更改Silverlight Datagrid中的行顏色

Question

我想更改行中的顏色。所以基本上。我從我的Web服務中獲得了所有管理員的姓名。我想將該列表與我的datagridsource中的信息進行比較。如果他們是管理員，我希望他們的行變成紅色。

void proxy_GetListOfAdminsInGroupCompleted(object sender, gkws.GetListOfAdminsInGroupCompletedEventArgs e) 
    { 

     TestlistBox1.ItemsSource = e.Result; 

     int i = 0; 
     foreach (var item in UsersInSelectedGroup[0]) 
     { 
      foreach (var admin in e.Result) 
      { 
       if (admin.ToString().Equals(item.ToString())) 
       { 

        //Code to change the color of the row where "admin.ToString().Equals(item.ToString())" 

       } 
      } 
      i++; 
     } 
    } 

謝謝！

Answer 1

我創建了一個示例CustomClass：

public class CustomClass 
    { 
     public string PropertyToBeWatched { get; set; } 
    } 

創建一個列表：

MyList = new ObservableCollection<CustomClass>(); 
      MyList.Add(new CustomClass() { PropertyToBeWatched = "1"}); 
      MyList.Add(new CustomClass() { PropertyToBeWatched = "2" }); 
      MyList.Add(new CustomClass() { PropertyToBeWatched = "2" }); 
      MyList.Add(new CustomClass() { PropertyToBeWatched = "2" }); 

然後創建Datagrid的：

<sdk:DataGrid ItemsSource="{Binding MyList}" RowStyle="{StaticResource Style1}"> 
      <sdk:DataGrid.Columns> 
       <sdk:DataGridTextColumn Binding="{Binding PropertyToBeWatched}" Header="Property1"/> 
      </sdk:DataGrid.Columns> 
     </sdk:DataGrid> 

然後資源：

      xmlns:sdk="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"

      <Setter Property="IsTabStop" Value="False"/>

        <ControlTemplate TargetType="sdk:DataGridRow">

           <Rectangle x:Name="BackgroundRectangle" Grid.ColumnSpan="2" Fill="Red" Opacity="0" Grid.RowSpan="2"/> 
           <Rectangle x:Name="InvalidVisualElement" Grid.ColumnSpan="2" Fill="#FFF7D8DB" Opacity="0" Grid.RowSpan="2"/> 
           <sdk1:DataGridRowHeader x:Name="RowHeader" sdk1:DataGridFrozenGrid.IsFrozen="True" Grid.RowSpan="3"/> 
           <sdk1:DataGridCellsPresenter x:Name="CellsPresenter" Grid.Column="1" sdk1:DataGridFrozenGrid.IsFrozen="True"/> 
           <sdk1:DataGridDetailsPresenter x:Name="DetailsPresenter" Grid.Column="1" Grid.Row="1"/> 
           <Rectangle x:Name="BottomGridLine" Grid.Column="1" HorizontalAlignment="Stretch" Height="1" Grid.Row="2"/> 
          </sdk1:DataGridFrozenGrid> 
         </Grid> 
        </ControlTemplate> 
       </Setter.Value> 
      </Setter> 
     </Style> 

，這是轉換器：

public class RowStyleConverter : IValueConverter 
    { 
     public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
     { 
      if (((CustomClass)value).PropertyToBeWatched == "1") 
       return App.Current.Resources["Red"] as SolidColorBrush; 
      else 
       return App.Current.Resources["Green"] as SolidColorBrush; 
     } 

     public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 
     { 
      throw new System.NotImplementedException(); 
     } 
    } 

它基本上獲取和設置基礎上的財產「PropertyToBeWatched」的SolidColorBrush。

希望這會有所幫助
