    <p>I'm using a grid control from DevExpress. I've binded the grid to a DataView:</p> <pre><code>m_dvResponses = New DataView(...) m_dvResponses.Sort = "SEQUENCENUMBER" GridResponses.ItemsSource = m_dvResponses </code></pre> <p>Everything seems to work fine. When the underlying data changes, the grid updates automatically, so that's good.</p> <p>Problem is that I color some of the cells using a Converter on a specific column:</p> <pre><code>&lt;dxg:GridColumn FieldName="AGENCYNAME" CellStyle="{StaticResource AgencyCellStyle}"/&gt; &lt;Style x:Key="AgencyCellStyle" BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=CellStyle}}" TargetType="{x:Type dxg:CellContentPresenter}"&gt; &lt;Setter Property="BorderThickness" Value="8,0,0,0"/&gt; &lt;Setter Property="BorderBrush" Value="{Binding Path=RowData.Row, Converter={StaticResource AgencyBackgroundColorConverter}, ConverterParameter=AGENCY}" /&gt; &lt;Setter Property="Foreground" Value="{Binding Path=RowData.Row, Converter={StaticResource AgencyForegroundColorConverter}, ConverterParameter=AGENCY}" /&gt; &lt;/Style&gt; </code></pre> <p>When the data changes, the value is updated, but the converter doesn't seem to execute. The converter only executes when the grid paints itself.</p> <p><img src="https://i.stack.imgur.com/G2tQg.png" alt="Before ..."></p> <p><img src="https://i.stack.imgur.com/jdgPn.png" alt="After ..."></p> <p>Notice how the new "p1" didn't color itself since the Converter didn't fire on the update.</p> <p>My question is: Does a DataView trigger a converter when data gets updated? Are converters dependant on objects that implement the INotifyPropertyChanged interface?</p> <p>Thanks for your help!</p>

    1. COAs far as I know, converters are executed when a binding changes, and yes, I believe WPF's data binding is triggered via INotifyPropertyChanged or dependency properties. It's difficult to help you without seeing the specific code involved, though. I think if you edit your question to include some samples, you'll stand a better chance at getting an answer.

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.
