例

この例では、 webParts セクションのいくつかの属性に対して宣言的に値を指定する方法を示します。これは、 WebPartsSection クラスのメンバーとしてもアクセスできます。

次の構成ファイルの例は、 webParts セクションに対して宣言によって値を指定する方法を示しています。

<system.web>
  <webParts>
    <personalization
      defaultProvider=" AspNetSqlPersonalizationProvider ">
        <!-- Providers may only be defined at the
            application level -->
      <providers>
        <add name="AspNetSqlPersonalizationProvider"
type="System.Web.UI.WebControls.WebParts.SqlPersonalizationProvider"
        connectionStringName="LocalSqlServer"
        applicationName="/" />
      </providers>
      <authorization>
        <deny users="*" verbs="enterSharedScope" />
        <allow users="Admin" verbs="modifyState" />
      </authorization>
    </personalization>
    <transformers>
      <add name="RowToFieldTransformer"
        type="System.Web.UI.WebControls.WebParts.RowToFieldTransformer" />
      <add name="RowToFilterTransformer"
        type="System.Web.UI.WebControls.WebParts.RowToFilterTransformer" />
      <add name="RowToParametersTransformer"
