Send Ajax request to refresh dataTable

[naveen gupta]

I have a dropdown and a dataTable in the page

everytime i change value in the dropdown, i have to hide dataTable in the page, which is NOT working

what i observed is that change in the value for drop down, i can send ajax request only to hide and display individual components like textbox

what it's not working for the dataTable

It MIGHT work(i am not sure, still haven't tried), if i use a4jutputPanel, but if i use this one then for every ajax request in that page refreshes the dataTable, which i don't want

What it sounds like you should be doing is updating the datatable based upon the selection
from the menu, i.e. select Department A, get list of employees from department A. I don't
get the show/hide thing, this sounds like a javascript hangover.

Do something like this:

<h:dataTable id="table1">
...
</h:dataTable>

...

<h:selectOneMenu value-...>
  <f:ajax render="table1"/>
</h:selectOneMenu>

Try this.

after selecting the value from dropdown, i will click on "Search" button to show the list in dataTable
I am displaying the results only after clicking on the search button and not after selecting the value in drop down


What i want to do is send ajax request based on the change of value selected from dropdown
and the ajax request basically hides the dataTable

Brendan, you understood correctly

But your solution is not working for me ( i am using RichFaces for your information )

it resolved. Following is the code

<a4jutputPanel id="dataRegion" ajaxRendered="true" >
<rich:panel rendered="#{rTestBean.pclist}">

</rich:panel>
</a4JutputPanel>


The mistake i was doing was

<a4jutputPanel id="dataRegion" ajaxRendered="true" rendered="#{rTestBean.pclist}">
<rich:panel >

</rich:panel>
</a4JutputPanel>

[I wasn't correct as it turns out - the last reply wasn't there when I typed this in]

Ok, I think I know what the problem is:

<h:dataTable id="table1">
...
</h:dataTable>

<h:selectOneMenu id="smenu" value-...>
  <f:ajax render="table1"/>
</h:selectOneMenu>

<h:commandButton action=...>
  <f:ajax execute="smenu" render="table1"/>
</h:commandButton>

You are not including execute= for the selectOneMenu, am I correct?
This is only a guess as you've not posted any code.
