Possible to cancel paging in ListView using DataPager

Question

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}
} 

Does anyone know if canceling the paging is possible and how to perform it? Thanks

I too was disappointed to find there was no simpler way to do this. I ended up very much like Littlefool, where I made use of the PagePropertiesChanging event. In it, if my validation did not pass, I called the SetPageProperties() on my DataPager with a saved off value of its previous StartRowIndex value, which I save off in the ViewState.

Not my proudest solution but it works.
