Advice re: view states

Hi. I created an app that works a bit like a calculator to calculate expenses. As part of the app the user can click on a question mark which brings up an information section - a bit like a "pop-up" - with the original calculator screen still in the background...if i was using Flash I could just keep this "pop-up" on the edge of the stage and then tween it in to view when the user clicks the question mark...i've read up on view states but not sure if this is appropriate for what i want or if there is a better way to do this in flex.
thx.

For complex views, you will find ViewStack much easier and
more intuitive to code.
But that won't solve your problem. The best solution to this
is to simply reload the application using navigateToUrl().

Controlling view states

It would be nice to get feedback from a more experienced
developer about how I should implement my view with regards to
state, on the one hand I have a book (essential flex 2.0 with
actionscript 3.0) which explains that view state should be handled
using <mx:state> and on the other hand I have the cairngorm
examples (cairngorm store and cairngorm login) that use a
viewstack.
I don't think I fully comprehend what the implications of
choosing one or the other will be, other than using viewstack looks
simpler.
I would be grateful for any advice. Thankyou

from flexcoders on yahoo
Here's what I'm getting from all the manual reading I've been
doing over the past week. Others may correct me or clarify as
needed.
- Think of the base state as the "home page"... it's the
initial state of the app or component when the user browses to it.
I can't think of a good reason why it would ever be empty unless
you wanted to implement some kind of transition or effect
immediately upon loading it.
- In the larger sense of UI design, HTML "pages" are
addressed in the Flex metaphor with ViewStacks attached to a
navigator. Use this for macro changes in the interface.
- View states are used to display incremental changes in
state. Sounds like you are using that correctly insofar as you
describe it... however, depending on how your user interface is
designed and what you're trying to accomplish, the "Detail" state
you describe could also be just an incremental change to the
"Master" state with the Master state remaining visible. Also, the
"Master" state could be your base state since it's empty and that's
the first thing the user sees.

View State Animations & the Back button (on Android)

Hello, everyone!
Is it possible to animate between view states when developing for mobile devices (like Android)?
And if so (and the bigger question for me), when you transition from one state to another, can you use the Back button on the Android device to transition back to a previous state?

Hi, Jason,
First and foremost, thank you for your timely response, and for your well-received advice!
After reading the posts from the MAX Beta link your provided, it is my understanding that if you disable the default back button handling, that the button itself would no longer function in the application.
I still want to use the back button, but I want to add the back button's popView function to states as well as Views.
If I missed anything, please let me know.
And thank you, once again!
PS-I don't know if this makes a huge difference, but I'm using the latest pre-released version of Flash Builder 4.5 with AIR 2.6 (released 2 weeks ago).

C#/SharePoint -View State related issue while exporting data to excel

We have web application based on SharePoint. We have a list view to display data based on Search Criteria. We have total of around 16000 data. When we try to export all data to excel it gives an error. The cause of the issue is:
View State is used to save the state of page i.e. the previous state. When the export to excel link is clicked, the data present in the grid is actually saved in view state so that the overhead of again generating
the data(as per the selection criteria) can be avoided. Now, this View state has a limitation of storage of these records. When we put in some selection criteria, the no. of records is less hence no problem in actually storing the view state. But when there
is no selection criteria, 16306 records are too much to be stored in view state. Hence the error occurs.
We tried to solve this issue by creating a compressor class and overriding two methods:
LoadPageStateFromPersistenceMedium
SavePageStateToPersistenceMedium
This has resolved the issue with Export to Excel. However, there is now some issue in the paging of the list view. The list view has a column with hyperlink which opens related data in a form. While we click on the link in 2nd
page of the list view, it displays data for the link in the 1st page at same row.
Please suggest how to resolve this issue or any workaround for this

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

Flex 3 :Help needed in implementing View States

Hi
I am new to Flex , i am trying to understand View States , tried for one hour but got confused .
(Basically by seeing the examples i understood the concept , but failed to implement )
Please help .
Assume my requirement is at the load of the page , i want to show an Login Button and a Chnage State Button (common button) only .and when the Change State button is clicked on ,i want to show the Register Button .
So for this i made two Forms , and a common button .
 <mx:Form id="RegForm">
 <mx:Button label="RegFormButton" id="RegFormButton"/>
 </mx:Form>
 <mx:Form id="loginForm">
 <mx:Button label="LoginButton" id="loginButton"/>

Populate Flex Grids during view state?

Hi, I am very new to Flex. I am working on a Flex project where I want to populate xml data in the two grids during viewstate. In my project, I have two grid which resides in the two discinct view state named as "Category" and "Topic". For these two view state, i have two disctinct grids.

SSRS 2012 Problem understanding View State Validation steps

Hi,
***** Note I have put my question on Bold to make it easier****
I am trying to Implement this solution on our systems and need help on how to set it up ?

