You're right, I don't think that you can just stick UIElements into ViewPort3D.
One option is to try to simulate your desired 3D animation with the regular 2D system. For example, check out this blog post by Tess Ferrandez which shows how to do a flip between 2 UI elements:
Silverlight/WPF FlipImage Animation[^]
If you are using these animations as transitions and don't need to have active UI elements during those transitions, you may be able to persist your UI elements to an image and have that applied to a 3D element which you can add to your ViewPort3D.

Hi.
I'm reading a XML file that has been stored in IsolatedStorage.
But this Exception was occurring Root element is missing.
I'm dead sure that there isn't any troubles in the XML file, So I don't the know the result of the Exception 
Could you guide me ?
Thank you.
This is my snippet code :
using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
{
.
.
.
string SettingFilePath = "CodeColorizer\\setting.xml";
using (IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream(SettingFilePath, FileMode.Create, isoStore))
{
isoStream.Position = 0;
XmlReader xmlReader;
xmlReader = XmlReader.Create(isoStream);
<code>xmlReader.MoveToContent();</code>
string value;
while (xmlReader.Read())
{
switch (xmlReader.NodeType)
{
case XmlNodeType.Element:
{
if (xmlReader.Name == "IsVB")
{
value = (string)xmlReader.ReadContentAs(Type.GetType("String"), null);

Is FileMode.Create really the mode you want to open the file in?

I have the following code
<Border Margin="3,4,0,0" Height="205" VerticalAlignment="Top" BorderBrush="Black"
BorderThickness="2" HorizontalAlignment="Left" Width="891" CornerRadius="8,8,8,8">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<StackPanel.Clip>
<RectangleGeometry Rect="0,0,891,205" RadiusX="8" RadiusY="8"></RectangleGeometry>
</StackPanel.Clip>
<Label Height="26" Name="label1" Width="205" HorizontalAlignment="Left" VerticalAlignment="Top"
HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontFamily="Arial" FontSize="14"
FontStyle="Italic" FontWeight="Bold" Content="Contacts" Background="Black" Foreground="LightSteelBlue"
ClipToBounds="True">
<Label.LayoutTransform>
<RotateTransform Angle="270" />
</Label.LayoutTransform>
</Label>
<telerik:RadGridView Name="gridviewContacts" AllowDrop="False" Height="203" VerticalAlignment="Top"
Margin="0,0,0,0" AutoGenerateColumns="False" FontFamily="Arial" ClipToBounds="False"
Width="863">
<telerik:Theming.Theme>
<telerik:VistaTheme />
</telerik:Theming.Theme>
</telerik:RadGridView>
</StackPanel>
</Border>
Essentially, I have a Border that contains a horizontally oriented StackPanel that contains a Label and a Telerik RadGridView. I want to put rounded corners on the Border element, and clip all of the other elements within the Border to not render outside the rounded corners.
The code above contains my latest non-working attempt. I tried to use the ClipToBounds property, but that doesn't seem to do anything.

I found this, Clipping of child elements[^].
<local:ClippingBorder Margin="3,4,0,0" Height="205" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="4" HorizontalAlignment="Left"

It tries to clip - just in a braindead way.
For example:
<Border Height="100" VerticalAlignment="Top" BorderBrush="Black"
BorderThickness="2" HorizontalAlignment="Left" Width="300" CornerRadius="20">
<StackPanel Orientation="Horizontal" Background="SteelBlue" >
<StackPanel.Clip>
<RectangleGeometry Rect="0,0,300,100" RadiusX="20" RadiusY="20" />
</StackPanel.Clip>
<Label Height="26" Name="label1" Width="100" HorizontalAlignment="Left" VerticalAlignment="Top"
HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontFamily="Arial" FontSize="14"
FontStyle="Italic" FontWeight="Bold" Content="Contacts" Background="Black" Foreground="LightSteelBlue" >
<Label.LayoutTransform>
<RotateTransform Angle="270" />
</Label.LayoutTransform>
</Label>
</StackPanel>
</Border>
Monkeying with the radius values, sometimes it does ok, sometimes it doesn't.
No bueno.

Hi,
I want to do some processing after knowing that a control has finished rendering. In windows forms we usually had events like OnRenderComplete with all the controls. But in WPF I found events like Loaded, Initialized, OnLayoutUpdated etc.. which do not inform you that the control has actually finished rendering on the UI.
Is there a way to identify this?

