在FlexGrid中通过IValueConverter实现数据类型的转换

本文主要演示通过 IValueConverter 实现 int 与 bool 类型之间的转换。

主要实现方法是，首先继承IValueConverter实现一个自己的数据转换类型，BoolValueConverter的功能是判断该员工是否是五年以上工龄

public class BoolValueConverter : IValueConverter
    {

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            Int32 seniority = -1;
            if (Int32.TryParse(value.ToString(),out seniority))
            {
                if (seniority < 5)
                {
                    return false;
                }
                else
                {
                    return true;
                }
            }
            return false;
        }

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

然后将BoolValueConverter 设置给Flexgrid的【五年以上工龄】列

<c1:C1FlexGrid Name="c1FlexGrid1"
                    Margin="10,10,0,0"
                    HorizontalAlignment="Left"
                    VerticalAlignment="Top"
                    AutoGenerateColumns="False">
        <c1:C1FlexGrid.Columns>
            <c1:Column Binding="{Binding Code}" Header="员工编号" />
            <c1:Column Binding="{Binding Name}" Header="姓名" />
            <c1:Column Binding="{Binding Seniority, Mode=TwoWay}" Header="工龄" />
            <c1:Column Header="五年以上工龄">
                <c1:Column.CellTemplate>
                    <DataTemplate>
                        <CheckBox Name="checkBox1"
                                    Content="五年以上工龄"
                                    IsChecked="{Binding Seniority,
                                                        Converter={StaticResource BoolValueConverter}}" />
                    </DataTemplate>
                </c1:Column.CellTemplate>
            </c1:Column>
        </c1:C1FlexGrid.Columns>
    </c1:C1FlexGrid>
