We have 2 select elements in a web page. The options in 1 are dependent on the selections made in the other. When the user changes a selection in the 1st drop down via the UIPicker the resultant changes in the 2nd drop down are not reflected in the picker. We have close the picker and reopen it to see the changes. Is it possible to force the picker to refresh from the web page?

In my eclipse application when more than 3 views are open, I need a drop down as shown in picture clicking on which gives me the list of rest of the views.
I have experience in Android and currently started to learn iOS. I created a mechanism to Pick data in an Android App. When I click on Date button, a DatePicker pops up:
As you see It has Cancel and Set button.
My question is about my iphone App. I want to have the same mechanism. When I click on the button, Date picker pops up (that can have Set and cancel button like Android Date picker). How can I do that? I'm not sure that it is a good way in iPhone, Can you help me if we can design a better mechanism?
Here's a UX comparison between Android and iOS standard widgets, with links to the documentation on the relevant Apple / Android websites. It's a nice way to get started learning all the technical terms.

Hopefully that gets you started.
Apple has a sample project that demonstrates this. You'll have to adapt it slightly: instead of showing/hiding the date picker itself, you'll want to show/hide a view containing a date picker and a dismissal button.
It's called DateCell.
Basically, it treats the date picker as if it were the keyboard for a cell containing the date. You'll need to manage hiding it when the user enters a text field (and thus, needs the real keyboard) and scrolling to keep the date row in view, but all the bits you need are in this project one way or the other.
One way to do it would be add a custom buttons to the same view containing date picker and then pop it up when the users wants. Instead of using the date picker delegate use the buttons action to get the date picker value.
I’m using JFace viewer Framework in my eclipse rcp application, I’ve created a Table Viewer, which populates some data .My view has a refresh button below tableviewer, when I select a row in tableviewer and trigger refresh button the selected row still appears in gray color.
Scenario is depicted below
Before selecting a row
After selecting a row
After refresh
In what way can i remove the gray background as in the above figure and make it as 1st image.
My refresh button listener code is simple which has
viewer.refresh();
as a workaround i tried implementing methods like
viewer.getTable().redraw();
viewer.getTable().setRedraw(true);
which doesn't work, is there a solution to refresh it or should I refresh the view totally
Note: My Execution environment is windows xp
That gray line is current, not previous selection. It's gray because table is not in focus. Use setSelection(StructuredSelection.EMPTY).
If you create the table with the style flag SWT.HIDE_SELECTION the table will not show its selection when it loses focus. I.e. it will look like your first image.
I'm creating an app and I need some help with design.
Launch Screen - I want to show 6-8 "category" buttons with labels loaded from an array ("normal" buttons from interface builder - not tab bar buttons or menu bar buttons).
Table Screen - When one of the category buttons is pushed on the launch screen, I want to show a table view with all of the items in that category.
Detail Screen - When one of the items on the table screen is selected, go to a new screen with details for the item. There will be an action button on this screen which will remove the item from the list if pressed.
My questions are as follows:
1) I don't want to show navigation buttons on the first screen. Can I still use a Navigation-Based application and hide the navigation controls on the first screen, or would it be better (easier) to create a view-based application and put a navigation controller "inside" one of the views? I'm totally open to any basic design approach suggestions you may have.
2) I've figured out how to create a sqlite3 file, add it to the project, query it, and generate the table view from the results, but I'm not sure about how to store the sqlite file in a way that will persist on the device when the user upgrades the app later. Any pointers on that?
Thanks for any help/links/documentation you can point me to. I've watched a million tutorials but none of the ones I've seen really address basic app design.
Now for Q1, both ways work fine but if you have buttons from the first screen, having a uinavigationcontroller might make it slightly easier if you plan to have back buttons on the screens after the first screen.
For Q2, to make the database persist when the user updates their app at some stage, simply keep the original database and include a new database (with a different name) with additional content, then modify your original database and import any additional content to it.
You can also do variations of that also, ie import content from old database to new database and etc. But the key is to keep the database file names different, ie add database_v1.sqlite, database_v2.sqlite and etc.
BTW don't forget to clean up any databases you won't use in future.
I've added a FilterForm with GoAndClear buttons to an AjaxFallbackDefaultDataTable. The filtering is working fine except for refreshing my table. I have a dropdown that changes the number of rows to show which does a target.addComponent(my AjaxFallbackDefaultDataTable) which doesn't reload the data but refreshes the. If I use this after I click a Go or Clear button then the table shows the proper rows, item count, and page links.
How can I handle Go and Clear clicks on my FilterForm to update my AjaxFallbackDefaultDataTable?
In the onsubmit method for the filter form just call .renderComponent() for the table.
