Re: Ajax-Panel Toggling Visibility

[Nivedan Nadaraj]

Hi

Thank's for correcting me on how to update the ListView, nicely explained.


1. I am able to view the results panel now.

2. I have made change in the following way to update the list by updating
the model.

Added a WebMarkupContainer and wrapped the ListView within it.
The visibility is applied now only on the WebMarkupContainer that wraps the
list.


So now, I update the model and call
this.setModelObject(updatedModelInstance);,

But now I can see only the header of the Listiview being rendered and the
actual data/repeated items are blank... is not re-painted. The markup on the
ajax response has the following:


*INFO: *Received ajax response (723 characters)
*INFO: *
<?xml version="1.0" encoding="UTF-8"?><ajax-response><component
id="resultListContainer13" ><![CDATA[<div id="resultListContainer13">

<div>
    <table width="0%" cellspacing="0"></table>
    <table width="100%" cellspacing="0" class="dataview">
        <tr>
            <th width="5%">&nbsp;</th>
            <th width="15%">First Name</th>

            <th width="5%">&nbsp;</th>
            <th width="15%"><label for="MiddleName">Middle Name</label></th>

            <th width="5%">&nbsp;</th>
            <th width="15%"><label for="LastName">Last Name</label></th>

            <th width="5%">&nbsp;</th>
            <th width="15%">&nbsp;
            </th>
        </tr>

The content is not rendered, now why would that happen? Does it need to
invoke a method on the result list panel to render the contents? Now am
thinking should i add a wrapper WebMarkupContainer for the PageableListView
as well? So Ajax can re-paint it?

Thanks for the time,
