Hi,
you can just pass an empty collection of columns to dataTable:
private List<IColumn<Contact, String>> columns = new ArrayList<>();
public DataTablePage() {
DataTable<Contact, String> dataTable = new
DefaultDataTable<>("table", columns, dataProvider, 8);
add(....);
}
protected void onConfigure()
{
// modify columns as needed
columns.clear();
if (...) {
columns.add(...);
}
}
In #onConfigure() you adjust the columns as needed for each rendering -
that's all.

Hi Sven,
I'm a bit clueless about this.
Could you share a little code example to help me? Thanks.

Hi,
you can just change the columns list (e.g. in #onConfigure) and
everything will work fine:

Hi all,
I want to render a datatable with dynamically different columns based on
user input (via a DropDownChoice) over ajax.
I came across this old post
<http://apache-wicket.1842946.n4.nabble.com/Dynamic-DataTabl
e-columns-td1856733.html>
which mentions that this feature might be available in Wicket 1.4.
Is this feature available in Wicket now?
Can someone explain me how to achieve this?
