I have a ListView which occupies to cells of Grid:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<ListView
x:Name="itemListView"
Grid.Column="0"
Grid.ColumnSpan="2"
/>
</Grid>
I wanted to change colspan in Storyboard:
<VisualState x:Name="Snapped">
<Storyboard>
<ObjectAnimationUsingKeyFrames
Storyboard.TargetName="itemListView"
Storyboard.TargetProperty="Grid.ColumnSpan">
<DiscreteObjectKeyFrame KeyTime="0" Value="1" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
But it ended up in runtime error...
The solution is pretty simple, but not obvious (well, at least not for me):
<ObjectAnimationUsingKeyFrames
Storyboard.TargetName="itemListView"
Storyboard.TargetProperty="(Grid.ColumnSpan)">
<DiscreteObjectKeyFrame KeyTime="0" Value="1" />
</ObjectAnimationUsingKeyFrames>
It showed up that this kind of property should be enclosed in parentheses.

does anyone know how to get the visual state manager running in the following code? Even Blend is not helping at all. If I define Visual State Groups and Visual States nothing works or changes.

I'm trying to decrease the font of the CheckBox through a style in Expression Blend. No matter what value I set for the text, it always shows up the same. For now, I have made the text purposely small to make sure I notice when it changes, but the text stays the same size. The text size doesn't change in Expression Blend, Visual Studio, or the emulator. I'm not sure why it's not working. The XAML is below:
<Style x:Key="CheckBoxStyle1" BasedOn="{StaticResource PhoneRadioButtonCheckBoxBase}" TargetType="CheckBox">

Edit: I can't even change the font size when setting it in the CheckBox declaration, but I can change the FontWeight.
Rather than overriding the style, override the "Generated Content" (under Edit Additional Templates menu). This results in a blank style that you can put anything you like in. For example:
In resources:
<DataTemplate x:Key="DataTemplate1">
<Grid>
<TextBlock Text="CheckBox" FontSize="19.333"/>
</Grid>
</DataTemplate>
In page content:
<CheckBox HorizontalAlignment="Right" ContentTemplate="{StaticResource DataTemplate1}"/>
I'm not sure whether this will work with FontSize but I used the following to style the CheckBox text foreground to PhoneAccentBrush.
<CheckBox IsChecked="{Binding IsChecked}">
<CheckBox.Content>
<TextBlock Text="Some Text"
Style="{StaticResource PhoneTextNormalStyle}"
Foreground="{StaticResource PhoneAccentBrush}" />
</CheckBox.Content>
</CheckBox>
I'm using silverlight 4 datagrid. I have datagridtextcolumn and also datagrid template column, for them i'm specifying the column with in '*', 'sizetoheader'.
Everything works fine if i have some 20 records in my datagrid, however if my grid have more than 30 records, it's behaving odd. It's like column headers and their columns are not properly aligned, due to this improper alignment, horizontal appears unnecessarily, if i click any of the column header, then everything will be ok. The alignment of column header is exactly with the columns.
This is also happening to me.
In my case, by the moment I set a template to my rows, like this:
<Style TargetType="sdk:DataGridRow">
<Setter Property="IsTabStop" Value="True" />

I get an odd behavior, which is everytime I have horizontal scrollbars available, and I use it, the headers get disaligned with the cells of the rows.
For a while, It is working for me if I take the customization of the grid (the codeblock above) from my application, however, I loose some visual styles, which I don't want. If you have it, and do not need it so much, you could try removing it too.

I have a main datagrid, then an accordion control below it. In one of the accordion items I have another datagrid that binds to the selected item of the first datagrid. Simple xaml is:
<sdk:DataGrid Name="dgMain" ItemsSource="{Binding SomeSource}" />
<toolkit:Accordion>
<toolkit:AccordionItem Header="Details">
<sdk:DataGrid ItemsSource="{Binding ElementName=dgMain, Path=SelectedItem.Children}"/>
</toolkit:AccordionItem>
</toolkit:Accordion>
I have VerticalAlignment property of the second grid set to "Stretch" so it stretches as different collection sizes are bound to it, but the problem is it only stretches within the AccordionItem size so if I select a new item in the first grid that has more "Children" then I have to scroll the second grid because the AccordionItem didn't change.
AccordionItem region will only change when i condense and expand it again. Setting VerticalContentAlignment to "Stretch" for the accordion item does not work. I guess because it only triggers this when first expanded.
Does anyone know what else I could try or if I'm missing something. I'd prefer to stick with xaml solution so I can stay MVVM-friendly, but glad to hear everything.
The reason that the AccordionItem doesn't resize properly is because there is a bug in one of its control Parts - ExpandableContentControl. The issue is described here.
I think you can either fix its source code or, more easily, replace this control from its default style with a normal ContentControl. I have included a style here with a normal ContentControl and tested it in the code that #JohnNicholas provided, and it works.

PS. If you want to animate the expanding/collapsing you can just define your own animation in the AccordionItem's Collapsed and Expanded visual states.
It is really a late reply and hope it can be of any help. :)
I had a similar issue long time ago, I think this is what I did. Basically in the size changed event of the inner datagrid, we reinvoke the measure pass of the accordion.
In the inner data grid, attach the size change event as so.
private void InnerDataGrid_SizeChanged(object sender, System.Windows.SizeChangedEventArgs e)
{
this.AccordionName.Measure(new Size());
this.AccordionName.UpdateLayout();
}
this code will demonstrate the problem
The accordion in the sub-sub-accordion will not expand when you first expand it. However if you collapse its parent and reaxpand it will show. Alternativley resize the browser window and it will also resize everythign to show it.
this example is a bit contrived but usually i am showing a sub control that also has an accordino to get this problem. There are also problems when you wrap everythign in a scrollviewer But these are probably related to the first.

I need to animate this property using a Storyboard.
Is writing your own animation is a best choice?
No, it is quite possible using the standard XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" x:Name="col0"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.Resources>
<Storyboard x:Key="sbCol0ToAuto">
<ObjectAnimationUsingKeyFrames
BeginTime="0" Duration="0"
Storyboard.TargetName="col0" Storyboard.TargetProperty="Width">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<GridLength>*</GridLength>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</Grid.Resources>
...
</Grid>
And even easier back to Auto:
<DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static GridLength.Auto}">
