我想从我视图中的按钮(GenericReportingView.xaml)中的代码隐藏(GenericReportingView.xaml.cs)中执行命令..
GenericReportingView.xaml:
<Grid Grid.Row="0" Grid.Column="0">
<Button Content="GetReport" Command="{Binding GetReportCommand}" HorizontalAlignment="Left" Width="50" />
</Grid>
GenericReportingView.xaml.cs:
public partial class GenericReportingView
{
private DelegateCommand _getReportCommand;
public DelegateCommand GetReportCommand
{
get { return _getReportCommand ?? (_getReportCommand = new DelegateCommand(GetReport, (obj) => true)); }
}
public GenericReportingView()
{
InitializeComponent();
}
public void GetReport(object obj)
{
//Do something..
}
}
但命令没有被调用.. 任何帮助将不胜感激。
提前致谢。

您不应该绑定到代码隐藏中的属性。绑定通常用于将控件链接到视图模型中的属性(在这种情况下,它看起来不像您有视图模型)。相反,您可以使用按钮上的单击处理程序来调用您的方法:
GenericReportView.xaml:
<Grid Grid.Row="0" Grid.Column="0">
<Button Content="GetReport" Click="GetReport" HorizontalAlignment="Left" Width="50" />
</Grid>
GenericReportView.xaml.cs
public partial class GenericReportingView
{
public GenericReportingView()
{
InitializeComponent();
}
public void GetReport(object obj, RoutedEventArgs e)
{
//Do something..
}
}
