我很新于MVVM,目前遇到了数据绑定的问题。我的视图页面上有一个按钮,它可以动态地创建文本框,但我不知道如何将这些文本框与ViewModel中的List进行绑定。
在我的视图中,我有以下代码:
<Button x:Name="btWebsite" Grid.ColumnSpan="2" Width="50" Height="50" Click="btWebsite_Click" Margin="23,245,259,202">
<StackPanel x:Name="pnWebsiteButton" Orientation="Horizontal">
<Image x:Name="imgWebsite" Source= "Images/webIcon.jpg" Stretch="Fill" HorizontalAlignment="Left" VerticalAlignment="Top"/>
</StackPanel>
</Button>
<GroupBox x:Name="grpWebsite" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="73,245,0,0" Grid.ColumnSpan="2" Height="51" Width="170" BorderBrush="{x:Null}" BorderThickness="0">
<ScrollViewer x:Name="pnScrollWebsite" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" Margin="0,0,0,-6">
<StackPanel x:Name="pnWebsite" Orientation="Vertical" Grid.ColumnSpan="2" HorizontalAlignment="Left" Margin="1,2,0,0" VerticalAlignment="Top" IsEnabled="True">
</StackPanel>
</ScrollViewer>
</GroupBox>
private void btWebsite_Click(object sender, RoutedEventArgs e)
{
var newTextBox = new TextBox();
newTextBox.Text = "type the website address...";
newTextBox.Foreground = Brushes.Gray;
newTextBox.Width = 150;
newTextBox.Name = "txtWebsite" + iWebsites;
pnWebsite.Children.Add(newTextBox);
pnWebsite.RegisterName(newTextBox.Name, newTextBox);
iWebsites++;
}
在我的ViewModel中,我有:
public List<string> Websites
{
get { return _websites; }
set
{
if (value != _websites)
{
_websites = value;
OnPropertyChanged("Websites");
}
}
}
我很难理解如何将网站文本框添加到视图模型列表中。谢谢您的帮助。
ItemsControl
:<ItemsControl ItemsSource="{Binding Path=Websites}"/>
。将Websites设置为ObservableCollection<string>
,向集合中添加字符串 - 它将在视图中显示。 - ASh
