WPF enumeration value as ObjectDataProvider's method parameter
I want to pass for as a parameter for the GetValues method from MyItemSourceProvide开发者_如何学Pythonr a concrete value of MyEnum. How to write it please?
<ObjectDataProvider MethodName="GetValues" ObjectType="{x:Type local:MyItemSourceProvider}">
<ObjectDataProvider.MethodParameters>
<!-- ENUM value (e.g. MyEnum.Record1) -->
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
method:
public System.Collections.IEnumerable GetValues(MyEnum key) {}
public enum MyEnum {Record1, ...}
You can implement it as following:
<ObjectDataProvider MethodName="GetValues"
ObjectType="{x:Type local:MyItemSourceProvider}"
x:Key="getValues">
<ObjectDataProvider.MethodParameters>
<local:MyEnum>Record1</local:MyEnum>
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
or you can also do it in this way:
<ObjectDataProvider MethodName="GetValues"
ObjectType="{x:Type local:MyItemSourceProvider}"
x:Key="getValues">
<ObjectDataProvider.MethodParameters>
<x:Static Member="local:MyEnum.Record1" />
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
with:
public enum MyEnum {Record1, Record2, ...}
Try this:
<Window.Resources>
<local:MyEnum x:Key="valueToPassIn">Record1</local:MyEnum>
<x:Type x:Key="typeToPassIn" TypeName="local:MyEnum" />
<ObjectDataProvider MethodName="GetValues"
ObjectType="{x:Type sys:Enum}"
x:Key="ExampleEnumValues"
MethodParameters="{StaticResource valueToPassIn}">
</ObjectDataProvider>
</Window.Resources>
