以下工具提示代码可在WPF中使用.
我正在尝试使其在Silverlight中工作.
但这给了我这些错误:
TextBlock does not contain a definition for ToolTip.
Cursors does not contain a definition for Help.
ToolTipService does not contain a definition for SetInitialShowDelay.
我如何才能在Silverlight中使用它?
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;
namespace TestHover29282
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
AddCustomer("Jim Smith");
AddCustomer("Joe Jones");
AddCustomer("Angie Jones");
AddCustomer("Josh Smith");
}
void AddCustomer(string name)
{
TextBlock tb = new TextBlock();
tb.Text = name;
ToolTip tt = new ToolTip();
tt.Content = "This is some info on " + name + ".";
tb.ToolTip = tt;
tt.Cursor = Cursors.Help;
ToolTipService.SetInitialShowDelay(tb, 0);
MainStackPanel.Children.Add(tb);
}
}
}
解决方法:
使用ToolTipService提供的附加属性将工具提示添加到Silverlight控件. Silverlight的版本中没有SetInitialShowDelay,在Cursors类型上也没有帮助光标.
void AddCustomer(string name)
{
TextBlock tb = new TextBlock();
tb.Text = name;
ToolTip tt = new ToolTip();
tt.Content = "This is some info on " + name + ".";
ToolTipService.SetToolTip(tb, tt);
MainStackPanel.Children.Add(tb);
}
