// Create the MouseLeftButtonUp event handler for the root Canvas object.
function onMouseLeftButtonUp(sender, eventArgs)
{
// Retrieve a reference to the plug-in.
var plugin = sender.getHost();

// Define a XAML fragment and create it.
var xamlFragment = '<TextBlock Canvas.Top="200" Text="Click for more info..." />';
textBlock = plugin.content.createFromXaml(xamlFragment, false);

// Add the XAML fragment as a child of the root Canvas object.
sender.children.add(textBlock);
}

如果希望使用 x:Name 属性值作为 XAML 段的一部分,则需要提供 XAML 命名空间引用作为 XAML 内容的一部分。例如,对于要使用 x:Name 属性值的前面的 XAML 段示例,需要按如下方式重新编写该示例:


// Define a XAML fragment and create it.
    var xamlFragment = '<TextBlock xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" ';xamlFragment += 'x:Name="myCanvas" Canvas.Top="200" Text="Click for more info" />';

    textBlock = plugin.content.createFromXaml(xamlFragment, false);
