WPF DataGrid Pagination

Question

I am using the example provided here StackOverflow related question, if i have an even number of items in the grid then it works all good, but if for instance i have an odd

Answer 1

The issue is not with GetItemAt method, leave it as it was:

    public override object GetItemAt(int index)
    {
        var offset = index % (this._itemsPerPage); 

        return this._innerList[this.StartIndex + offset];
    }

The problem is with Count property override. In case it is the last page it should return the correct items left:

    public override int Count
    {
        get 
        {
            //all pages except the last
            if (CurrentPage < PageCount)
                return this._itemsPerPage;

            //last page
            int remainder = _innerList.Count % this._itemsPerPage;

            return remainder == 0 ? this._itemsPerPage : remainder; 
        }
    }
