addMark

allows setting custom flag for a data item.

id	string	the id of a data item to mark
name	string	the flag name
css	boolean	if set to true, the css style with the name equal to the name parameter value will be applied to the marked item
value	any	the value of the flag
silent	boolean	(optional) if set to true, the component is not redrawn

any	the flag value

Example

//adds flag 'invaid = true' for the item with 'id=2'. 
//applies to this item css style ".invalid" 
 
$$("dtable").addMark(2, "invalid", true, true); // returns 'true'

The method adds some info (as a key/value pair) related to a data item, marking the item thereby. The added information is stored separately from main data. So if you, for example, load data from one data store to multiple components, the mark will exist just for a data item of the calling component.

The method can be called in 4 ways:

1. addMark(id, name) //-> 'css' is set to false, 'value' - to true
2. addMark(id, name, css) //-> 'value' is set to true
3. addMark(id, name, css, value)
4. addMark(id, name, css, value, silent) //-> 'silent' is set to true, do not refresh the component
