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}">

In WPF, I'm trying to move an image from left to center, pause for a second, then move the image to the right.
I'm trying to achieve it using ObjectAnimationUsingKeyFrames.
<BeginStoryboard>
<Storyboard Storyboard.TargetName="RoundNumberText" >
<ObjectAnimationUsingKeyFrames Duration="0:0:1" Storyboard.TargetProperty="Left">
<DiscreteObjectKeyFrame Value="400" KeyTime="0:0:0.5"/>
<DiscreteObjectKeyFrame Value="1400" KeyTime="0:0:1.5"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
Somehow i got the error message on the TargetProperty that the object does not supported by this properties. I've tried with margin as well, but still giving error.
Appreciate if anyone could help.
To set the value for alignment, you need to do something like this:
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="MyImage"
Storyboard.TargetProperty="HorizontalAlignment">
<DiscreteObjectKeyFrame KeyTime="0:0:0">
<DiscreteObjectKeyFrame.Value>
<HorizontalAlignment>Center</HorizontalAlignment>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
Below is my example, where the image appears in the role of the Label:
<Grid>
<Grid.Triggers>
<EventTrigger SourceName="MoveToCenter" RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="Test"
Storyboard.TargetProperty="HorizontalAlignment">
<DiscreteObjectKeyFrame KeyTime="0:0:0">
<DiscreteObjectKeyFrame.Value>
<HorizontalAlignment>Center</HorizontalAlignment>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames BeginTime="0:0:1"
Storyboard.TargetName="Test"
Storyboard.TargetProperty="HorizontalAlignment">
<DiscreteObjectKeyFrame KeyTime="0:0:0">
<DiscreteObjectKeyFrame.Value>
<HorizontalAlignment>Right</HorizontalAlignment>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Grid.Triggers>
<Label x:Name="Test" Content="Test" Width="300" Height="200" Background="Aqua" HorizontalAlignment="Left" />
<Button Name="MoveToCenter" Content="MoveToCenter" Width="120" Height="30" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Grid>
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.
I have a Grid, which is displaying this odd behavior:
Everytime I have horizontal scrollbars available, and I use it, the headers get disaligned with the cells of the rows.
My grid is styled this way:
<Style TargetType="sdk:DataGridRow">
<Setter Property="IsTabStop" Value="True" />
<Setter Property="Template">

For a while, if I take the customization off of the grid (the codeblock above) from my application it works, however, I loose some visual styles, which I don't want to.
I particularly don't understand WHAT in my stylization could make it happen, for I don't fully understand it. Would someone know?
Thanks in advance.

My problem was solved by putting the template code inside the grid definition, not outside, like I was doing.
Highlight entire rows only in Silverlight DataGrid
I've got a "toolbar" type control that is basically a set of buttons for "groups" of other buttons. The buttons and groups are arranged horizontally along the top of my window.
What I'd like is to have, when the user clicks one of the buttons for one of the groups, the list (probably an ItemsPanel) of other buttons for that group expands from being 0 width to being however wide it needs to be to hold the list of buttons.
So you'd start off with something like this:
_______
|G|G|G|
-------
where G is a group button. And if you click on the middle group button, you'll end up with this:
_______________
|G|G|B|B|B|B|G|
---------------
where the original group buttons are still there and the new buttons for the selected group have "grown" into place.
What's the best way to make this happen? Should I use a ListBox as the outer container and trigger an animation when IsSelected changes on one of the ListBoxItems? If so, how do I write an animation that goes from 0 width (or hidden) to "full width" (whatever that may be)?
Thanks!
I'd use fluid layout, not that this is the best way or anything, but its one way. Basically allows you to animate between say Auto width and 0 width.

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:

<Setter Property="IsTabStop" Value="True" />
<Setter Property="Template">
