I have two listboxes in my jsp where in I am dynamically retrieving values for the first listbox based on the previous dropdown selection made by the user. The user will then have an option to move selected values from first listbox to the second. I want to retrieve the values of second listbox in my action class. I tried the following but didn't succeed. Please help...
String[] listbox = request.getParameterValues("ToLB");
Following is my second listbox from which i need to retrieve values,
<select multiple size="8" name="ToLB" style="width:278px;" id="customerListToId"></select>
Solved it by myself.. jQuery worked for the above stated problem..

I have a simple dropdown menu that when an item is selected from another dropdown, it should get populated by a set of values from the database based on the selection value of the second dropdown.
How can I do this in GXT 4?
I've put together an example and posted it to a gist. Would this work for you?

I have a java servlet application where the database is populated by selecting an entry from a dropdown list and entering the values. On another page I have the same dropdown list and also have a find button to display the values that were previously entered by selecting an entry from the dropdown list. I want to get rid of this find button and dynamically display the previously entered values on this page. I heard this can be done using ajax. Please help me out.
Since the code is too much to share I have uploaded the snapshots of both the pages.

Here I am entering the values in estimate by selecting the project

Here I want to get the values just by selecting the project from the drop-down without clicking the Find button
You need to be specific with your question.
If I got you right...
You can use a variable in javasceipt to hold the value that was enterd on the other page you got.
Then while using the dropdown on the other page you can retrieve the values that you store and use a simple ajax request with json data to your servelet.
Check here for examples: http://api.jquery.com/jquery.ajax/
In form I use PageableListView to iterate TextFields. But when I submit form it only validate current page of PageableListView. Also when I back to eg. Page 1 all values I filled disappear.
When I change PageableListView to standard ListView all works fine – validation and submitting.
I set in ListView: setReuseItems(true).
How validate all items in PageableListView?
You can only validate items that are in the form, on the screen. If you wish to validate stuff on the first page, I think you need a (ajax)FormSubmittingBehavior on the paging controls, so your form is submitted each time you navigate to another page.
If you submit the data, it will also be stored if there are no validation errors.
I am trying to filter a list that is placed into a listview through the use of 2 drop down boxes.
The first dropdown box is titled price and the second is owner.
I want to be able to select a value in one or more of these drop down boxes and then have the List view re-render with the filtered results.
The trouble is I do not know how to begin this task, would someone be so kind as to enlighten me :D
Thanks in advance!
Your best starting point is probably this example: (Source code also available on this page, ChoicePage.java is the name)
First of all, you have to use a dynamic model in your ListView that generates the list of items depending on what you had selected in the dropdown boxes.
Then the basic idea is that you add an AjaxFormComponentUpdatingBehavior to the components that control the updates (your two dropdown boxes in your case), and in the onUpdate() method of this behaviour you should add the component you want to update to that AjaxRequestTarget passed.
I have two fields in a webpage. Both are composite primary keys. Out of that when I select one field (eg. out of a list of countries I select - India), the second field should display all the values corresponding to the previous field (eg. after selecting India I should get all the states in another drop-down menu).
I'm implementing this using JSP and Ajax.
Can someone please help me with this or send me the code snippets.?
Neal,
There are various codes available like this. Just do googling.
