Cancel Paging In ListView Using DataPager?

I'm using a datapager control on my listview to perform paging in it.

When paging through the table, I need to perform some validations. When these validations are not successfull, the paging should be cancelled.

I currently perform the validation in the PagePropertiesChanging event of the ListView, however, the arguments do not provide a Cancel property.

protected void MyListView_PagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e)
{
if (!Validate())
{ // cancel the paging action}
}
