Inject CSS styles into panelgrid on-the-fly

How can I pass a color code property fetched from ebean to a css function?

    <h:panelGrid id="testpanel"
       columns="#{message.no_of_columns}" rows="#{message.no_of_rows}" 
      styleClass="dynamicGrid">
     <c:forEach items="#{bLDashBoardAction.listBondLoc}" var="item">
      <h:panelGroup>                                                 <h:outputText value="#{item.rackTagCode}" />
   <h:hiddenInput value="#{item.colorEBean.colorCode};" />
                                            </h:panelGroup>
</c:forEach>
</h:panelGrid>

I need to assign the background from panelgrid color code using this css property.

.dynamicGrid td
{
width: 50px;
height: 50px;
border: 4px solid gray;
    background:

}

Answer №1

Due to the limitations of the unusual design, your best option is to directly apply the style to the cell's content.

<h:outputText value="#{item.rackTagCode}" style="display:block;color:#{item.colorEBean.colorCode};" />

The display:block property will cause it to fill the entire cell.

Answer №2

If you're switching from JSF to CSS, don't assume it's a seamless transition. Instead of trying to manipulate CSS directly, consider creating specific classes with designated background colors - for example, .dynamicGridRed and .dynamicGridYellow.

You can then use these classes conditionally by calling them like this:

styleClass="#{item.colorEBean.colorCode}"
, where colorCode could return either dynamicGridRed or dynamicGridYellow.

Another approach is using inline CSS, such as:

styleClass="#{item.colorEBean.useRedCode?'dynamicGridRed':'dynamicGridYellow'}"

Instead of attempting to modify the CSS content itself, consider sticking to predefined CSS classes. It's generally more efficient than trying to manipulate CSS properties on the fly.

Keep in mind that I'm not a CSS expert, so take my advice with a grain of salt.
