rendering panelgrid with ajax primefaces
提问by begiPass
I have this
我有这个
<p:selectOneMenu id="dec" value="#{editCommandController.myCom.decision}" >
<f:selectItems value="#{editCommandController.decisions}" />
<p:ajax update="etat :myform:alors" event="change" />
</p:selectOneMenu>
it allow to disable this
它允许禁用此功能
<p:selectOneMenu id="etat" value="#{editCommandController.myCom.etat}" disabled="#{editCommandController.myCom.decision eq 'rejettée'}" >
<f:selectItems value="#{editCommandController.etats}" />
</p:selectOneMenu>
when the condition is checked and I would like to also hide this panelgrid when the same condition is checked :
当检查条件时，我还想在检查相同条件时隐藏此面板网格：
<h:panelGrid id="alors" rendered="#{editCommandController.myCom.decision ne 'rejettée'}" >
<p:dataTable id="cars" style="width: 80px;" var="car" value="#{editCommandController.pdm}" paginator="true" rows="10"
selection="#{editCommandController.selectedPapier}" selectionMode="single" >
<p:ajax event="rowSelect" listener="#{editCommandController.onRowSelect()}"
update=":myform:jesuis" />
<f:facet name="header">
RadioButton Based Selection
</f:facet>
<p:column headerText="libelle">
#{car.libelle}
</p:column>
<p:column headerText="format">
#{car.format}
</p:column>
<p:column headerText="stock" >
#{car.stock}
</p:column>
</p:dataTable>
<h:outputText id="jesuis" value=" c est la papier : #{editCommandController.selectedPapier.libelle}" />
<h:panelGrid columns="2" cellpadding="5" style="margin-top: 22px;">
<h:outputLabel value="Reliure :" for="city" />
<p:selectOneMenu id="city" value="#{addPapierController.choixReliure}">
<f:selectItem itemLabel="choisir reliure" itemValue="" />
<f:selectItems value="#{addPapierController.libelleReliures}" />
<p:ajax
listener="#{addPapierController.handleCityChange}" />
</p:selectOneMenu>
</h:panelGrid>
</h:panelGrid>
but I notice it check the panelgrid once the panelgrid when the page loads for the first time
但我注意到它会在第一次加载页面时检查 panelgrid
do you any idea to make working this feature for all the time like for selectonemenu above, thanks
你有什么想法让这个功能一直工作，比如上面的 selectonemenu，谢谢

Surround the panelGrid with a p:outputPanel. Then, in the "dec" selectOneMenu, also update the outputPanel. Assuming all these components are inside the same form, it would look like this:
用p:outputPanel.包围 panelGrid 。然后，在“dec”中选择OneMenu，同时更新outputPanel。假设所有这些组件都在同一个表单中，它看起来像这样：
<p:selectOneMenu id="dec" value="#{editCommandController.myCom.decision}" >
<f:selectItems value="#{editCommandController.decisions}" />
<p:ajax update="etat gridContainer :myform:alors" event="change" />
</p:selectOneMenu>
<p:outputPanel id="gridContainer" layout="block" >
<h:panelGrid id="alors" rendered="#{editCommandController.myCom.decision ne 'rejettée'}" >
<!-- panel grid contents here.. -->
</h:panelGrid>
</p:outputPanel>
