Clear af:table filter programmaticallty , reset table filter in 12C (ADF)

Code to reset or clear af:table filter- here searchTabBind is the binding of af:table

    /**
     * method to reset filter attributes on an af:table
     * @param actionEvent event which triggers the method
     */
    public void resetTableFilterAction(ActionEvent actionEvent) {
        FilterableQueryDescriptor queryDescriptor = (FilterableQueryDescriptor) getSearchTabBind().getFilterModel();
        if (queryDescriptor != null && queryDescriptor.getFilterConjunctionCriterion() != null) {
            ConjunctionCriterion cc = queryDescriptor.getFilterConjunctionCriterion();
            List<Criterion> lc = cc.getCriterionList();
            for (Criterion c : lc) {
                if (c instanceof AttributeCriterion) {
                    AttributeCriterion ac = (AttributeCriterion) c;
                    ac.setValue(null);
                }
            }
            getSearchTabBind().queueEvent(new QueryEvent(getSearchTabBind(), queryDescriptor));
        }
    }

use this method on any button or link to clear af:table filter

Apply Filter on af:table column programmatically ,Invoke 'FilterableQueryDescriptor' through managed bean

Hello All
This tutorial is about a requirement of filtering af:table column through code,
to achieve this we can invoke FilterableQueryDescriptor (FilterableQueryDescriptor is an abstract subclass of QueryDescriptor. It adds support for filtering of data and is typically used by the table component to filter data from a query )

Suppose i have department table and i have to filter on department column-

• Create a Fusion Web Application and business components for Departments (HR Schema) table
• now drag table on page and bind it to bean

• Now drop a input text and button on page to enter Department Name
• bind input text to bean and create ActionListener on button to filter Department Table
