization._isDataBinding &&
((this.get_allowPaging() && this._dataSource.length > this.get_pageSize()) ||
(!this.get_allowPaging() && this._dataSource.length > this._virtualization._itemsPerView))) {
this._virtualization._startIndex = null;
this._virtualization.set_bindingType("Client");
this._virtualization.set_cachedData(this._dataSource);
this._virtualization.set_virtualItemCount(this._dataSource.length);
this._virtualization.select();
return;
}
Array.forEach($telerik.getElementsByClassName(this.get_element().tBodies[0], "rgGroupHeader"), function (element) {
element.parentNode.removeChild(element);
});
Array.forEach($telerik.getElementsByClassName(this.get_element().tBodies[0], "rgFooter"), function (element) {
element.parentNode.removeChild(element);
});
var noRecordsItem = $telerik.getElementByClassName(this.get_element(), "rgNoRecords");
if (noRecordsItem) {
if (this._dataSource.length > 0) {
noRecordsItem.style.display = "none";
} else {
noRecordsItem.style.display = "";
this._setPagerVisibility(this._data.PagerAlwaysVisible);
}
}
var dataItems = this.get_dataItems();
var columns = this.get_columns();
var i, l1, l2;
var tableElement = ($telerik.isOpera) ? this.get_element() : this.get_element().tBodies[0];
if (this._dataSource.length < dataItems.length || tableElement.rows.length == 1) {
for (i = 0, l1 = dataItems.length; i < l1; i++) {
dataItems[i].set_visible(false);
dataItems[i].get_element().style.display = "none";
}
this._cacheDataItems();
}
this._dataBind(this._dataSource);
var firstSelection = true;
// When YahooStyleScrolling is used in RadGrid and user
//scrolls down, select multiple rows using shift + down arrow key,
//the selection is not persisted on next page load
if (this._owner._keyboardNavigationProperties) {
firstSelection = this._owner._keyboardNavigationProperties.firstSelection;
}
var owner = $find(this._owner.get_id());
if (owner._getPositionedDataItems) {
owner._getPositionedDataItems(true);
}
if (this._owner._keyboardNavigationProperties) {
this._owner._keyboardNavigationProperties.firstSelection = firstSelection;
}
this._fixRowsClassNames();
this._owner.raise_dataBound(Sys.EventArgs.Empty);
for (i = 0, l2 = columns.length; i < l2; i++) {
var isVisible = false;
if (columns[i].get_element().style.visibility != "hidden" && (columns[i].Display == null || columns[i].Display == true) &&
(columns[i]._data.Display == null || columns[i]._data.Display)) {
isVisible = true;
}
if (!isVisible) {
this.hideColumn(i);
}
}
if (this.get_id() == this._owner._masterClientID) {
var grid = $find(this._owner.get_id());
if (grid._scrolling) {
this._owner._scrolling.setHeaderAndFooterDivsWidth();
grid._scrolling._initializeVirtualScrollPaging(true);
}
}
}
</script>
