TagMapInfo Class

Contains a single configuration tag remapping statement. This class cannot be inherited.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

public sealed class TagMapInfo : ConfigurationElement

The TagMapInfo type exposes the following members.

  NameDescription
Public methodTagMapInfoInitializes a new instance of the TagMapInfo class based on the passed property values.

  NameDescription
Public propertyCurrentConfigurationGets a reference to the top-level Configuration instance that represents the configuration hierarchy that the current ConfigurationElement instance belongs to. (Inherited from ConfigurationElement.)
Public propertyElementInformationGets an ElementInformation object that contains the non-customizable information and functionality of the ConfigurationElement object. (Inherited from ConfigurationElement.)
Protected propertyElementPropertyGets the ConfigurationElementProperty object that represents the ConfigurationElement object itself. (Inherited from ConfigurationElement.)
Protected propertyItem[ConfigurationProperty]Gets or sets a property or attribute of this configuration element. (Inherited from ConfigurationElement.)
Protected propertyItem[String]Gets or sets a property, attribute, or child element of this configuration element. (Inherited from ConfigurationElement.)
Public propertyLockAllAttributesExceptGets the collection of locked attributes. (Inherited from ConfigurationElement.)
Public propertyLockAllElementsExceptGets the collection of locked elements. (Inherited from ConfigurationElement.)
Public propertyLockAttributesGets the collection of locked attributes (Inherited from ConfigurationElement.)
Public propertyLockElementsGets the collection of locked elements. (Inherited from ConfigurationElement.)
Public propertyLockItemGets or sets a value indicating whether the element is locked. (Inherited from ConfigurationElement.)
Public propertyMappedTagTypeGets or sets the name of the type to which the tag is remapped.
Protected propertyPropertiesGets the collection of properties. (Inherited from ConfigurationElement.)
Public propertyTagTypeGets or sets the name of the original type for the tag that is being remapped.

  NameDescription
Protected methodDeserializeElementReads XML from the configuration file. (Inherited from ConfigurationElement.)
Public methodEqualsCompares this instance to another object. (Overrides ConfigurationElement.Equals(Object).)
Public methodGetHashCodeReturns a hash value for the current instance. (Overrides ConfigurationElement.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodInitSets the ConfigurationElement object to its initial state. (Inherited from ConfigurationElement.)
Protected methodInitializeDefaultUsed to initialize a default set of values for the ConfigurationElement object. (Inherited from ConfigurationElement.)
Protected methodIsModifiedIndicates whether this configuration element has been modified since it was last saved or loaded, when implemented in a derived class. (Inherited from ConfigurationElement.)
Public methodIsReadOnlyGets a value indicating whether the ConfigurationElement object is read-only. (Inherited from ConfigurationElement.)
Protected methodResetResets the internal state of the ConfigurationElement object, including the locks and the properties collections. (Inherited from ConfigurationElement.)
Protected methodResetModifiedResets the value of the IsModified method to false when implemented in a derived class. (Inherited from ConfigurationElement.)
Protected methodSerializeElementWrites the contents of this configuration element to the configuration file when implemented in a derived class. (Inherited from ConfigurationElement.)
Protected methodSerializeToXmlElementWrites the outer tags of this configuration element to the configuration file when implemented in a derived class. (Inherited from ConfigurationElement.)
Protected methodSetReadOnlySets the IsReadOnly property for the ConfigurationElement object and all subelements. (Inherited from ConfigurationElement.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Protected methodUnmergeModifies the ConfigurationElement object to remove all values that should not be saved. (Inherited from ConfigurationElement.)

The TagMapInfo class allows you to remap the types of tags at compile time. This remapping causes the mapped type to be used in place of the original tag type for all pages and controls in the ASP.NET application in the scope of the configuration file.

The TagMapCollection class allows you to programmatically access and modify the tagMapping subsection of the pages section of a configuration file. Within the tagMappings subsection, you can add and remove mappings between tag types by specifying the fully qualified strong names of the types.

NoteNote

Unlike other attributes and collections in the pages section, tag remapping has no matching ASP.NET page directive.

The following configuration file excerpt shows how to declaratively specify values for several properties of the TagMapInfo class.

<system.web>
  <pages>
    <tagMapping>
      <add
        tagType=
          "System.Web.UI.WebControls.WebParts.WebPartManager"
        mappedTagType=
          "Microsoft.Sharepoint.WebPartPartManager, 
           MSPS.Web.dll, Version='2.0.0.0'" 
      />
    </tagMapping>
  </pages>
</system.web>

The following code example shows how to use the TagMapCollection class to programmatically modify tag-mapping settings. This code example is part of a larger example provided for the PagesSection class.

// Get all current TagMappings in the collection. 
for (int i = 0; i < pagesSection.TagMapping.Count; i++)
{
  Console.WriteLine("TagMapping {0}:", i);
  Console.WriteLine("  TagTypeName = '{0}'",
      pagesSection.TagMapping[i].TagType);
  Console.WriteLine("  MappedTagTypeName = '{0}'",
      pagesSection.TagMapping[i].MappedTagType);
}

// Add a TagMapInfo object using a constructor.
pagesSection.TagMapping.Add(
    new System.Web.Configuration.TagMapInfo(
    "MyNameSpace.MyControl", "MyNameSpace.MyOtherControl"));
