Question

I have this datatable that loadied from the datatabase, here is :

<p:dataTable id="cars" var="car" value="#{acceuilUserController.lc_maj}" tableStyle="width:auto">  
 <p:column headerText="Commande N° : " style="width:100px">  
 <h:outputText value="#{car.commande.id}" />  
 </p:column>  
 <p:column headerText="Date de mise à jour : " style="width:100px">  
 <h:outputText value="#{car.dateMaj}" />  
 </p:column> 
 <p:column headerText="Decision : " style="width:100px">  
 <h:outputText value="#{car.decison}" />  
 </p:column>

 </p:column> 
</p:dataTable>    

I have another attribut car.lu that accept two values :true or false, I want when it is false the line flashes and become colored with red
how I can achieve this?

Answer 1

You can achieve this using conditional coloring:

<p:dataTable id="cars" var="car" value="#{acceuilUserController.lc_maj}" tableStyle="width:auto" rowStyleClass=#{(car.lu == false) ? 'red' : null}>
    <p:column headerText="Commande N° : " style="width:100px">
        <h:outputText value="#{car.commande.id}" />
    </p:column>

    <p:column headerText="Date de mise à jour : " style="width:100px">
        <h:outputText value="#{car.dateMaj}" />
    </p:column>

    <p:column headerText="Decision : " style="width:100px">
        <h:outputText value="#{car.decison}" />
    </p:column>

    <p:column headerText="Etat : " style="width:100px">
        <h:outputText value="#{car.etat}" />
    </p:column>
</p:dataTable>

If car.lu returns false the style class red is applied to the row. So you have to have this in your CSS:

.red {
    background-color: red;
}
