Re: [Wicket-user] Dropdown choices in wicket
First of all, let me tell you that, I am also fairly new to Wicket. However here are my two cents. Wicket experts - Please correct me if I am wrong. How are you sending the data to the page? Are you using any model? If you are, you can retrieve the data using the model object. If not, I think you can use PageParameters to retrieve the selections from the select box just like any other component on the page. For hidden fields, I think you can use regular Textfield and set the visible (setVisible) to false. This way you have all the access to the field except that it won't be displayed on the screen. Hope this helps. -Srinu - Original Message From: sathya81 [EMAIL PROTECTED]To: wicket-user@lists.sourceforge.netSent: Friday, August 18, 2006 12:02:46 AMSubject: [Wicket-user] Dropdown choices in wicket Hi, iam new to wicket, am going through the available examples, i dontunderstandhow can i capture the selected option in a drop down choice inthe wicket?

Re: [Wicket-user] Dropdown choices in wicket
About the dropdown: Use a model, maybe a property model to hold the selected dropdown object. Property models require that there are a get and setter method for the supplied property. You could also use the abstractmodel and implement your own thing, if per say you needed to update something else on the page based on what the selected dropdown are. Just to sum it up, wicket does all the nifty stuff about updating the model that you provide so you need only do your logic. Please ask if you have more questions. regards Nino -Oprindelig meddelelse- Fra: [EMAIL PROTECTED] på vegne af sathya81 Sendt: fr 18-08-2006 09:02 Til: wicket-user@lists.sourceforge.net Cc: Emne: [Wicket-user] Dropdown choices in wicket Hi, iam new to wicket, am going through the available examples, i dont understand how can i capture the selected option in a drop down choice in the wicket?

As well as what the others have said, take a look at the wiki, specifically http://www.wicket-wiki.org.uk/wiki/index.php/DropDownChoice_Examples, which might help. /Gwyn On 18/08/06, sathya81 [EMAIL PROTECTED] wrote: Hi, iam new to wicket, am going through the available examples, i dont understand how can i capture the selected option in a drop down choice in the wicket?

Re: [Wicket-user] Dropdown choices in wicket
Select/Combo is just as another input field. The model behind the Combobox will hold the selected value.Hidden field: See HiddenField componentBut the question is why do you need it? Normally in wicket there is no need for a hidden field to store data. johanOn 8/18/06, sathya81 [EMAIL PROTECTED] wrote: Hi, iam new to wicket, am going through the available examples, i dontunderstandhow can i capture the selected option in a drop down choice inthe wicket?

Re: [Wicket-user] Dropdown choices in wicket
Hi Sathya
Yes you should use one model for each of your dropdowns.
Lets say you are creating a site where you can search for books.
Then you might have a drop down for author and maybe category.
I guess(without knowing anything about searching and or books:)) that I would
create a class that holds the search criteria eg:
search.java
private author
private category
getter setter methods goes here
so on my wicket page i'll have the following pseudo code:
private Search bookSearch=new Search;
Imodel author=new Propertymodel(bookSearch.author,search);
Imodel category=new Propertymodel(BookSearchcategory,search);
dropdown dropAuthor=new dropdown(id, author);
add(drop)
dropdown dropCat=new dropdown(id,category);
add(drop)
button search=new Button(id){onsubmit(
process(search))
}
add(search)
I hope my simple example contributes to something usefull:)

Re: [Wicket-user] Dropdown choices in wicket
Hmm - should isn't really correct - could, yes, but not should.
Personally, I'd suggest a single CompondPropertyModel, set for the
form, if not the page, as that can really cut down on the code you
need to write.
That also solves where to put any associated data, as the ModelObject
that the CPM wraps isn't restricted to /just/ the form data. No need
for 'hidden' client-side properties!

true, I was meerly trying to explain that you really dont have to grab the
