Specifies the text of the current filter for a dataset.
property Filter: String;
Use Filter to specify a dataset filter. When filtering is applied to a dataset, only those records that meet a filter's conditions are available to an application. Filter contains a string describing the filter condition. For example, the following filter condition displays only those records where the State field is 'CA' or 'MA':
State = 'CA' or State = 'MA'
When a filter is set, Blank records do not appear unless explicitly included in the filter. For example:
State <> 'CA' or State is NULL
Filter expressions on remote SQL tables and on client datasets support field comparisons. For example:
Field1 > Field2
Field comparisons are not supported.
The FilterOptions property controls case sensitivity and filtering on partial comparisons.
Applications can set Filter at runtime to change the filtering condition for a dataset (for example, in response to user input).