How to Configure View State Validation
To run a scale-out deployment on an NLB cluster, you must configure view state validation so that users can view interactive HTML reports. You must do this for the report server and for Report Manager.
View state validation is controlled by the ASP.NET. By default, view state validation is enabled and uses the identity of the Web service to perform the validation. However, in an NLB cluster scenario, there are multiple service instances and web service
identities that run on different computers. Because the service identity varies for each node, you cannot rely on a single process identity to perform the validation.
To work around this issue, you can generate an arbitrary validation key to support view state validation, and then manually configure each report server node to use the same key. You can use any randomly generated hexadecimal sequence. The validation algorithm
(such as SHA1) determines how long the hexadecimal sequence must be.
1.
Generate a validation key and decryption key by using the autogenerate functionality provided by the .NET Framework.(Well, how to generate Validation key using .Net Framework?)
In the end, you must have a single <machineKey> entry that you can paste into the Web.config file for each Report Manager instance in the scale-out deployment.
The following example provides an illustration of the value you must obtain. Do not copy the example into your configuration files; the key values are not valid.
Copy Code
<machineKey validationKey="123455555" decryptionKey="678999999" validation="SHA1" decryption="AES"/>
2.
Open the Web.config file for Report Manager, and in the <system.web> section paste the <machineKey> element that you generated. By default, the Report Manager Web.config file is located in \Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting
Services\ReportManager\Web.config.
3.
Save the file.
4.
Repeat the previous step for each report server in the scale-out deployment.
5.
Verify that all Web.Config files in the \Reporting Services\Report Manager folders contain identical <machineKey> elements in the <system.web>
Does the key generate using above generates the key with same element ?
Any help on this would be appreciated .
Thank you !
Thanks

Hi SQL_Help:
Per my understanding that you have some question with the steps descript about "How to Configure View State Validation", you don't know how to generate Validation key and also not clear if all the Web.Config files will add the same
code, right?
We have many method to generate the validation key,details information below for your reference:
Generate either from the machineKey generator utility from
http://aspnetresources.com/tools/keycreator.aspx or your very own utility or from this link: http://www.eggheadcafe.com/articles/GenerateMachineKey/GenerateMachineKey.aspx
We can add some code to generate the key, details steps and sample code in article below for your reference:
How to create keys by using Visual C# .NET for use in Forms authentication
We should add the same code which include the generated key in all the web.config file in each server node.
More Details information you can reference to the rticle below:

Hi Arun,
 The word Form misleads you i think so its not Form. Jspx only.
 I have created a small sample application using HR database.
 Created CountriesEO using countries table.
 Created Countries.jspx, in that created one filterable table using CountriesVO.
 Run the Countries.jspx page is rendered on the Browser.
 Now if I do any change say for Ex: Given editingMode="editAll" to the Table Save and
 now come to the page already Running on the Browser and applied Filter for
 Country Name column this Error comes.
 1. Are you running the App in Debug mode? -- In Both Run & Debug Modes it comes.
 2. Is there any backing bean for the jspx page? -- no backing Bean created.

Change base view state from a custom component

I'm pretty new to flex and I'm having a small issue in change the view state from a component.
My Application have 2 custom components called userlogin and main menu. In the main application page I have userlogin component in one state and the main menu component in another. I'm trying to change the state if the login in successful from user login to main menu. I have the following function written inside the login component.
private function IsUserLoggedIn(evt:ResultEvent):void
                if (evt.result.islogin.toString() == "true")
                    currentState = "MainMenu";
                else
                    Alert.show("Login failed, please try again.", "Login Failed");
This code worked when I had all the controls in the main page. But then I created components and included them in to components and now when the login is success, its giving the following error.
ArgumentError: Undefined state 'MainMenu'.
    at mx.core::UIComponent/getState()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UI Component.as:9908]
    at mx.core::UIComponent/findCommonBaseState()[E:\dev\4.0.0\frameworks\projects\framework\src \mx\core\UIComponent.as:9928]

    at components::UserLoginForm/__btnSubmit_click()[C:\Projects\WarrantyAutomation\src\componen ts\UserLoginForm.mxml:60]
I'm sure this has something to do with accessing the states from a custom component, but I do not know how to change the state to the main menu. Please help me with this. Any help is greatly appriciated.

Hi dasun1981,
private function IsUserLoggedIn(evt:ResultEvent):void
                if (evt.result.islogin.toString() == "true")
                    currentState = "MainMenu";
                else
                    Alert.show("Login failed, please try again.", "Login Failed");
If I am right the above function is in your userlogin component and the two components "userlogincomponent" and "maincomponent" are in main application file and the states were also defined in main application file.
But in the function above the currentState refers to the state of the userlogin component and not the main application ...but the states are defined in main application file...that's the reason why the exception was thrown...
Instead you replace the line in the above function with the below line:
Application.application.currentState = "MainMenu";
Please mark it as answer if it helped you.
Thanks,

If I run every line but the create (just execute the query) it runs fine. It also works fine in a PL/SQL procedure.SQL*Plus abhors a vacuum.
The default in SQL*Plus is that you can not have a completely blank line (that is, a line containing only white space) in the middle of a SQL statement. (Blank lines are okay in PL/SQL, including SQL statements embedded in PL/SQL.)
If you want some space between the end of the WITH clause and the beginning of the main query (or anywhere else, for that matter), you can put comments there. For example:
      ORDER BY T0.CARRIER_SHORT_NAME)
     select *
       from carriers c;Now that line isn't just whitespace; it has the comment sign, and that's enough for SQL*Plus.
You can allow completely blank lines with the SQL*Plus command:
SET   SQLBLANKLINES ON

