  1. POHow do I set a binding property via a style in XAML?
    text
    copied!<p>I have a data template for a type that defines a bunch of data entry fields, all with similar settings on the textboxes, something like this:</p> <pre><code>&lt;DataTemplate x:Key="ContactInfo"&gt; &lt;DockPanel&gt; &lt;HeaderedContentControl Header="Contact Name"&gt; &lt;TextBox Width="200" Text="{Binding Name, ValidatesOnDataErrors=True}"/&gt; &lt;/HeaderedContentControl&gt; &lt;HeaderedContentControl Header="Contact Quest"&gt; &lt;TextBox Width="200" Text="{Binding Quest, ValidatesOnDataErrors=True}"/&gt; &lt;/HeaderedContentControl&gt; &lt;HeaderedContentControl Header="Contact Favorite Color"&gt; &lt;TextBox Width="200" Text="{Binding Color, ValidatesOnDataErrors=True}"/&gt; &lt;/HeaderedContentControl&gt; &lt;/DockPanel&gt; &lt;/DataTemplate&gt; </code></pre> <p>I would like to reduce duplication as much as possible and eliminate as many of the duplicated properties as I can. I know that I can get rid of the repeated Width attribute by adding</p> <pre><code>&lt;DataTemplate.Resources&gt; &lt;Style TargetType="x:Type TextBox"&gt; &lt;Setter Property="Width" Value="200"/&gt; &lt;/Style&gt; &lt;/DataTemplate.Resources&gt; </code></pre> <p>to the DataTemplate. However, I also want to get rid of the redundant "ValidatesOnDataErrors=True" setting.</p> <p>I have tried modifying the style to set it thusly:</p> <pre><code>&lt;DataTemplate.Resources&gt; &lt;Style TargetType="x:Type TextBox"&gt; &lt;Setter Property="Width" Value="200"/&gt; &lt;Setter Property="Text.Binding.ValidatesOnDataErrors" Value="True"/&gt; &lt;/Style&gt; &lt;/DataTemplate.Resources&gt; </code></pre> <p>but at compile time it complains about ValidatesOnDataErrors not being resolvable.</p> <p>How does one accomplish what I want? I have upwards of 50 fields to style, and I don't want to change all of them one by one if I decide to change my validation technique.</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
