I have a TreeViewItem . I'd like to get parent node of this item if any. However TreeViewItem.ParentTreeViewItem property is internal, and thus not accessible. There is no reason to hide this property from developers, however, someone very smart decided that way. How do I proceed? Is there any workarounds (reflection on private members is not working in SL)? Found an ugly, but working way: static TreeViewItem GetParentItem(TreeViewItem item) { for (var i = VisualTreeHelper.GetParent(item); i != null; i = VisualTreeHelper.GetParent(i)) if (i is TreeViewItem) return (TreeViewItem)i; return null;

I would like to implement a custom zoom slider for a Bing Maps control in my silverlight application. I can set up the mechanics of it in a pretty straightforward way: <Slider ... Value="{Binding ZoomLevel, Mode=TwoWay, ElementName=MyMap}"/> However, I can't find a way to bind the Maximum and Minimum properties of the Slider to the maximum and minimum available zoomlevel for the map. I am using the default views (Road, Aerial) and no custom tilesets or anything fancy. I've tried something like this: Maximum="{Binding Path=Map.Mode.ZoomRange.To, Mode=TwoWay}" Minimum="{Binding Path=Map.Mode

I have a datagrid with master detail implementation as follows: <data:DataGrid x:Name="dgData" Width="600" ItemsSource="{Binding Path=ItemCollection}" HorizontalScrollBarVisibility="Hidden" CanUserSortColumns="False" RowDetailsVisibilityChanged="dgData_RowDetailsVisibilityChanged"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Item" Width="*" Binding="{Binding Item,Mode=TwoWay}"/> <data:DataGridTextColumn Header="Company" Width="*" Binding="{Binding Company,Mode=TwoWay}"/> </data:DataGrid.Columns> <data:DataGrid.RowDetailsTemplate> <DataTemplate> <data:DataGrid x:Name="dgrdRowDetail

I am trying to implement reordering rows in a Silverlight DataGrid. For this I am extending the default DataGridDragDropTarget , and I need to override and implement the following method: protected override DataGridRow ContainerFromIndex(DataGrid itemsControl, int index) { } How can I get the DataGridRow from the DataGrid and the Index? A slight improvement on Herzmeister's answer, see comments: protected override DataGridRow ContainerFromIndex(DataGrid itemsControl, int index) { var rowsPresenter = itemsControl.GetVisualDescendants().OfType<DataGridRowsPresenter>().FirstOrDefault(); if

I have a behavior that exposes several command properties. Typically I use MVVM Light and would just use a routed command in my view model and bind to those. However, this project is using Caliburn.Micro so I'm trying to do it the Caliburn.Micro way. Is there some syntax I can use on the Message.Attach to do this (is there any good documentation on the parser for Message.Attach)? Do I have to modify the behavior to expose events to make this work with Caliburn.Micro? Caliburn.Micro has its own mechanism for view/viewmodel communication as an alternative to commanding called Actions . You

I have a feeling i'm missing something obvious here, but i can not find a way to iterate through a DataGrids DataGridRow collection. I have a grid which has an itemssource of a collection of my class set. I am trying to iterate through the rows and highlight any rows that meet a certain condition but can't for the life of me see how. You don't want to iterate through the grid. That's old-skool WinForms thinking. The Grids in WPF and Silverlight have been redesigned with MVVM in mind; with separation of concerns. Instead of manipulating the grid, you work directly with your objects that are
