How to Hide/View Fields at run time combo selection
Hi,
I have combo box with 3 items, String, Number, Date
If I select String, Maximum character label with one textbox should display.
some code :
Initially I have hide Maximum character label and textbox using
setVisible(false);
In AjaxFormComponentUpdatingBehavior("onchange"), protected void
onUpdate(AjaxRequestTarget target)
inside this method,
I wrote:
maxLength.setVisible(true);
target.addComponent(maxLength);
setOutputMarkupId(true);
But in onchange combo, that text box not displaying.... When I click the
same page tabs, that textbox is displaying.
Please send your suggestions.
Thanking You,
Regards
Edi

The label must be inside of a WebMarkupContainer (which will always be
visible), because if the label is not rendered at the first render
then wicket will not find the markup when you try to change the
visibility to true.
And of course your target.addComponent must add the container, not the label.

if you want to initially hide components and show them later via ajax,
you have to call .setOutputMarkupPlaceHolderTrag(true) for the component.
