如果我忽略了某些内容,请提前道歉-我仍然发现我的脚在使用Xaml而不是Windows窗体.
我正在尝试将数据源绑定到DataGrid,其中列之一是复选框.我的原始解决方案可以很好地解决此问题,但是需要用户双击复选框:
<Window x:Class="ExecBoxInvoices.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="507" Width="676">
<Grid Margin="0,0,0,51">
<DataGrid x:Name="InvoiceDG" HorizontalAlignment="Left" Height="165" Margin="134,251,0,0" VerticalAlignment="Top" Width="400" ItemsSource="{Binding}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridCheckBoxColumn Header="Generate" Binding="{Binding Generate}" Width="80"/>
<DataGridTextColumn Header="Table_Number" Binding="{Binding Table_Number}" Width="120"/>
<DataGridTextColumn Header="Transaction_Date" Binding="{Binding Transaction_Date}" Width="175"/>
<DataGridTextColumn Header="Transaction_ID" Visibility="Hidden" Binding="{Binding Transaction_ID}"/>
</DataGrid.Columns>
</DataGrid>
</Grid>
单击复选框的新解决方案显示在下面,但不起作用(错误显示在Binding =“ {Binding Generate}”上):
<Window x:Class="ExecBoxInvoices.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="507" Width="676">
<Grid Margin="0,0,0,51">
<DataGrid x:Name="InvoiceDG" HorizontalAlignment="Left" Height="165" Margin="134,251,0,0" VerticalAlignment="Top" Width="400" ItemsSource="{Binding}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Generate" Width="60" Binding="{Binding Generate}">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox IsChecked="{Binding Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTextColumn Header="Table_Number" Binding="{Binding Table_Number}" Width="120"/>
<DataGridTextColumn Header="Transaction_Date" Binding="{Binding Transaction_Date}" Width="175"/>
<DataGridTextColumn Header="Transaction_ID" Visibility="Hidden" Binding="{Binding Transaction_ID}"/>
</DataGrid.Columns>
</DataGrid>
</Grid>
作为参考,用于设置源的代码为:
InvoiceDG.ItemsSource = recordCollection;
其中recordCollection是以下内容的列表:
class InvoiceRow
{
public bool Generate { get; set; }
public string Table_Number { get; set; }
public string Transaction_Date { get; set; }
public string Transaction_ID { get; set; }
public InvoiceRow(bool generate, string table_Number, string transaction_Date, string transaction_ID)
{
this.Generate = generate;
this.Table_Number = table_Number;
this.Transaction_Date = transaction_Date;
this.Transaction_ID = transaction_ID;
}
}
解决方法:
尝试这个:
<DataGridTemplateColumn Header="Generate" Width="60">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox IsChecked="{Binding Generate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
