[Solved] How to get all filtered rows ?

[TheRapidOne]

Hi,

I'm looking for a way to get all filtered rows from RadGriwView. I'm using a RadDataPager which pagesize is set to 15. I used the following code, but this one returns me just displayed rows. ie : if there are no filters, it retunrs only 15 rows, while my observablecollection count is about 1200 elements.

Can someone help me please.

public static IEnumerable Leaves(this IEnumerable<IGroup> groups)
        {
            foreach (IGroup group in groups)
            {
                foreach (object item in group.Leaves())
                {
                    yield return item;
                }
            }
        }

        public static IEnumerable Leaves(this IGroup group)
        {
            if (group == null)
            {
                return Enumerable.Empty<object>();
            }

            if (!group.HasSubgroups)
            {
                return group.Items;
            }

            return group.Subgroups.Leaves();
        }

        public static IEnumerable FlatItems(this GridViewDataControl grid)
        {
            if (grid.IsGrouping)
            {
                return grid.Items.Cast<IGroup>().Leaves();
            }

            return grid.Items;
        }

ps : I use this code as an extension class. 

Thanks.

Hi,

Any solution for this problem?

Hi Radouan,

You can transform your sourceCollection to an IQueryable, and then use our Where method (located in Telerik.Windows.Data.QueryableExtensions) extension method passing the grid's FilterDescriptors as the parameter.
