如果你想在View Model端擁有一個儲存格的顏色並綁定其屬性,您可以使用CellBinding功能輕鬆地做到這一點。
// Model(SampleDataItem.cs) public class SampleDataItem { public int ID { get; set; } public String Value1 { get; set; } public SolidColorBrush Value1Color { get; set;} // 要設定為Value1儲存格的背景色的顏色。 }
// Viewmodel(MainWindowViewModel.cs) public class MainWindowViewModel { private ObservableCollection _sampleData; public ObservableCollection SampleData { get { return _sampleData; } set { _sampleData = value; } } public MainWindowViewModel() { // 如果ID=1,Value1儲存格的背景色是粉紅色,如果ID=4,Value1儲存格的背景色是LightGreen,如果是其他情況,儲存格背景色會是透明的。 _sampleData = new ObservableCollection(); _sampleData.Add(new SampleDataItem() { ID = 1, Value1 = "aaa", Value1Color = new SolidColorBrush(Colors.Pink) }); _sampleData.Add(new SampleDataItem() { ID = 2, Value1 = "bbb", Value1Color = new SolidColorBrush(Colors.Transparent) }); _sampleData.Add(new SampleDataItem() { ID = 3, Value1 = "ccc", Value1Color = new SolidColorBrush(Colors.Transparent) }); _sampleData.Add(new SampleDataItem() { ID = 4, Value1 = "ddd", Value1Color = new SolidColorBrush(Colors.LightGreen) }); _sampleData.Add(new SampleDataItem() { ID = 5, Value1 = "eee", Value1Color = new SolidColorBrush(Colors.Transparent) }); } }
<!-- Model(MainWindow.xaml) --> <igDP:XamDataGrid ... DataSource="{Binding SampleData}" ...> <igDP:XamDataGrid.FieldLayoutSettings> <igDP:FieldLayoutSettings AutoGenerateFields="False" /> </igDP:XamDataGrid.FieldLayoutSettings> <igDP:XamDataGrid.FieldLayouts> <igDP:FieldLayout> <igDP:FieldLayout.Fields> <igDP:Field Name="ID" Label="ID"/> <igDP:Field Name="Value1" Label="Value1"> <!-- 用CellBinding將儲存格的背景顏色綁定到View Model端的屬性 --> <igDP:Field.CellBindings> <igDP:CellBinding Property="Background" Target="CellValuePresenter" Binding="{Binding Path=DataItem.Value1Color}" /> </igDP:Field.CellBindings> </igDP:Field> </igDP:FieldLayout.Fields> </igDP:FieldLayout> </igDP:XamDataGrid.FieldLayouts> </igDP:XamDataGrid>
