上一篇《WPF 4 DataGrid 控件(进阶篇一)》中我们通过DataGridTemplateColumn 类自定义编辑了日期列的样式,当然也可以根据个人需要设置任何样式模板。上例中Pass Exam 列显示学生是否通过考试,但我们并不知道该学生每门学科的成绩是多少。本篇将为DataGrid 行增加这些详细信息,使得DataGrid 数据更加充实。
首先,我们仍然先更新一下Member 类,增加Math 和History 两门学科:
public class Member
{
public string Name { get; set; }
public string Age { get; set; }
public SexOpt Sex { get; set; }
public bool Pass { get; set; }
public DateTime ExamDate { get; set; }
public Uri Email { get; set; }
public int Math { get; set; }
public int History { get; set; }
}
为学生赋上考试成绩:
… …
memberData.Add(new Member()
{
Name = "Lucy",
Age = "25",
Sex = SexOpt.Female,
Pass = true,
ExamDate = new DateTime(2010, 4, 10),
Email = new Uri("mailto:Lucy@school.com"),
Math = 80,
History = 85
});
dataGrid.DataContext = memberData;
接下来就要到XAML 中为考试成绩设计样式模板:
<Window.Resources>
... ...
<DataTemplate x:Key="RowDetails">
<Border BorderThickness="0" Background="Orchid" Padding="10">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBlock Text="Math: " VerticalAlignment="Center"/>
<TextBlock Text="{Binding Math}" VerticalAlignment="Center"
FontSize="15" FontWeight="Bold"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="History: " VerticalAlignment="Center"/>
<TextBlock Text="{Binding History}" VerticalAlignment="Center"
FontSize="15" FontWeight="Bold"/>
</StackPanel>
</StackPanel>
</Border>
</DataTemplate>
</Window.Resources>
在<DataGrid>中为RowDetailsTemplate 属性添加RowDetails 模板:
<DataGrid x:Name="dataGrid" ItemsSource="{Binding}"
AutoGenerateColumns="False" SelectionUnit="CellOrRowHeader"
RowDetailsTemplate="{StaticResource RowDetails}">
… …
当然,我们也可以直接在<DataGrid>中添加<DataGrid.RowDetailsTemplate> 完成上面所有XAML 代码。注:上面代码中<DataGrid>的RowDetailsTemplate 属性要清除。
... ...
<DataGrid.RowDetailsTemplate>
<DataTemplate>
<Border BorderThickness="0" Background="Orchid" Padding="10">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBlock Text="Math: " VerticalAlignment="Center"/>
<TextBlock Text="{Binding Math}" VerticalAlignment="Center"
FontSize="15" FontWeight="Bold"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="History: " VerticalAlignment="Center"/>
<TextBlock Text="{Binding History}" VerticalAlignment="Center"
FontSize="15" FontWeight="Bold"/>
</StackPanel>
</StackPanel>
</Border>
</DataTemplate>
</DataGrid.RowDetailsTemplate>
... ...
编译程序,点击行头显示详细考试成绩数据。完成这几篇开发后,我们的DataGrid 内容是不是充实了很多。
