Examples

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

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

' Get all current TagMappings in the collection.
Dim k As Int32
For k = 1 To pagesSection.TagMapping.Count
  Console.WriteLine("TagMapping {0}:", i)
  Console.WriteLine("  TagTypeName = '{0}'", _
   pagesSection.TagMapping(k).TagType)
  Console.WriteLine("  MappedTagTypeName = '{0}'", _
   pagesSection.TagMapping(k).MappedTagType)
Next

' Add a TagMapInfo object using a constructor.
pagesSection.TagMapping.Add( _
 New System.Web.Configuration.TagMapInfo( _
 "MyNameSpace.MyControl", "MyNameSpace.MyOtherControl"))

Remarks

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 tagMapping subsection, you can add and remove mappings between tag types by specifying the fully qualified strong names of the types.

Note

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