My Query is How to access Fields on the stacked screen using Screen Object ?
The exact problem is as follows:
I have one screen which has one text field (ClientName) when user clicks on that field , application will then push a new screen and it will allow the user to search in remote database using MyWebSerivces. and when user selects the one client from the search result ,i want to set the text Field on the previous screen with the text that user has selected on the current screen..
i have tried the pushScreen( new screen("text) ) and that might be the result if i want to do this operation only once but this is not the option for me since there is two more such field which will go to other screen to fetch the data from webservices . and if i every time i push new screen then after every pushscreen operation i will only get one field set with the desired text
This not a blackberry (or any specific programming language) related question. This is a question of application architecture and common sense. If one screen should change a Field of another screen, then just pass a reference of the Field to the screen that will change it.
hi i once had same problem and i did like this:
Screen1
------------------
Client Name | text field |
------------------
When user clicks on this text field or any button you push Screen2
In screen 2 when user selects a particular value then u do this.
1) take a static variable in main class say clientName.
2) set value of this variable.
3) pop active screen
UiApplication.getUiApplication().getActiveScreen();
when this code is called then u come back to Screen1
Now in screen1 a method is called
public void onExposed()
{
//here u can set the text in textfield using the static variable
invalidate(); // for repainting
}
i have found the answer to my question. the solution was there lying in my question but at first i was not able to find it.
solution was very simple
when i wrote i want to use
UiApplication.getUiApplication().getActiveScreen()
that was almost the right way and i was proceeding in right direction but the thing that i was missing was " I was not casting the screen (that i have just retrieved form the stack top ) to its type
only thing i should have done is "should have casted screen to its type.like this
UiApplication.getUiApplication().posScreen(this)
(MyScreen1) UiApplication.getUiApplication().getActiveScreen()
now i am able to access all the fields on the retrieved screen (MyScreen1)
things to keep in mind
make sure u cast the screen to its type only otherwise bb will give u resource not found error
Benifits of using screen on Stack
u can use already created screen from the stack no need to create new one
if u will create new screen it will be stacked in memory and will consume more and more memory even if its of no use ( make habit to pop the screen if it is of no use instead of leaving it on stack))
no need to create any static variable since u will be able to set all the field right away from other screen

I want to make two fields always visible on JIRA screens, but not be required.
That way I don't have to open the edit dialog to add story points, but can add/edit/read stories before they're estimated.
How can I make a non-required field always show in a JIRA screen?
You should go to Admin>issues>Field Configuration section. Once here you have to choose your current Scheme and open it.
You will see a screen with all your fields. There are 3 columns, Field name, Screens, and operations.
Go to the field you want to make visible and optional. Set the screens where you want to have it present (i assume that at least you need to add it on "View issue screen", or the custom name you gave it).
Finally make sure that at Operations column, you have correctly set it for been shown (If it allows you the "Show operation" means that it is hidden, and if it shows you "Hide" operation, means that it is gonna be shown)
On the same Field configuration screen, you can make a field Requiered or optional at operations column
I have one edit text in one activity,
I make the text inside it as number and saved that number in shererdPreference.. and make that activity is visible once at the begging of the app, and return to that activity from the setting we made.
How to make that text is visible to user ( fixed ) in edit text?
If the user should not be able to modify the text, use setEnabled(false).
I`m starting in Objective-c this Year and I found nothing that could help me in the logic of how elaborate it:
Look!
I have a UITableView with a list of drugs. When I click on any medication, I'm taken to a DetailViewController that displays the text information about this drug. In this text, I want every time a drug name appear, it appears as if it were a “link”. So when the user clicks, it will be taken to other remedy detailviewcontroller without need to go back to the list of remedies! What is the better way to implement this?
I thought about passing an array with all drugs for DetailTableView controller via Segue, and then conduct a search for any of the remedies present in the text, but i don't know how to turn that word into a link, or set a function to become part of the text (the drug name) clickable
Just to make it clear, let's assume that we are reading the details of the text on the drug called Amoxicillin:
“Amoxicillin drug works better than erythromycin”
What I want is that the name Erythromycin become some kind of link, so when the user clicks on it, is brought to the screen details about erythromycin. Do you guys understand what i mean?
P.S.: I saw that the UITextView has an option called "Links" in attribute inspector, but i have no idea how to use it or if this is for what i want
Thank you all again!!
Use UITextView And select these attribute.
I have 3 grids:- Header,Body and Footer with Body having textboxes.
I have included the Body inside a scrollviewer so that user can type as much data as he wants in the texboxes of Body.
But when the Keyboard pops up the whole view is pushed at top and I cannot see the Header.
The textboxes have wrapping on and also accepts return.
Can the scrollview move up the text when keyboard pops up?
Thanks and Regards,
Kanaya
Not entirely sure if this will help. How about some XAML?
You could capturing the Focus event of the text box that brings the Keyboard up. In that event you could set the scrollViewer.HorizontalOffset property to some caluclated value to get whatever you want in view.
Edit: HorizontalOffest is only a getter user ScrollToHorizontalOffset instead
You probably can make it scroll up like you want, but it will appear very strange to seasoned users of the WP7 operating system. Expected behavior for text input is exactly what you described, the notion Microsoft (I believe) is trying to hit here is that when you want to type something in, you want to clear everything else out of view, and only focus on the textbox at hand.
The form window(chat window) that i am creating for a lan messenger is similar to the one in google talk with two textboxes. What i need to do is to transfer characters typed in the lower textbox(textbox2) to the upper textbox(textbox1 which is read-only) when i click the submit button without showing that textbox1 is read-only because the characters are appearing in grey.please help with code if possible.
Use a label for this instead of a textbox. If the only thing it is doing is display the characters and not a direct edit, you won't lose any functionality and the text would not be greyed out...
If you're going to use a Texbox, set it to Locked. That shouldn't gray the characters out. Otherwise in KeyDown/KeyUp events, set the e.Handled property to true (which will tell the box that you want to handle the input yourself and don't want the message to filter down).
That oughta do it for you.
