I'd like to use the new metro transitions (AddDeleteThemeTransition, ContentThemeTransition, ...), for my WPF 4 project. Can I use a dll ? Where could I download it ? WinRT/XAML is a different technology than WPF and none of its WinRT UI will work with WPF. Additionally these transitions seem to be using some different mechanism than regular Storyboards, so there is likely no way to just extract them to something that would work with WPF. Your only option would be to implement something yourself and make it look good. Or alternatively give up support for Windows 7 and implement your

As some of you have discovered, a new feature (?) appeared WPF 4, where the data binding engine may pass your custom control instances of the class MS.Internal.NamedObject with the name " {DisconnectedItem} " into the DataContext - instead of the data item your code is expecting (this happens when a templated control is disconnected by its ItemsControl). These are called sentinel objects. In existing code, this can lead to spurious exceptions where the code is unprepared for it. These can be swallowed up by the data binding subsystem, or they can wreak havoc. Keep an eye on your debug console.

I am using a DataGrid in row selection mode (i.e., SelectionUnit="FullRow" ). I simply want to remove the border that is being placed around the current cell when the user highlights a row in order to have true full row selection (and no cell level selection). I don't mind the notion of the grid maintaining the current cell, I just want to remove that pesky current cell border, perhaps by changing the style of the current cell. What is the easiest way to do this? You could set the BorderThickness for DataGridCell to 0 <DataGrid ... SelectionUnit="FullRow"> <DataGrid.CellStyle> <Style

I have a WPF DataGrid <DataGrid AutoGenerateColumns="False" Name="dataGrid1" IsReadOnly="True" > <DataGrid.Columns> <DataGridTextColumn Header="Site" Binding="{Binding Site}" Width="150" /> <DataGridTextColumn Header="Subject" Binding="{Binding Subject}" Width="310" /> </DataGrid.Columns> <DataGrid.ContextMenu> <ContextMenu> <MenuItem Header="Delete" Click="Context_Delete"> <MenuItem.Icon> <Image Width="12" Height="12" Source="Images/Delete.png" /> </MenuItem.Icon> </MenuItem> </ContextMenu> </DataGrid.ContextMenu> </DataGrid> I have the click event handler as: private void Context_Delete

Many times I have seen that the code in MeasureOverride and ArrangeOverride is same excepts calling measure and arrange in respective methods and a bit of additional logic like animation etc for each item in ArrangeOverride . Would it not be simple if you just have a method to pass your logic of measuring at one place and layout system remembers that and have an event when each item is about to add and you apply the additional logic of animation etc? Am I missing anything? slugster Yep, you are missing the subtle difference between the two. In MeasureOverride , the parent asks the child how

I want to copy all the datagrid records into datatable without using any loop. For Ex: Dim dt as New DataTable dt = Datagrid1.Items But this is not Working and giving an error message. My Development platform is Visual studio 2010 and language is WPF with vb.net 4.0 Rishap Gandhi This is the way to transfer all the records from DATAGRID to DATATABLE without using the LOOP. VB: Dim dt As New DataTable dt = CType(DataGrid1.ItemsSource, DataView).ToTable C#: DataTable dt = new DataTable(); dt = ((DataView)DataGrid1.ItemsSource).ToTable(); It depends how the datagrid is populated. If the
