copied!<p>Its a common requirement to convert a boolean to one of two instances of some arbitary type.</p> <p>Personally I think this is the best tool for the job: <a href="http://geekswithblogs.net/codingbloke/archive/2010/05/28/a-generic-boolean-value-converter.aspx" rel="nofollow">Generic Bool To Value Converter</a> (but there may be some bias in that opinion)</p> <p>Place an instance of the provided converter in your UserControl's resources:-</p> <pre><code> <UserControl.Resources> <local:BoolToBrushConverter x:Key="Highlighter" FalseValue="White" TrueValue="Yellow" /> </UserControl.Resources> </code></pre> <p>Now you can apply this converter to a binding the ties a boolean value from the ViewModel to a property of type <code>Brush</code>.</p> <p>However you have a bigger problem, how do you apply this converter to an individual data row? The <code>DataGrid</code> does not directly allow you set a binding that is set on each row.</p> <p>Assuming you're not a "no code in the view", you can do this with another static resource to hold a simple <code>Binding</code> then use the data grids <code>LoadingRow</code> event to apply it to each row that gets loaded.</p> <pre><code> <UserControl.Resources> <local:BoolToBrushConverter x:Key="Highlighter" FalseValue="White" TrueValue="Yellow" /> <Binding x:Key="RowBackgroundBinding" Path="yourBoolProperty" Converter="{StaticResource Highlighter}" /> </UserControl.Resources> </code></pre> <p>On the DataGrid:-</p> <pre><code> <DataGrid x:Name="dg" LoadingRow="dg_LoadingRow" ...> </code></pre> <p>Then in code-behind:-</p> <pre><code> private void dg_LoadingRow(object sender, DataGridRowEventArgs e) { e.Row.SetBinding(DataGridRow.BackgroundProperty, (Binding)Resources["RowBackgroundBinding"]); } </code></pre> <p>This will set up the binding on each row as it loads.</p>
