Trying out the XmlDataSource block with 2 dependable DropDownLists.
I have 2 Divisions: Div1 and Div2. I want to populate my Countries DropDownList depending on my choice of Division.
The countries XmlDataSource is easy.
<my:XmlDataSource my:Name="countries">
<Countries>
<Div1>
<CountryName Code="Finland" Name="Finland"/>
<CountryName Code="Sweden" Name="Sweden"/>
</Div1>
<Div2>
<CountryName Code="Greece" Name="Greece"/>
<CountryName Code="Ireland" Name="Ireland"/>
</Div2>
</Countries>
</my:XmlDataSource>
However using it is not so easy.
My CountryName control is
<my:Control my:Name="CountryName" my:TypeName="UocDropDownList" my:Caption="{Binding Source=schema, Path=CountryName.DisplayName}" my:Description="{Binding Source=schema, Path=CountryName.Description}">
<my:Properties>
<my:Property my:Name="Required" my:Value="{Binding Source=schema, Path=CountryName.Required}"/>
<my:Property my:Name="Columns" my:Value="40"/>
<my:Property my:Name="ValuePath" my:Value="@Code"/>
<my:Property my:Name="CaptionPath" my:Value="@Name"/>
<my:Property my:Name="HintPath" my:Value="Hint"/>
<my:Property my:Name="ItemSource" my:Value="{Binding Source=countries, Path=/Countries/<what goes here??>/*, Mode=OneWay}"/>
<my:Property my:Name="SelectedValue" my:Value="{Binding Source=object, Path=CountryName, Mode=TwoWay}"/>
</my:Properties>
</my:Control>
If I plug the fixed text Div1 into my Path e.g. Path=/Countries/Div1/* I see (even before I enter my choice of Division) the available countries as Finland and Sweden. But I want to push the dynamically selected value of Division into my path. %Attribute_Division%
doesnt seem to help me. Hopefully this value is available in some meta-data in the RCDC form..
What is the trick to push that value just picked off the list into a dependent DropDownLists source path??
