我在silverlight5工作,我不得不显示一个错误消息框(由我使用childwindow制作)。我使用MVVM方法和问题的情况是这样的,我必须 当出现问题时,在Model类中弹出该错误消息。
我是在模型类中执行此操作( cfw.Show()):
public static void ShowSmallMessageWithResult(string message)
{
ConfirmationWindow cfw = new ConfirmationWindow();
cfw.SetMessage(message);
cfw.Show();
}
ConfirmationWindow.xaml是:
<silvercontrols:ChildWindow x:Class="Model.MessageFolder.ConfirmationWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:silvercontrols="clr-namespace:Silverlight.Windows.Controls;assembly=Silverlight.Windows.Controls"
xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"
Title="Message" Width="Auto" Height="Auto" MouseRightButtonDown="ChildWindow_MouseRightButtonDown">
<silvercontrols:ChildWindow.Style>
<StaticResource ResourceKey="MessageBoxStyle"/>
</silvercontrols:ChildWindow.Style>
<Grid x:Name="LayoutRoot" MinWidth="360">
<StackPanel Orientation="Vertical">
<TextBlock x:Name="MessageBox" Margin="10 15 0 0" Height="Auto" FontSize="12" Text="Text" Foreground="White" TextWrapping="Wrap" HorizontalAlignment="Left" />
<StackPanel x:Name="ContentBox" Margin="10 15 0 0" Height="Auto" Orientation="Horizontal"></StackPanel>
<StackPanel Margin="0 0 0 10" Orientation="Horizontal" HorizontalAlignment="Center" Height="45">
<Button x:Name="YesBtn" Content="Yes" Width="82" HorizontalAlignment="Left" VerticalAlignment="Bottom" Style="{StaticResource ButtonStyle_Blue}"/>
<Button x:Name="NoBtn" Content="No" Margin="60 0 0 0" Width="82" HorizontalAlignment="Right" VerticalAlignment="Bottom" Style="{StaticResource ButtonStyle_Blue}"/>
</StackPanel>
</StackPanel>
</Grid>
</silvercontrols:ChildWindow>
和ConfirmationWindow.xaml.cs是:
using System.Windows;
namespace Model.MessageFolder
{
public partial class ConfirmationWindow : Silverlight.Windows.Controls.ChildWindow
{
private bool showBtnClose;
public ConfirmationWindow(bool showBtnClose = false)
{
InitializeComponent();
HasCloseButton = showBtnClose;
this.showBtnClose = showBtnClose;
NoBtn.Click += Close;
}
#region METHODS
public void SetMessage(string message)
{
MessageBox.Text = message;
}
public void AddContent(UIElement elt)
{
ContentBox.Children.Add(elt);
}
#endregion
#region EVENT_HANDLER
public void Close(object sender, RoutedEventArgs e)
{
this.Close();
}
#endregion
private void ChildWindow_MouseRightButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
e.Handled = true;
}
}
}
问题是不要弹出任何错误消息框(我的意思是这个chiildwindow)。我不知道为什么?
注意:请注意,ConfirmationWindow.xaml位于Model文件夹中。我知道这不是一个好方法,但因为它是一个现有的应用程序所以我必须用我更漂亮的{{{}替换所有MessageBox.show()
1}}
为什么不工作?如何使它工作?
