>>Is there anyway to give the mainwindows window size to the width and height of doubleanimation tag?
Once the UC has been loaded you can get a reference to its Window using the Window.GetWindow method:
public UserControl5()
{
InitializeComponent();
this.Loaded += (s, e) => { Window parentWindow = Window.GetWindow(this); };
}
...and then create the animation programmatically. Or you could bind to the Width of the window in the XAML markup:
<DoubleAnimation Storyboard.TargetProperty="Width" From="0" To="{Binding Width, RelativeSource={RelativeSource AncestorType=Window}}" Duration="0:0:2" />
This works in EventTriggers.
But if you set the Opacity of the UC to 0 in the XAML markup you could just apply a TranslateTransform to the UC and then animate the X property of it from -ActualWidth to 0:
public partial class UserControl5 : UserControl
{
public UserControl5()
{
InitializeComponent();
this.Loaded += UserControl5_Loaded;
}
void UserControl5_Loaded(object sender, RoutedEventArgs e)
{
TranslateTransform tt = new TranslateTransform(-this.ActualWidth, 0);
this.RenderTransform = tt;
this.Opacity = 1;
Window parentWindow = Window.GetWindow(this);
DoubleAnimation animation = new DoubleAnimation();
animation.From = -this.ActualWidth;
animation.To = 0;
Storyboard.SetTarget(animation, this);
Storyboard.SetTargetProperty(animation, new PropertyPath("(UserControl.RenderTransform).(TranslateTransform.X)"));
animation.Duration = TimeSpan.FromSeconds(1);
Storyboard sb = new Storyboard();
sb.Children.Add(animation);
sb.Begin();
}
}
<UserControl x:Class="WpfApplication9.UserControl5"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

d:DesignHeight="300" d:DesignWidth="300" Opacity="1" Background="Green">
<Grid>
<TextBlock Text="UC" FontSize="20"/>
</Grid>
</UserControl>
This will create a sliding effect.
Hope that helps.
