[英]Update component at change of page on primefaces datagrid with pagination
I have a datagrid with pagination. 我有一个带分页的数据网格。 When I change the page I want to update some components in the page, but I don't know how to get the event.
当我更改页面时,我想更新页面中的某些组件,但我不知道如何获取该事件。 Some code:
一些代码:
<p:panelGrid id="buttons">
<p:commandLink value="Link1" action="#{myBean.method1}" disabled="#{myBean.boolean1}" />
<p:commandLink value="Link2" action="#{myBean.method2}" disabled="#{myBean.boolean2}" />
</p:panelGrid>
<p:dataGrid var="myVar" paginator="true" value="#{myBean.listOfObjects}">
...
...
</p:dataGrid>
I want something like update="buttons"
in the dataGrid, so when the page changes, update the buttons depending on disabled=""
attribute of the buttons, is it possible? 我想在dataGrid中使用类似
update="buttons"
东西,所以当页面改变时,根据按钮的disabled=""
属性更新按钮,是否可能?
Greetings. 问候。
Finally, instead of <p:dataGrid ... />
i used <p:dataTable ... />
with <p:ajax ... />
inside, this is my code: 最后,我使用
<p:dataTable ... />
和<p:ajax ... />
代替<p:dataGrid ... />
,这是我的代码:
<p:dataTable var="myVar" paginator="true" rows="1" value="#{myBean.listOfObjects}">
<p:ajax event="page" update="buttons" listener="#{myBean.update}" />
...
...
</p:dataTable>
And update
method: 并
update
方法:
public void update(PageEvent event) {
int var = event.getPage();
...
(update components values of dataTable and buttons using var)
...
}
