我有一个非常奇怪的问题,我似乎无法弄清楚。如果我尝试像在网格内部的绑定下面的第一个代码一样绑定,则无效。
<Controls:Flyout IsOpen="{Binding Ui.EditGameFlyOut, Mode=TwoWay}" Header="{Binding SelectedGame.Id, StringFormat='Edit Game [{0}]'}" Position="Right" Theme="Dark" Width="300">
<ScrollViewer>
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="200" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Button Width="100" Content="Save" Cursor="Hand" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,0,0,10" />
<Label Grid.Row="1">Title</Label>
<TextBox Grid.Row="2" Text="{Binding SelectedGame.Title, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Column="1" Margin="0,0,0,10" />
<Label Grid.Row="3">Release date</Label>
<DatePicker Grid.Row="4" Margin="0,0,0,10" SelectedDate="{Binding DatePickerDate}" />
<Label Grid.Row="5">Overview</Label>
<TextBox Grid.Row="6" Text="" Grid.Column="1" Margin="0,0,0,10" />
</Grid>
</ScrollViewer>
</Controls:Flyout>
但是,如果我像第二个代码段一样删除网格控件,则没有问题。为什么会发生这种情况?
<Controls:Flyout IsOpen="{Binding Ui.EditGameFlyOut, Mode=TwoWay}" Header="{Binding SelectedGame.Id, StringFormat='Edit Game [{0}]'}" Position="Right" Theme="Dark" Width="300">
<ScrollViewer>
<TextBox Grid.Row="2" Text="{Binding SelectedGame.Title, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Grid.Column="1" Margin="0,0,0,10" />
</ScrollViewer>
</Controls:Flyout>
我觉得这真的很奇怪……
我在大量研究后设法修复了它。
我要做的就是将数据台面放在网格上,例如下面的代码。
<Controls:Flyout IsOpen="{Binding Ui.EditGameFlyOut, Mode=TwoWay}" Header="{Binding SelectedGame.Id, StringFormat='Edit Game [{0}]'}" Position="Right" Theme="Dark" Width="300">
<ScrollViewer>
<Grid Margin="10" DataContext="{Binding SelectedGame}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="200" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Button Width="100" Content="Save" Cursor="Hand" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,0,0,10" />
<Label Grid.Row="1">Title</Label>
<TextBox Grid.Row="2" Text="{Binding Title, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Margin="0,0,0,10" />
<Label Grid.Row="3">Release date</Label>
<DatePicker Grid.Row="4" Margin="0,0,0,10" SelectedDate="{Binding DatePickerDate}" />
<Label Grid.Row="5">Overview</Label>
<TextBox Grid.Row="6" Text="" Margin="0,0,0,10" />
</Grid>
</ScrollViewer>
</Controls:Flyout>
