C# 无法在Silverlight DataGrid列中应用字符串格式

我有一个数据网格。其项目源设置为列表。我的问题是我无法应用字符串格式。这是我试过的。我错过什么了吗？ StringFormat='MM/dd/yyyy' StringFormat={0:dd-MMM-yyyy}

                        <sdk:DataGridTemplateColumn   Header="Recieved Date" Width="Auto"  >
                            <sdk:DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Path=RecievedDate, StringFormat=\{0:dd-MMM-yyyy\} }" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellTemplate>
                            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                                <DataTemplate>
                                    <sdk:DatePicker Name="dtpFinancialAndComplianceLog" Text="{Binding Path=RecievedDate,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellEditingTemplate>
                        </sdk:DataGridTemplateColumn>

如果我理解您试图正确执行的操作，那么您有一个DataGrid列，希望以特定格式显示DateTime对象。通常，DateTime对象将根据System.Threading.Thread.CurrentUICulture对自己的格式进行排序

                        <sdk:DataGridTemplateColumn   Header="Recieved Date" Width="Auto"  >
                            <sdk:DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Path=RecievedDate, StringFormat=\{0:dd-MMM-yyyy\} }" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellTemplate>
                            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                                <DataTemplate>
                                    <sdk:DatePicker Name="dtpFinancialAndComplianceLog" Text="{Binding Path=RecievedDate,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellEditingTemplate>
                        </sdk:DataGridTemplateColumn>

据我所知，将任何对象强制转换为特定格式的最简单方法是使用自定义IValueConverter：

                        <sdk:DataGridTemplateColumn   Header="Recieved Date" Width="Auto"  >
                            <sdk:DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Path=RecievedDate, StringFormat=\{0:dd-MMM-yyyy\} }" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellTemplate>
                            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                                <DataTemplate>
                                    <sdk:DatePicker Name="dtpFinancialAndComplianceLog" Text="{Binding Path=RecievedDate,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellEditingTemplate>
                        </sdk:DataGridTemplateColumn>

namespace MyProject.Converters
{
    public class FormatConverter : IValueConverter
    {//Suitable only for read-only data

        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if (value == null)
                return string.Empty;
            if(string.IsNullOrEmpty(parameter.ToString()))
                return value.ToString();

            return string.Format(culture, parameter.ToString(), value);
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return null;
        }
    }
}

将命名空间添加到xaml:

xmlns:conv=“clr namespace:MyProject.Converters”

并在控件的资源中声明转换器后，需要使用新转换器绑定列的数据：

                        <sdk:DataGridTemplateColumn   Header="Recieved Date" Width="Auto"  >
                            <sdk:DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Path=RecievedDate, StringFormat=\{0:dd-MMM-yyyy\} }" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellTemplate>
                            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                                <DataTemplate>
                                    <sdk:DatePicker Name="dtpFinancialAndComplianceLog" Text="{Binding Path=RecievedDate,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellEditingTemplate>
                        </sdk:DataGridTemplateColumn>

<TextBlock Text="{Binding Path=RecievedDate, Converter={StaticResource Formatter}, ConverterParameter=\{0:dd-MMM-yyy\} }" />
