    <hr> <p>Assuming you are talking about WPF, then the positioning animation and easing functions would probably be best handled with xaml storyboard animation.</p> <p>The bigger question would be getting control of the applicaton or controls from another process. Assuming you have code for both applications it would be easier to implement some sort of interprocess communication and let the owning process reposition it's own elements. NamedPipeServerStream and NamedPipeClientStream would let you send/receive a reposition request.</p> <p>Otherwise, you might want to look into UI automation through AutomationPeers.</p> <p><a href="http://msdn.microsoft.com/en-us/library/ms747327(v=VS.85).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ms747327(v=VS.85).aspx</a></p> <hr> <p>Give the following xaml in an application:</p> <pre><code>&lt;Grid&gt; &lt;Button Name="btnOne" Content="this is test button"&gt; &lt;Button.Style&gt; &lt;Style TargetType="Button"&gt; &lt;Setter Property="Margin" Value="20" /&gt; &lt;Style.Triggers&gt; &lt;DataTrigger Binding="{Binding ElementName=PositionCheck,Path=IsChecked}" Value="True" &gt; &lt;Setter Property="Margin" Value="-150,20,150,20" /&gt; &lt;/DataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/Button.Style&gt; &lt;/Button&gt; &lt;CheckBox Content="CheckBox" Name="PositionCheck" Visibility="Collapsed" AutomationProperties.AutomationId="chkToggle" VerticalAlignment="Top" /&gt; &lt;/Grid&gt; </code></pre> <p>You can make the button jump around from another application like this:</p> <pre><code> Process p = Process.GetProcessesByName("ProjectWithButton").FirstOrDefault(); if (p != null) { AutomationElement ele = AutomationElement.RootElement.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ProcessIdProperty, p.Id)); if (ele != null) { AutomationElement chk= ele.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.AutomationIdProperty, "chkToggle")); TogglePattern toggle = chk.GetCurrentPattern(TogglePattern.Pattern) as TogglePattern; System.Diagnostics.Debug.WriteLine(toggle.Current.ToggleState); toggle.Toggle(); } } </code></pre> <hr> <p>You could just as easily trigger animations, or have two text boxes with coordinates for movement.</p>

    1. COBut wouldn't implementing such a function require some sort of interop wrapper? I was going to implement it with the following user32 function, but I wouldn't know if performance would be an issue: http://pinvoke.net/default.aspx/user32.MoveWindow

    2. COOnly top level WPF controls have window handles. You will not be able to control child controls with MoveWindow.

    3. COWell, it is not a button that I'd like to animate. Thank you for your previous write-up. I'm developing a WPF app that will animate the position of all of the running processes with windows. I'm attempting to ascertain the potential for animating all running windows with Sine easing.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
