I'm using a WPF DataGrid and I put a DataGridTemplateColumn. Because the column should perform edit on a complex type (it's an object), I decided to put a togglebutton that open a popup. The code is the follow:
<DataTemplate>
<Grid>
<ToggleButton Grid.Column="2" x:Name="tb" Focusable="false" IsChecked="False" ClickMode="Press" Content="Edit values" />
<Popup IsOpen="{Binding ElementName=tb, Path=IsChecked, Mode=OneWay}" Placement="Bottom" x:Name="Popup" Focusable="False" StaysOpen="False" AllowsTransparency="True" Margin="0,1,0,0">
<Grid x:Name="dd" SnapsToDevicePixels="True">
<Border x:Name="ddb" Margin="0,-1,0,0" BorderBrush="DarkGray" BorderThickness="1" CornerRadius="0,0,3,3" Background="Gray">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="Uno:" Grid.Row="0" Grid.Column="0" />
<TextBox Text="{Binding Path=calendar.uno, Mode=TwoWay, StringFormat={}{0:0.##}}" Grid.Row="0" Grid.Column="1" />
<TextBlock Text="Due:" Grid.Row="1" Grid.Column="0" />
<TextBox Text="{Binding Path=calendar.due, Mode=TwoWay, StringFormat={}{0:0.##}}" Grid.Row="1" Grid.Column="1" />
<TextBlock Text="Tre:" Grid.Row="2" Grid.Column="0" />
<TextBox Text="{Binding Path=calendar.tre, Mode=TwoWay, StringFormat={}{0:0.##}}" Grid.Row="2" Grid.Column="1" />
</Grid>
</Border>
</Grid>
</Popup>
</Grid>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
The popup works, but often the following exception occurs:
System.ArgumentNullException was unhandled
Message=Value cannot be null.

What's the problem? (use multiple columns is not a valid alternative)
currently I have this exception in my app too; same stack trace. I found also few solutions for this but these solutions are not very "nice":
1 I used aero style for whole dialog where I have DataGrid to have same look for default controls in different Windows versions (mainly for XP to look controls "nicer"). When I comment following part of code in xaml of dialog no other exception is showing:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/PresentationFramework.Aero, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml" />
</ResourceDictionary.MergedDictionaries>
But I'm on XP now, I must check if this problem is solved also on Win7.
EDIT: works also for Windows7.
2 Try check this link on microsoft page: http://support.microsoft.com/kb/2498911
3 As it is written also on microsoft page you can still turn off Virtualization for Row or Column of your datagrid but if you have for example 1000 rows it takes some time to load everything :/
EDIT :
4. I downloaded the Aero.NormalColor.xaml (part of themes from microsoft available here: http://msdn.microsoft.com/en-us/library/aa970773.aspx) and add this theme to my app.xaml to app dictionary. It seems that this fixed the problem (probably same look but some differencies in code for this themes).
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Themes/GlassButton.xaml"/>
<ResourceDictionary Source="Themes/Aero.NormalColor.xaml"/>

I am following the example posted by Telerik on how to show/hide columns in their RadGridView control, as shown here:
<StackPanel x:Name="CustomizeGrid" Background="Transparent" Orientation="Horizontal">
<ListBox ItemsSource="{Binding Columns, ElementName=WorklistGridView}">
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding Header}" IsChecked="{Binding IsVisible, Mode=TwoWay}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<telerik:RadGridView x:Name="WorklistGridView" AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed" IsReadOnly="True" SelectionMode="Multiple"
CanUserSelect="False" IsSynchronizedWithCurrentItem="False" ItemsSource="{Binding Mode=OneWay}" IsFilteringAllowed="True">
<telerik:RadGridView.Columns>
<telerik:GridViewSelectColumn x:Name="Select" IsResizable="False" />
<telerik:GridViewDataColumn Header="Status" DataMemberBinding="{Binding OrderStatusDescription}"/>
<telerik:GridViewDataColumn Header="Patient Name" DataMemberBinding="{Binding PatientName}"/>
But the example is not compiling correctly. The problem is here: CheckBox `Content="{Binding Header}" The main error listed is: Value does not fall within the expected range.
I'm not sure why this is happening. I'll try to post the rest of the error below. Does anyone else have this working, or have any ideas what's up?

