in example is a xml file with data from database. now i need to bind it to some fields...
i use the XMLDataProvider here
<Grid.DataContext>
<XmlDataProvider x:Name="dataxml" XPath="EssenceList/Essence" Source="464.xml"/>
</Grid.DataContext>
and mostof simple texboxes i bind like
<TextBox Text="{Binding XPath=/EssenceList/Essence/LinkedEssences/LinkType[1]/LinkedEssence/@GUID}" />
but now i need to bind a combobox this way:
- the first Essence in the document contains LinkedEssences, that contains and
- in document below there is a full description for it that contains the NAME property i need
????-22
UKPG22
0
and many other available Essences for this combobox
i managed to bind the list of thems to combobox
<ComboBox ItemTemplate="{StaticResource rolelistTemplate}" ItemsSource="{Binding XPath=/EssenceList/Essence[@Type]}" />
so it displays it well, but i can't bind it to my LinkedEssences.
