Question

以下是我的日期选择器，我想在我的xaml.cs中添加这行代码

dtTierValidTo.BlackOutDates.AllDaysinPast();

以下是我在xaml中的datepicker代码

<DatePicker BorderBrush="LightBlue" BorderThickness="1" 
  Name="dtTierValidTo" Opacity="false" IsEnabled="{Binding CanEdit}"  DisplayDateStart="{Binding TierDealValidFromDate, Mode=TwoWay}"   
SelectedDate="{x:Static sys:DateTime.Now}" DisplayDate="{x:Static sys:DateTime.Now}" 
 Width="120" HorizontalAlignment="Left">
    </DatePicker>

我的整个代码如下面的xaml，datepicker在网格中是DataGridTemplateColumn

<DataGridTemplateColumn Width="140"  Header="Tier Valid To">
                            <DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding TierDealValidToDateDisplayText}"/>
                                    <!--<TextBlock Text="{Binding TierDealValidToDate}"></TextBlock>-->
                                </DataTemplate>
                            </DataGridTemplateColumn.CellTemplate>
                                            <DataGridTemplateColumn.CellEditingTemplate>
                                                <DataTemplate>
                                                    <Grid>
                                                        <!--<DatePicker BorderBrush="LightBlue" BorderThickness="1"

                                                                    Text="{Binding TierDealValidToDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True, TargetNullValue=''}"

只需创建一个如下所示加载的datepicker事件

in xaml

 Array[org.apache.spark.sql.Row] = Array([1,2,3,4,5,6,7,8,9,10...

xaml.cs中的

Name="datepickerName"  Loaded="datepickerName_Loaded"

如何在我的xaml中的datagridtemplate列下的网格下访问datepicker到我的xaml.cs页面？我将如何获得这个
