Page system

A Page is a reusable node tree that never renders on its own. Define it in Resources and use it as the Content of layouts, Dialog, TabItem, or List.

Define a Page

<Resources>
  <Resource Type="Page" Name="InfoPage">
    <Column Gap="2">
      <Text Value="标题" Weight="Bold" />
      <Text Value="{Inputs.Detail}" />
    </Column>
  </Resource>
</Resources>

Resource Type="Page" requires Name.
Page content is a normal node tree and can contain layouts, controls, Data, Tabs, Lists, and so on.
Pages do not render automatically; they enter the UI only when referenced by Content.
Page content shares the consumer’s scope: Inputs, Data, Results, and Size.

Reference a Page

Both forms are equivalent:

<Container Content="{InfoPage}" />
<Container Content="{Resources.InfoPage}" />

Content and inline children are mutually exclusive:

<!-- Correct -->
<Container Content="{InfoPage}" />

<!-- Error: Content and children cannot be combined -->
<Container Content="{InfoPage}">
  <Text Value="inline" />
</Container>

Content containers

Element	Page content requirement
`Container` / `Row` / `Column` / `Grid` / `If`	Any node tree
`Dialog`	Any node tree
`TabItem`	Any node tree
`Tabs`	Page content must consist entirely of `TabItem`
`List`	Page content must contain exactly one `ListItem`
`ListItem`	Any node tree

Nesting and limits

A Page may reference another Page through Content.
Missing Pages and A→B→A cycles are rejected.
Pages still count toward XML depth, element count, and nesting limits.
Target in a Page is still widget-level; avoid relying on duplicate Targets when the same Page is used multiple times.

Dialog example

<Resources>
  <Resource Type="Page" Name="ConfirmPage">
    <Column Gap="2">
      <Text Value="{Inputs.Message}" />
      <Row Gap="2">
        <Button Text="Close" OnClick="{Confirm.Hide}" />
      </Row>
    </Column>
  </Resource>
</Resources>

<Dialog Name="Confirm" Title="Notice" Content="{ConfirmPage}" />
<Button Text="Open" OnClick="{Confirm.Show}" />
