Silverlight DataGrid行颜色绑定

问题描述

我想找到一种将DataGrid行的背景颜色绑定到绑定对象的属性的方法。

I'd like to find a way to bind the background color of rows of a DataGrid to a property of my bound objects.

这是我的XAML： / p>

Here is my XAML :

<sdk:DataGrid ItemsSource="{Binding MyItems}" />

我正在使用带有Silverlight 4的MVVM Light Toolkit。

推荐答案

您可以通过更改行模板来实现：

You can do it by changing a row template:

<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>

或者，您可以将每列标记为TemplateColumn，并在每个列中显式设置背景颜色：

Or you can mark each column as TemplateColumn and set background color explicitly in each of them:

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

以下是 DataGridRow 类：

<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="local:DataGridRow"
             xmlns:localprimitives="clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls.Data"
             xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
             xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows">
            <localprimitives:DataGridFrozenGrid Name="Root">
                <vsm:VisualStateManager.VisualStateGroups>

                    <vsm:VisualState x:Name="NormalAlternatingRow">

            </localprimitives:DataGridFrozenGrid>
        </ControlTemplate>
    </Setter.Value>
</Setter>

不要忘记更改绑定ColorPropertyOfItem 到您的模型中 Brush 类型的不动产。

And don't forget to change Binding ColorPropertyOfItem to a real property of the type Brush in your model.