Next problem....
Here's some code
<DataTemplate x:Key="TestDataListTemplate">
<Border Margin="5" BorderThickness="1" BorderBrush="Black" CornerRadius="4">
<Grid Margin="5,2">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="{Binding Path=Usage}" Foreground="Black" FontWeight="Bold" FontFamily="Courier" FontSize="12"></TextBlock>
<TextBlock Grid.Row="1" FontFamily="Arial" Foreground="DarkBlue" Text="{Binding Path=Path, UpdateSourceTrigger=PropertyChanged}" FontSize="12"></TextBlock>
</Grid>
</Border>
</DataTemplate>
...which I use as a ListBoxItem.
If I want a context menu for each item like this, I manage to get the menu, editing the code to...
...<Grid Margin="5,2">
<Grid.ContextMenu>
<ContextMenu>
<MenuItem Header="Delete" />
</ContextMenu>
</Grid.ContextMenu>...
But how do I implement the click event???

Sorry....like this then...
<DataTemplate x:Key="TestDataListTemplate" >
...
<Grid Margin="5,2">
<Grid.ContextMenu>
<ContextMenu>
<MenuItem Header="Delete" Click="MenuItem_Click_DeleteProduct" />
</ContextMenu>
</Grid.ContextMenu>...
Error:ResourceDictionary root element requires a x:Class attribute...
If I add x:class="MyProgram.Window1" to <ResourceDictionary the i get this instead, among a few others...
Error: Partial declarations of MyProgram.Window1 must not specify different base classes....don't get it. 
Well, it seems like I have more problems. The goal is to have ListBox with DataTemplate items, then I want a ContextMenu where I can choose to delete an item... Maybe I have to think in another way.

Where is this DataTemplate resource located?
It looks like there's no problem with the template but there's a problem with where
the template an/or the click handler code is located...

I have created a separate file with my templates and style and use <ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="resourceDic.xaml"/>
</ResourceDictionary.MergedDictionaries>
|
|
|
|

You'll need an x:class set on your resource dictionary that references the
class containing the click handler.
For example:
<!-- Dictionary1.xaml -->
<ResourceDictionary
x:Class="WPFTester.DictionaryHandlerClass"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFTester">
<DataTemplate x:Key="TestDataListTemplate" DataType="{x:Type local:Item}">
<Border BorderBrush="SteelBlue" BorderThickness="4" >
<Grid Background="LightSteelBlue" Height="20" >
<Grid.ContextMenu>
<ContextMenu>
<MenuItem Header="Delete" Click="MenuItem_Click" />
</ContextMenu>
</Grid.ContextMenu>
</Grid>
</Border>
</DataTemplate>
</ResourceDictionary>
using System;
using System.Windows;
namespace WPFTester
{
public partial class DictionaryHandlerClass
{
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
}
}
}

Ok, thanks 
I tried that before but it doesn't seems like it's possible to use the startup Window1 class. Think I have to create a separate class behind my resource file and go from there...

Yes. ResourceDictionary is a different class than Window

I've recently decided to look into adding the ability to load WPF Windows to one of my pet projects. I also want to allow it to process speech, and other goodies. To achieve this, I've created a new class in my 'host' Windows Forms application, which inherits from System.Windows.Window. The requirements for a Window to be loaded are:
- It must have an attribute which contains the name, category, etc.
- It must inherit from my custom class
I have no problem with the first one, but the second one is where I fall down. I have added a reference to the 'host' application in the 'parasite' (sorry, don't know how else to describe it) application, and changed the C# back-end class to inherit from my custom class. When I try to build, I get this error
Partial declarations of 'SampleWPFMiniApp.wndMain' must not specify different base classes
I presume the designer is similar to that of Windows Forms in that the code is split between XAML and code. How would I specify the correct base class in XAML? For what it's worth, the base class I specified in my C# code is Host.ShellComponents.ParasiteWindow
|
|
|
|
|
There's no need to worry about my original post. By adding xmlns:src="clr-namespace:Host.ShellComponents.ParasiteWindow;assembly=Host" along with the other xmlns XAML, and then setting the root element to src:ParasiteWindow, I can compile successfully. But now I have another problem. How do I host a WPF Window (or equivalent) in a Windows Form? I've been trying to use the System.Windows.Interop.WindowInteropHelper class, and this shows the Window, but not as a child of the Windows Forms host

I have the following style:
<Style TargetType="{x:Type Image}" >
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType={x:Type Button},
AncestorLevel=1}, Path=IsEnabled}" Value="False">
<Setter Property="Opacity" Value="0.40" />
</DataTrigger>
</Style.Triggers>
</Style>
Where do I put it if I want it to be global to the application, and how do I get to it once it's there?
