gridview裡面使用代理類

1.是否是中介列顯示不顯示控制

2.資料轉換控制

3.將金額轉化為萬元

 

 

1.telerik裡面的gridview，資料行繫結bool類型的時候（最簡單的方式綁定），頁面直接顯示checkbox

2.只要在GV列裡面使用轉換器，必須使用代理：比如isvisible，isreadonly的時候是必須的，
代碼格式：
 IsVisible="{Binding Path=DataSource.IsIntermediaryVisable,Mode=TwoWay,Source={StaticResource DataContextProxy}}" 

但是把數字轉化為其他格式的時候使用下面格式即可：
<TR:GridViewDataColumn  IsReadOnly="True"  Header="送審金額(萬元)" IsFilterable="False" Width="3*"  DataMemberBinding="{Binding SongShenMoney,Converter={StaticResource MoneyConverter}}" DataFormatString="{}{0:c}"  HeaderTextAlignment="Center" />

 

   <Grid x:Name="LayoutRoot" Background="White">
        <Grid.Resources>
            <SlCommon:DataContextProxy x:Key="DataContextProxy" />   //引入代理      

        </Grid.Resources>

 

   <TR:RadGridView x:Name="ProjectGrid"  ItemsSource="{Binding PageView,Mode=TwoWay}"
                            AutoGenerateColumns="False"
                            ShowGroupPanel="False" 
                            IsReadOnly="True"
                            IsFilteringAllowed="False"
                            CanUserReorderColumns="False"
                            CanUserFreezeColumns="False"
                            CanUserSortColumns="False">
                <TR:RadGridView.Columns>
                    <TR:GridViewColumn Width="80" Header="操作" HeaderTextAlignment="Center">
                        <TR:GridViewColumn.CellTemplate>
                            <DataTemplate >
                                <StackPanel Orientation="Horizontal">
                                    <HyperlinkButton  x:Name="Select"  Tag="{Binding}"  CommandParameter="{Binding}" Command="{Binding Source={StaticResource DataContextProxy} ,Path=DataSource.SelectCommand}" >
                                        <HyperlinkButton.Content>
                                            <Image x:Name="btnViewDetail" Source="/Resources/edit.png" Width="16" Height="16"  Margin="5,0,0,0" Cursor="Hand" ToolTipService.ToolTip="修改"/>
                                        </HyperlinkButton.Content>
                                    </HyperlinkButton>
                                    <TR:RadToolBarSeparator/>
                                    <HyperlinkButton  x:Name="delete"  Tag="{Binding}"  CommandParameter="{Binding}" Command="{Binding Source={StaticResource DataContextProxy} ,Path=DataSource.DeleteCommand}" >
                                        <HyperlinkButton.Content>
                                            <Image x:Name="btndelete" Source="/Resources/do_delete.png" Width="16" Height="16"  Margin="5,0,0,0" Cursor="Hand" ToolTipService.ToolTip="刪除"/>
                                        </HyperlinkButton.Content>
                                    </HyperlinkButton>
                                </StackPanel>
                            </DataTemplate>
                        </TR:GridViewColumn.CellTemplate>
                    </TR:GridViewColumn>
                    <TR:GridViewDataColumn  DataMemberBinding="{Binding Code}" HeaderTextAlignment="Center"  Header="編碼"  Width="100"></TR:GridViewDataColumn>
                    <TR:GridViewDataColumn  DataMemberBinding="{Binding Name}" HeaderTextAlignment="Center" Header="名稱"   Width="150"></TR:GridViewDataColumn>
                    <TR:GridViewDataColumn  DataMemberBinding="{Binding DSort}" HeaderTextAlignment="Center" Header="排序" Width="50"></TR:GridViewDataColumn>
                    <TR:GridViewDataColumn   IsVisible="{Binding Path=DataSource.IsIntermediaryVisable,Mode=TwoWay,Source={StaticResource DataContextProxy}}" 

                       DataMemberBinding="{Binding IsIntermediarybool,Mode=TwoWay}" HeaderTextAlignment="Center" Header="是否是中介" Width="50"></TR:GridViewDataColumn>
                    <TR:GridViewColumn Header="是否停用" Width="70" HeaderTextAlignment="Center" >
                        <TR:GridViewColumn.CellTemplate>
                            <DataTemplate >
                                <CheckBox  IsChecked="{Binding Isdisabled,Mode=TwoWay}" Command="{Binding Source={StaticResource DataContextProxy} ,Path=DataSource.IsdisabledCommand}" CommandParameter="{Binding}"/>
                            </DataTemplate>
                        </TR:GridViewColumn.CellTemplate>
                    </TR:GridViewColumn>

                </TR:RadGridView.Columns>
            </TR:RadGridView>

 

後置代碼
   private bool _isIntermediarybool;
        public bool IsIntermediarybool
        {
            get { return _isIntermediarybool; }
            set
            {
                if (!ReferenceEquals(_isIntermediarybool, value))
                {
                    _isIntermediarybool = value;
                    OnPerprotyChange("IsIntermediarybool");
                }
            }
        }

3.轉化器的定義：

1 常用轉換器

  public class DataContextProxy : FrameworkElement    {        public DataContextProxy()        {            this.Loaded += new RoutedEventHandler(DataContextProxy_Loaded);        }        void DataContextProxy_Loaded(object sender, RoutedEventArgs e)        {            Binding binding = new Binding();            if (!String.IsNullOrEmpty(BindingPropertyName))            {                binding.Path = new PropertyPath(BindingPropertyName);            }            binding.Source = this.DataContext;            binding.Mode = BindingMode;            this.SetBinding(DataContextProxy.DataSourceProperty, binding);        }        public Object DataSource        {            get { return (Object)GetValue(DataSourceProperty); }            set { SetValue(DataSourceProperty, value); }        }        public static readonly DependencyProperty DataSourceProperty =            DependencyProperty.Register("DataSource", typeof(Object), typeof(DataContextProxy), null);        public string BindingPropertyName { get; set; }        public BindingMode BindingMode { get; set; }    }

 

 

2 金額轉換

    public class MoneyConverter : IValueConverter    {        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)        {            if (value == null)                return 0;            decimal result;            if (Decimal.TryParse(value.ToString(), out result))            {                return Math.Round(result / 10000, 2);            }            else            {                return 0;            }        }        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)        {            return value;        }    }
