  1. POWPF window stretching incorrectly/weird behavior
    text
    copied!<p>I've had a weird behavior in WPF for awhile now, and I haven't been able to trace down where the problem is. In a nutshell, when I resize the window from the bottom or right, everything works as expected. But if I happen to grab it from the top or left, it stretches the window bu not the window contents. I've tried playing around wirh <code>HorizontalContentAlignment</code>, <code>HorizontalAlignment</code>, <code>VerticalContentAlignment</code>, &amp; <code>VerticalAlignment</code> to no avail. Anybody have any ideas where the issue lies?</p> <p><strong>Resize from Left:</strong> <img src="https://i.stack.imgur.com/3gAb4.png" width="200"></p> <p><strong>Resize from Top:</strong> <img src="https://i.stack.imgur.com/1ZPnX.png" width="200"></p> <p><strong>Resize from Right/Bottom:</strong> <img src="https://i.stack.imgur.com/T5tf5.png" width="200"></p> <p>Here's the XAML I'm using, with the inner controls removed for brevity:</p> <p><strong>Window XAML settings:</strong></p> <pre><code>&lt;Window x:Class="Agent_Template.MainWindow" Width="{Binding Source={x:Static main:Properties.Settings.Default}, Path=Width, Mode=TwoWay}" FontFamily="{Binding Source={x:Static main:Properties.Settings.Default}, Path=currentFont, Mode=TwoWay}" FontSize="{Binding Source={x:Static main:Properties.Settings.Default}, Path=currentFontSize, Mode=TwoWay}" Foreground="{Binding Source={x:Static main:Properties.Settings.Default}, Path=foregroundColor, Mode=TwoWay}" LocationChanged="Window_LocationChanged" Tag="parentWindow" Top="{Binding Source={x:Static main:Properties.Settings.Default}, Path=Top, Mode=TwoWay}" Topmost="False"&gt; </code></pre> <p><strong>Container XAML Settings:</strong></p> <pre><code>&lt;DockPanel Name="rvraDockPanel" Background="{Binding ElementName=BackColorPicker, Path=CurrentColor}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"&gt; &lt;Menu Height="Auto" DockPanel.Dock="Top"&gt; &lt;Menu.ItemsPanel&gt; &lt;ItemsPanelTemplate&gt; &lt;DockPanel HorizontalAlignment="Stretch" /&gt; &lt;/ItemsPanelTemplate&gt; &lt;/Menu.ItemsPanel&gt; &lt;WrapPanel Name="buttonDock" Grid.Column="0" HorizontalAlignment="Center" DockPanel.Dock="Bottom" Orientation="Horizontal"&gt; &lt;StatusBar Name="bottomStatusBar" Height="28" MinWidth="{Binding ElementName=buttonPanel, Path=ActualWidth}" Background="{Binding ElementName=clearButton, Path=Background}" BorderBrush="White" DockPanel.Dock="Bottom" Focusable="False" FontFamily="{Binding ElementName=fontSelector, Path=SelectedValue}" FontWeight="Bold" Foreground="Blue"&gt; &lt;Grid Width="{Binding ElementName=bottomStatusBar, Path=ActualWidth}" HorizontalAlignment="Center"&gt; &lt;TabControl Name="tabSelection" HorizontalContentAlignment="Center" Background="{Binding ElementName=BackColorPicker, Path=CurrentColor}"&gt; </code></pre> <p><strong>Update:</strong> LocationChanged code as requested</p> <pre><code> private void Window_LocationChanged(object sender, EventArgs e) { if (Properties.Settings.Default.windowSnap == true) { RealignChild(); } } /// &lt;summary&gt; /// Checks position of any SlideOut windows in relation to main /// program window and aligns child window next to main window. /// &lt;/summary&gt; private void RealignChild() { foreach (Window win in App.Current.Windows) { if (!win.IsFocused &amp;&amp; win.Tag.ToString() == "childWindow" &amp;&amp; win.Left &lt; this.Left) { win.Left = this.Left - win.Width; } if (!win.IsFocused &amp;&amp; win.Tag.ToString() == "childWindow" &amp;&amp; win.Left &gt; this.Left) { win.Left = this.Left + this.Width; } win.Top = this.Top; } } </code></pre> <p>Turns out this was the problem, as when I removed the XAML part of it the problem was corrected. I <em>do</em> want to keep this method though, as there's a method that depends upon it to keep <code>ChildWindows</code> of the <code>MainWindow</code> locked to the edge. I would like to continue using this if possible.</p>
