嗨,新的WPF程序员在这里。我似乎无法让这个工作,我希望也许你有一些想法。我想在用户定义表(ListBox)中选择一个项目时,它会将数据(ObservableCollection)填充到我的数据网格中。然后我将使用下面的“插入编辑保存”按钮进行编辑。用户定义表(ListBox)中的每个项目都有多个选项和描述。
我有一个看起来像这样的XAML:
document()
和我的模特:
<Grid HorizontalAlignment="Left" Height="505" VerticalAlignment="Top" Width="805">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="210*"/>
<ColumnDefinition Width="233*"/>
<ColumnDefinition Width="315*"/>
<ColumnDefinition Width="47*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="33*"/>
<RowDefinition Height="217*"/>
<RowDefinition Height="86*"/>
<RowDefinition Height="89*"/>
<RowDefinition Height="81*"/>
</Grid.RowDefinitions>
<ListBox x:Name="_listbox" HorizontalAlignment="Left" Height="103" VerticalAlignment="Top" Width="210" Margin="0,1,0,0" Grid.Row="1">
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="IsSelected" Value="{Binding Selected}"/>
</Style>
</ListBox.ItemContainerStyle>
<ListBoxItem Content="ARNotes" />
<ListBoxItem Content="Item2"/>
<ListBoxItem Content="Item3"/>
<ListBoxItem Content="Item4"/>
<ListBoxItem Content="Item5"/>
<ListBoxItem Content="Item6"/>
</ListBox>
<ComboBox HorizontalAlignment="Left" Height="30" Margin="4,0,0,0" VerticalAlignment="Top" Width="257" Grid.Column="2">
<ComboBoxItem Content="FromCompanyTable"/>
</ComboBox>
<DataGrid x:Name="_grid" ItemsSource="{Binding SelectedItem, ElementName=_listbox}" AutoGenerateColumns="False" Grid.ColumnSpan="2" Grid.Column="1" Margin="24,2,0,3" Grid.Row="1" >
<DataGrid.Columns>
<DataGridTextColumn x:Name="Choice" Width="*" Header="Choice" Binding="{Binding choice}"/>
<DataGridTextColumn x:Name="Descip" Width="*" Header="Description" Binding="{Binding description}"/>
</DataGrid.Columns>
</DataGrid>
