I am looking to apply unique CSS classes to certain rows within my <h:dataTable>. Is it possible to manipulate and style the individual table rows in a customized manner?
I am looking to apply unique CSS classes to certain rows within my <h:dataTable>. Is it possible to manipulate and style the individual table rows in a customized manner?
Connect the rowClasses property to a bean method that generates the necessary CSS classes.
<h:dataTable value="#{bean.list}" rowClasses="#{bean.rowClasses}">
For example, you can achieve this by:
public String getRowClasses() {
StringBuilder rowClasses = new StringBuilder();
for (Item item : list) {
if (rowClasses.length() > 0) rowClasses.append(",");
rowClasses.append(item.getRowClass());
}
return rowClasses.toString();
}
Update to clarify, with this approach you have complete control over the generated rowClasses string. The provided example is just a starting point and doesn't have to rely on Item#getRowClass(). You could use a simple loop with a counter instead.
For instance:
public String getRowClasses() {
StringBuilder rowClasses = new StringBuilder();
for (int i = 0; i < list.size(); i++) {
if (rowClasses.length() > 0) rowClasses.append(",");
rowClasses.append(selected.contains(i) ? "selected" : "none");
}
return rowClasses.toString();
}
Here, selected is a List<Integer>. If it includes values like 1, 2, and 5, then the resulting string will represent each of the 10 items with either "selected" or "none" classes:
none,selected,selected,none,none,selected,none,none,none,none
I think @BalusC has a great suggestion. For another option, you could easily achieve this using JavaScript and jQuery.
If you're using jQuery, it can be done like this:
(Please note that this is just a sample code and may need refinement)
$(document).ready(function(){
var counter = 0;
$('#myTable').each(function() {
counter = counter + 1;
if(counter==3) {
$(this).addClass('redRow');
return;
}
});
}
