DataGridコントロール

DataGridコントロール内の行ごとの背景を変更することができますが、下記のような「BackGround」プロパティによって、処理で反映できない。

(e.Row as DataGridRow).BackGround = new SolidColorBrush()

下記のようなスタイル定義の方法で、行背景を変更できます。

(e.Row as DataGridRow).Style = Application.Current.Resources["DataGridRowStyle"] as Style;

<Style x:Key="DataGridRowStyle" TargetType="sdk:DataGridRow">
   <Setter Property="Background" Value="#F0FF0000"/>
