Overview

TaxonomyWebTaggingControl represents a generic Web control for picking managed metadata terms.

During initialization two properties are mandatory to bind this control with Managed Metadata Service (MMS):

• TermStore
• TermSet

Below is presented example how to initialize it

Country picker

Let us consider the case when not all terms for the term set should be shown but a subset only. Assume we have the following structure for the countries:

• the first level is the continents
• the second level is the countries

and our goal to display countries in TaxonomyWebTaggingControl only for selected continent as shown below

This could be achieved by setting AnchorId property for TaxonomyWebTaggingControl control that allows to specify ID of parent Term for any valid value in control.

Implementation

Country picker allows to select continent/country from Countries term set.

Depending on the selected continent  only countries specific  for  continent are shown in TaxonomyWebTaggingControl control

The code below contains Country Picker implementation:
