Hi,

I have some custom sorting for RadTreeView (ASC and DESC)...but I need the indicating arrows to go with them in my TextBlock above that triggers the sorting...Is that possible ? Any help is appreciated.

Barry

 

<TextBlock Text="{x:Static properties:Resources.GroupHeader}" MouseUp="TextBlock_MouseUp" TextAlignment="Center" Style="{StaticResource HeaderTemplate}" HorizontalAlignment="Stretch"/>

 

        //GROUP CUSTOM SEARCH
        private void TextBlock_MouseUp(object sender, MouseButtonEventArgs e)
        {
            isoProvider.LoadFromStorage(groupTreeViewIsolatedStorage); //GET

            IEnumerable<GroupVM> groups = GroupTree.ItemsSource as IEnumerable<GroupVM>;

            if (GroupTreeViewOrdering.Content.Equals(ConstantsUnit.Key_SortAscending))
            {
                IEnumerable<GroupVM> test = groups.OrderByDescending(p => p.Name);
                GroupTree.ItemsSource = null;
                while (GroupTree.ItemsSource == null) {
                    GroupTree.ItemsSource = test;
                }

                //GroupTree.ItemsSource = groups.OrderByDescending(p => p.Name);
                GroupTreeViewOrdering.Content = ConstantsUnit.Key_SortDescending;
            }
            else if (GroupTreeViewOrdering.Content.Equals(ConstantsUnit.Key_SortDescending))
            {
                IEnumerable<GroupVM> test = groups.OrderBy(p => p.Name);
                GroupTree.ItemsSource = null;
                while (GroupTree.ItemsSource == null) {
                    GroupTree.ItemsSource = test;
                }

                //GroupTree.ItemsSource = groups.OrderBy(p => p.Name);
                GroupTreeViewOrdering.Content = ConstantsUnit.Key_SortAscending;
            }

            isoProvider.SaveToStorage(groupTreeViewIsolatedStorage); //SET
        }

Hi Barry,

If we have correctly understood your question you are trying to place sorting arrow next to the TextBlock when you are using RadTreeView control in the scenario describe in Implement Search, and Sort. If this is the case the RadTreeView doesn't support such functionality our of the box. Basically, you can use ToggleButton and place it next to the TextBlock and modified its appearance depending on the sorting (ACS or DESC). 

If we are in the wrong direction you can send us more information about the approach that you are trying to achieve in your application and sample project which could help us to better understand it.

yeah, I knew it was along-shot. The real solution it seems is to drop the textblock/RadTreeView and use RadTreeListView for "one stop shopping" for it all. Thanks for your reply !
