1、xmlns
Mapping URI的格式是clr-namespace:<clr namespace>[;assembly=<assembly name>]
xmlns:converter="clr-namespace:Pansoft.SCV.Workflows.OpenAccount.ValueConverter"
(2)如果自定义类和XAML处在不同的Assembly之中。除了clr-namespace值外,还必须提供assembly的值。
xmlns:converter="clr-namespace:Pansoft.SCV.UIFramework.ValueConverter;assembly=Pansoft.SCV.UIFramework"
clr-namespace和assembly的拼写必须都是小写。
这样在XAML中就可以通过namespace prefix和类名使用自定义的元素了。举例:
<converter:ImageSourceConverter x:Key="ImageConverter"/>
2、Resource
前台:
<Page.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/Pansoft.SCV.UIFramework;component/Style/GlobaStyle.xaml"/> </ResourceDictionary.MergedDictionaries> <converter:ImageSourceConverter x:Key="ImageConverter"/> <Style TargetType="{x:Type TextBox}"> </Style> </ResourceDictionary> </Page.Resources>
Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = new Uri("../Pansoft.SCV.Workflows.OpenAccount;component/Style/GlobaStyle.xaml", UriKind.Relative) });
Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = new Uri("pack://application:,,,/Pansoft.SCV.Workflows.OpenAccount;component/Style/GlobaStyle.xaml") });
3、Binding
前台:
<trans:OpenAccountTranscation x:Key="WorkflowNode"/>
或者
Resources.Add("WorkflowNode", node.Owner.Transcation);
调用:
<Page.DataContext> <Binding Source="{StaticResource WorkflowNode}"/> </Page.DataContext>
<TextBlock Text="{Binding Name}" FontSize="18" Margin="20,0"/>
或者直接写:
DataContext = node.Owner.Transcation;
后台:
Binding MyBinding = new Binding(); MyBinding.Path = new PropertyPath("Name"); MyBinding.Mode = BindingMode.OneWay; MyBinding.Source = node.Owner.Transcation; MyTextBlock.DataContext = node.Owner.Transcation; MyTextBlock.SetBinding(TextBlock.TextProperty, MyBinding);
4、后台重新绑定
xaml:
<Button x:Name="BtnSwitchLangs" Content="{DynamicResource Execute}" Width="200" Height="60" Click="Button_Click_2" Margin="0,5"/>
BtnSwitchLangs.SetResourceReference(ContentProperty, "ReExecute");//为内容绑定新的源