I managed to replicate your issue but I receive different exception ("Element is already the child of another element"). I think the reason can be the same so see if it helps.
A little debugging shows that when SelectionMode is set to Multiple then the Header of GridViewSelectColumn becomes a CheckBox. This means that you're trying to add same CheckBox to both column header and CheckBox content inside your ListBox. Just try to remove SelectionMode and see if you have the same issue or not.
If that's the case then you can fix issue by adding a converter to CheckBox.Content binding that passes through only strings. For example:
public class HeaderConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (value is string)
return value;
return string.Empty;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
Then in XAML:
<ListBox ItemsSource="{Binding Columns, ElementName=WorklistGridView}">
<ListBox.Resources>
<local:HeaderConverter x:Key="headerConverter" />
</ListBox.Resources>
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding Header, Converter={StaticResource headerConverter}}"
IsChecked="{Binding IsVisible, Mode=TwoWay}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I'm playing around with the glass border in WPF and I've found a problem.
When I extend the glass border of a window, the drag and drop functions won't work anymore... for example dragging a GridSplitter around ends with an exception.

What can I do to solve this problem?
Have you tried adding an AdronerDecorator at the root of your window? I was getting the same exception, but in my case my WPF control was hosted within an HwndSource in an MFC window. See this MS knowledgebase article for more information.
I have a problem with the ListPicker component. I download a sample from: http://code.msdn.microsoft.com/Windows-Phone-71-Local-da2fdf80. It is compile, but when I'd like to change page (contains ListPicker), exception was thrown.

I am following the example posted by Telerik on how to show/hide columns in their RadGridView control, as shown here:
<StackPanel x:Name="CustomizeGrid" Background="Transparent" Orientation="Horizontal">
<ListBox ItemsSource="{Binding Columns, ElementName=WorklistGridView}">
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding Header}" IsChecked="{Binding IsVisible, Mode=TwoWay}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<telerik:RadGridView x:Name="WorklistGridView" AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed" IsReadOnly="True" SelectionMode="Multiple"
CanUserSelect="False" IsSynchronizedWithCurrentItem="False" ItemsSource="{Binding Mode=OneWay}" IsFilteringAllowed="True">
<telerik:RadGridView.Columns>
<telerik:GridViewSelectColumn x:Name="Select" IsResizable="False" />
<telerik:GridViewDataColumn Header="Status" DataMemberBinding="{Binding OrderStatusDescription}"/>
<telerik:GridViewDataColumn Header="Patient Name" DataMemberBinding="{Binding PatientName}"/>
But the example is not compiling correctly. The problem is here:
CheckBox Content="{Binding Header}"
The main error listed is: Value does not fall within the expected range.
I'm not sure why this is happening. I'll try to post the rest of the error below. Does anyone else have this working, or have any ideas what's up?

So I've got an observable collection bound into an ItemsControl.
When I add items to the collection I get an exception of index out of range from the Visual collection.
<ItemsControl x:Name="ReportPages" ItemsSource="{Binding History}" DockPanel.Dock="Top">
<ItemsControl.Template>
<ControlTemplate TargetType="ItemsControl">
<ItemsPresenter HorizontalAlignment="Center"/>
</ControlTemplate>
</ItemsControl.Template>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding ChildWindows}">
<ItemsControl.Template>
<ControlTemplate TargetType="ItemsControl">
<Grid Margin="0,10,0,10" >
<ItemsPresenter />
<Border x:Name="ResizeFrame" BorderThickness="4" BorderBrush="LightBlue" Visibility="{Binding Active, Converter={StaticResource BooleanToVisibilityConverter}}"/>
</Grid>
</ControlTemplate>
</ItemsControl.Template>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas x:Name="LayoutCanvas" Background="white" ClipToBounds="true"
MouseDown="History_MouseLeftButtonDown" PreviewMouseDown="ClosePanels"
Width="{Binding PageSizeProp.PageWidth}" Height="{Binding PageSizeProp.PageHeight}"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The inner ChildWindows is the collection I'm adding items to. One think of note is that ChildWindows is a ReadOnlyObservableCollection, I'm adding via a method that has access to the Collection it is based on.
I'm at a total loss for why this is happening (and only some times).

I had the same problem and my understanding of it
(credits to https://stackoverflow.com/users/249723/vivien-ruiz for the link)
is simply that you are "bound" to have problems if you modify an ObservableCollection which takes part in an ItemSource binding. I found that inserting at index 0 "solves" my problem, but it could still crash. It shouldn't be modified because it isn't a thread-safe class. A better solution is to act on a copy of the list and assign the copy to the bounded collecion once the operation is completed.
For example:
ObservableCollection<ListViewItem> newList = new ObservableCollection<ListViewItem>(mCurrentList);
...
ListViewItem item = new ListViewItem();
item.Content = image;
newList.Add(item);
...
mPictures = newList;
I had a similar problem, took me months to find out the cause, but found it ^^
Check this site, especially if you modify the list from another thread. You seem to have a race condition, may be this is the same one !
