    copied!<p>If you run this code and click on tab 2 and then back on tab 1 the application goes insane and starts bouncing the column widths back and forth. Any suggestions on how to fix this?</p> <pre><code>&lt;Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"&gt; &lt;Grid IsSharedSizeScope="True"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="Auto" /&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;ColumnDefinition Width="Auto" SharedSizeGroup="Col3" /&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;TextBlock Text="Label 1" Grid.Row="0" Grid.Column="0" /&gt; &lt;TextBox Grid.Column="1" Grid.Row="0" Text="TextBox 1" /&gt; &lt;TextBlock Text="Label 2" Grid.Row="0" Grid.Column="2" /&gt; &lt;TextBox Grid.Column="3" Grid.Row="0" Text="TextBox 2" /&gt; &lt;DockPanel Grid.Row="1" Grid.Column="2" Grid.ColumnSpan="2"&gt; &lt;TabControl&gt; &lt;TabItem Header="Tab 1"&gt; &lt;Grid&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition SharedSizeGroup="Col3" /&gt; &lt;ColumnDefinition Width="Auto" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;TextBlock Text="Tab 1: Short Text.." Grid.Row="0" Grid.Column="0" /&gt; &lt;/Grid&gt; &lt;/TabItem&gt; &lt;TabItem Header="Tab 2"&gt; &lt;Grid&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition SharedSizeGroup="Col3" /&gt; &lt;ColumnDefinition Width="Auto" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;TextBlock Text="Tab 2: Short Text.." Grid.Row="0" Grid.Column="0" /&gt; &lt;TextBlock Text="Tab 2: Long Text..................................... " Grid.Row="1" Grid.Column="0" /&gt; &lt;/Grid&gt; &lt;/TabItem&gt; &lt;/TabControl&gt; &lt;/DockPanel&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>This is stripped from a similar application and greatly simplified. The root of the problem is the SharedSizeGroup "Col3". In the actual application there are other items that share that column so I cannot remove SharedSizeGroup unless there is another way to accomplish the desired behavior.</p>
