How to hide / show additional descriptive Row below empty DataView?
Hi all,
How is it possible to dynamically show and hide an additional dummy
row "No items to show" below a DataView?
I tried this with code similar to code below but it does not work even
though isVisible() is called. I have a small testcase ready to go.
It's quite basic so I must be missing something obvious.
Many thanks
Bernard
In a DataView, with an AjaxFallbackLink delete action, in onClick I do
something like
item.setVisible(false);
target.addComponent(item);
target.addComponent(emptyRow);
with emptyRow as follows:
final WebMarkupContainer emptyRow = new
WebMarkupContainer("emptyRow"){
@Override
public boolean isVisible(){
return rowProvider.size() == 0;
}
};
emptyRow.setOutputMarkupId(true);
add(emptyRow);
In HTML:
<tr wicket:id="dataRow">
<td wicket:id="Id">ID</td>
<td><a wicket:id="delete">Delete</a></td>
</tr>
<tr wicket:id="emptyRow">
<td colspan="2">No Items to show</td>
</tr>

two suggestions,
1)emptyrow.setoutputmarkupplaceholdertag(true) instead of
setoutputmarkupid(true).
2)you can use dataview.getitemscount() instead of data.size() as later can
be expensive.
