Paged Collection View in WPF

问题

Is there an implementation of PagedCollectionView in WPF around? It exists in Silverlight but isn't in WPF.

If there isn't, what would be the simplest way to implement this?

回答1:

You can simply take the code from the Silverlight one and use that in your WPF project.

回答2:

Or use only the CollectionView class and "double filter" your collection

solution found here: Own CollectionView for paging, sorting and filtering

I've pasted the code snipet here for your convinience:

        // obtenir la CollectionView 
        ICollectionView cvCollectionView = CollectionViewSource.GetDefaultView(this.Suivis);
        if (cvCollectionView == null)
            return;

        // filtrer ... exemple pour tests DI-2015-05105-0
        cvCollectionView.Filter = p_oObject => { return true; /* use your own filter */ };

        // page configuration
        int iMaxItemPerPage = 2;
        int iCurrentPage = 0;
        int iStartIndex = iCurrentPage * iMaxItemPerPage;

        // déterminer les objects "de la page"
        int iCurrentIndex = 0;
        HashSet<object> hsObjectsInPage = new HashSet<object>();
        foreach (object oObject in cvCollectionView)
        {
            // break if MaxItemCount is reached
            if (hsObjectsInPage.Count > iMaxItemPerPage)
                break;

            // add if StartIndex is reached
            if (iCurrentIndex >= iStartIndex)
                hsObjectsInPage.Add(oObject);

            // increment
            iCurrentIndex++;
        }

        // refilter
        cvCollectionView.Filter = p_oObject =>
        {
            return hsObjectsInPage.Contains(p_oObject);
        };
