<Style TargetType="Button" 1 >
<Setter Property="Background" 2
Value="Red" 3 />
</Style>
1) Type type = xamlTypeResolver.Resolve("Button");
2) Value of Style.TargetType determined by calling
IAmbientProvider to find instances of Style.TargetType up the
parse stack.
3)
xamlSchemaContext = ixscp.SchemaContext;
xamlType = xamlSchemaContext.GetXamlType(typeof(Button));
xamlMember = xamlType.GetMember("Background");
value=xamlMember.TypeConverter.ConverterInstance.ConvertFrom(…);
<Button Click=“foo” 1 />
<Button
2
Click=“{l:EventWire foo}” />
<Button Height=“{l:GetValue 3
tb1.Height}” />
1) Parser looks for foo method on Root object.
2) IRootObjectProvider can get root object.
3) IXamlNameResolver can find element with Name of tb1 (even it is
hasn’t been parsed yet).
