Question

我正在构建一个silverlight webpart。我只是想在文本块中显示共享点列表数据与数据网格，因为我只打算从列表中返回一个项目。我已经设法在数据网格中获得了我想要的结果，但我不确定如何修改我的代码，以便我可以在文本块中显示我的数据。

我认为我可以写简单

texblock1.text = projects;

但它会引发错误。

            dataGrid1.ItemsSource = projects; // must be on UI thread        
        }    
    }
}

要在UI线程中运行代码，请使用以下代码：

Dispatcher.BeginInvoke(() => {
    //add code here to which are to be executed on the UI thread
});
