Property Value

If this property is not set, all features within the current map extent will display map tips (up to the limit set in FeatureLimit).

Set this property to limit maptips to features that match the where clause filter. Be careful that the where clause is valid for the layer. If not valid, no error will occur, but no maptips will be displayed. The where clause must be a standard query, and fields must be present in the layer. Values are case sensitive. Some examples of where clauses:

• POPULATION > 10000
• CAPITAL = 'Y'
• NAME like 'A%'

The final example displays only features whose NAME field begins with the upper-case letter A.

One way to create a valid where clause is to add (at least temporarily) a QueryAttributesTask to the page, and to use its query-builder utility to construct the where clause.
