Silverlight ligne de grille de données de couleur de liaison

Vous pouvez le faire en modifiant une ligne de modèle:

<sdk:DataGrid ItemsSource="{Binding MyItems}">
    <sdk:DataGrid.RowStyle>
        <Style TargetType="sdk:DataGridRow">
            <Setter Property="Template">
            ...
                <Rectangle x:Name="BackgroundRectangle" Fill="{Binding ColorPropertyOfItem}" />
            ...
            </Setter>
        </Style>
    </sdk:DataGrid.RowStyle>
</sdk:DataGrid>

Ou vous pouvez marquer chaque colonne TemplateColumn et de définir la couleur de fond explicitement dans chacun d'eux:

<sdk:DataGridTemplateColumn Header="ColumnName" SortMemberPath="ColumnProperty">
    <sdk:DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding ColumnProperty}" Background="{Binding ColorPropertyOfItem}" />
        </DataTemplate>
    </sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>

Ici est un modèle de la DataGridRow classe:

</ControlTemplate>
</Setter.Value>
</Setter>

Et n'oubliez pas de changer Binding ColorPropertyOfItem d'un bien immobilier de type Brush dans votre modèle.
