Are you seeing an ArgumentOutOfRangeException or just curious about the setting?  We have not seen an exception in our testing.  When the control is initialized it does set the PageIndex to -1; it will be reset to 0 when the page load logic is entered.

By design EntityQueryPagedCollectionView.PageIndex  may be set to -1 (for example when objectDataSource.Load() called twice), but DataPager from SL toolkit wont only >=0 numbers (raise ArgumentOurOfRangeException). 


private void InitFields()

{

    this._queryPageMap.Clear();

    this._requestedPageLoading.Clear();

    this.CurrentItem = null;

    this.CurrentPosition = -1;

    this.PageIndex = -1;  //!!!

}


Is it bug or design feature ?
