	rowStyleResolvers

...

(Grid's) Row style resolvers returns set of CSS clas names for given row entity. You can use them to mark specified grid rows, e.g. whith negative balance of some arbitrary values.
Resolver method is invoked for each of row entity.

...

CSS class name	Constant	Description
redBg	RowStyle.RED_BACKGROUND	set row background to red
boldFont	RowStyle.BOLD_FONT	set row font weight to bold

Info
Prefer constants over CSS class name literals. This will help you avoid many mistakes and keep your code easier to maintain.

Info
You can also create infinity number of your own, custom row styles - see Customizing GUI appearance section.

To see how to bind created resolver method with view component go to 'row style resolvers' section.

If you need some sample code see Row style resolver example in Examples section.

2.6. Criteria modifier

(Grid's) Criteria modifier allow you to modify state of the SearchCriteriaBuilder used by view component to fetch row entities.

Code Block

theme	Eclipse
language	java
linenumbers	true

public void criteriaModifierName(final SearchCriteriaBuilder searchCriteriaBuilder) {

        // CRITERIA MODIFIER BODY

}

Where

criteriaModifierName - arbitrary name of modifier method
searchCriteriaBuilder - criteria builder used by component

There is also second version of criteria modifier method that you can define:

Code Block

theme	Eclipse
language	java
linenumbers	true

public void criteriaModifierName(final SearchCriteriaBuilder searchCriteriaBuilder, final FilterValueHolder filterValueHolder ) {

        // CRITERIA MODIFIER BODY
}

Where

criteriaModifierName - arbitrary name of modifier method
searchCriteriaBuilder - criteria builder used by component
filterValueHolder - criteria value passed from before render hook.

To set FilterValueHolder you have to get it from LookupComponent in before render hook, modify it and set it again

Code Block

theme	Eclipse
language	java
linenumbers	true

public void beforeRenderHook(final ViewDefinitionState viewDefinitionState) {
	LookupComponent lookup= (LookupComponent) 
					viewDefinitionState.getComponentByReference("lookupReference");
	FilterValueHolder holder = lookup.getFilterValue();
	holder.put("key", "value");
	lookup.setFilterValue(holder);
}

To see how to bind modifier method with view component go to 'criteria modifiers' in 'Hook an Listeners' section.

If you need some sample code see Criteria modifier example in Examples section.
