<br>
<b>property</b> Filter: <b>String;</b>
<br>
<br>
<b>Description</b>
<br>
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':
<br>
<br>
State = 'CA' or State = 'MA'
<br>
<br>
When a filter is set, Blank records do not appear unless explicitly included in the filter. For example:
<br>
<br>
State <> 'CA' or State is NULL
<br>
<br>
Filter expressions on remote SQL tables and on client datasets support field comparisons. For example:
<br>
<br>
Field1 > Field2
<br>
<br>
Field comparisons are not supported.
<br>
<br>
The FilterOptions property controls case sensitivity and filtering on partial comparisons.
<br>
<br>
<b>Tip:
<br>
</b> Applications can set Filter at runtime to change the filtering condition for a dataset (for example, in response to user input).
