是否有一个简单的例子,说明如何用一个 com子显示一个数据网而不是一个清单? 我在尝试SO和gogle,但不断取得成果,显示如何把 com箱放在数据网中。
What is the use of default keyword in C#? Is it introduced in C# 3.0 ?

这肯定是可能的。 这是<代码>WPF的功率。
To answer your first question, "Is there a simple example of how to have a combobox show a datagrid instead of a list?" very straight: - the answer is no.
尽管如此,完成等内容有多种不同方式,如数据单(一栏)。
一种非常简单的抽样,即可以像一个数据网那样看问题,可能会改变 com贝箱的面目。
<ComboBox x:Name="cb" ItemsSource="{Binding Persons}">
<ComboBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="50" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Name}" />
<TextBlock Grid.Column="1" Text="{Binding Age}" />
</Grid>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
You can also use SharedSizeGroup
(and Grid.IsSharedSizeScope
) to synchronize the column widths accross all items resulting in a dynamic and aligned layout.
正如我说过的那样,它为我使用ComboBox来做到这一点感到.。 愿你们能够这样做:
<ToggleButton x:Name="Toggle" Width="200" Height="30" HorizontalAlignment="Center" VerticalAlignment="Top" />
<Popup IsOpen="{Binding ElementName=Toggle, Path=IsChecked}" PlacementTarget="{Binding ElementName=Toggle}" Placement="Bottom" Width="{Binding ElementName=Toggle, Path=Width}">
<DataGrid>
<DataGrid.Columns>
<DataGridTextColumn Header="Test1" />
<DataGridTextColumn Header="Test2" />
</DataGrid.Columns>
</DataGrid>
</Popup>
这当然只是一个例子,它缺乏一些特征,如自动掩埋Popup。 但是,你到了这一点。
