Travis, you’ll need to change ColumnWidth to RowHeight in the .xaml file too.

Using Lucas’ code, i get an error saying: “Unhandled Error in Silverlight Application Cannot resolve TargetProperty RowHeight on specified object. at MS.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData)\n at MS.Internal.XcpImports.MethodEx(DependencyObject obj, String name)\n at System.Windows.Media.Animation.Storyboard.Begin()\n at VideoWebsitePractice.MainPage.HideToolbar_Click(Object sender, RoutedEventArgs e)\n at System.Windows.Controls.Primitives.ButtonBase.OnClick()\n at System.Windows.Controls.Button.OnClick()\n at System.Windows.Controls.Primitives.ButtonBase.OnMouseLeftButtonUp(MouseButtonEventArgs e)\n at System.Windows.Controls.Control.OnMouseLeftButtonUp(Control ctrl, EventArgs e)\n at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)”);

Instead of using Column Width, i am using row height because i want an animated row. Anyone know what the issue could possibly be?

Great post. Quick solution. I code in c# and went through the process of converting it. In case anyone else out there needs this bit of code…here it is.

private static readonly DependencyProperty ColumnWidthProperty = DependencyProperty.Register(“ColumnWidth”, typeof(double), typeof(MainPage),
new PropertyMetadata(ColumnWidthChanged));
private double ColumnWidth {
get { return (double)GetValue(ColumnWidthProperty); }
set { SetValue(ColumnWidthProperty, value); }
}

private static void ColumnWidthChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) {
((MainPage)d).sideBarWidth.Width = new GridLength((double)e.NewValue);
}

Easier solution using ObjectAnimationUsingKeyFrames : No real smoothing, but 2-3 intermediate key frames will help. Kostya

Please can everyone you help me.

Hey, i ran into your blog while searching for this solution. I implemented my own later on which is less powerful (no gridsplitter) but it’s xaml only so i thought i’d share it.