Reload data when chaning view state

Hi all,
I have a main application ("MTF.mxml") and two view states in
the application (myChallenges) and (responses). In the view states,
I have inserted two customized components.
The MyChallenges-component is a list of challenges and when a
challenge is selected, I switch from the myChallenges-view state to
the responses-view state using a costum event dispatcher.
So far so good,
The problem is that when I change to the responses-view state
and therefore to my responses-component, the data loading on the
panel of the component is only the request that I get when I for
the first time enter the responses-component. When I go forward in
my application from the responses-view state to the
myChallenges-viewstate to pick a new challenge, the responses-view
state does not reload with the new challenge id - actually, no
action script code in the responses-component is processed at all!
I figure it has something to do with the component's loading
events.
I use the creationComplete-tag property in the component to
activate an init()-function to handle my ActionScript code. But
this seems to activate the function only when the component is
created for the first time!
How do I handle this? I tried using the enterState-property,
but with no succes!
Please help me, if anyone knows the answer!

Thank you for the quick feedback.
The enterState-property works fine, it seems that the Action
Script code loads every time.
Actually, what I really wish is that the component "reloads"
every time. The problem is that my actionscript code adds elements
to the scene, edits properties and so forth, everything depending
on what challengeId there is given to the component. When the
component has completed the code once, variable-values, elements
and so forth are still kept until the state is entered again. Is it
not possible to actually reload the component - not just making
"show/hide" it, as I do now?

How to Configure View State Validation
To run a scale-out deployment on an NLB cluster, you must configure view state validation so that users can view interactive HTML reports. You must do this for the report server and for Report Manager.
View state validation is controlled by the ASP.NET. By default, view state validation is enabled and uses the identity of the Web service to perform the validation. However, in an NLB cluster scenario, there are multiple service instances
and web service identities that run on different computers. Because the service identity varies for each node, you cannot rely on a single process identity to perform the validation.
To work around this issue, you can generate an arbitrary validation key to support view state validation, and then manually configure each report server node to use the same key. You can use any randomly generated hexadecimal sequence.
The validation algorithm (such as SHA1) determines how long the hexadecimal sequence must be.
Generate a validation key and decryption key by using the autogenerate functionality provided by the .NET Framework.
(Well, how to generate Validation key using .Net Framework?) In the end, you must have a single <machineKey> entry that you can
paste into the Web.config file for each Report Manager instance in the scale-out deployment.
The following example provides an illustration of the value you must obtain. Do not copy the example into your configuration files; the key values are not valid.
Copy Code
<machineKey validationKey="123455555" decryptionKey="678999999" validation="SHA1" decryption="AES"/>
Open the Web.config file for Report Manager, and in the <system.web> section paste the <machineKey> element that you generated. By default, the Report Manager
Web.config file is located in \Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\Web.config.
Save the file.
Repeat the previous step for each report server in the scale-out deployment.
(Do I need to repeat all 3 previous steps?)
Verify that all Web.Config files in the \Reporting Services\Report Manager folders contain identical <machineKey> elements in the <system.web> section.
Thanks

Jerry,
Thanks for the reply.
From the above View State Validation Steps,
For 1st step , how to generate validation key using .Net Framework?
for 4th step, Do I need to repeate all 3 previous steps?
Thanks

Change View State Based On Screen Orientation?

I'd like my app to change layouts based on the current screen orientation. I believe this is done through view states. I have three questions...
1) How do I check the current orientation?
2) Is there an event listener that will tell me when the orientation changes?
3) How do I toggle between view states?
Thank in advance!
UPDATE: I figured out the answer to question 3...
currentState = 'yourStateName';
UPDATE II: I figured out the answer to question 1 as well. I simply used the Capabilities object to determine the screens current width & height, then compare the two. All of this is in a function that gets called when the app launches:
public function checkOrientation():void
 var screenWidth:Number = Capabilities.screenResolutionX;
 var screenHeight:Number = Capabilities.screenResolutionY;
 if (screenWidth > screenHeight) {currentState='yourStateName1';}
 else if (screenWidth < screenHeight) {currentState='yourStateName2';}
Now all I have to do is figure out how to call this function when there is an orientation change. I tried the code below but get the included error:
stage.addEventListener(Event.RESIZE, checkOrientation); // ERROR: Access of undefined property stage
Why can't access the "stage" property???

Multiple view state best practice for IOS packaged app - Tabbed view or blank template?

TabbedViewNavigatorApplication or plain Application?
I have an iPad app that has a fairly complex main view. Has lots of view state changes. Before a user can get to that main view, however, they have to go through two other screens:
1. Authentication
2. Fill out and submit a small form (maybe 6 fields)
If they do those two things right, they can move on to the main view. If they don't, they can't move on and the main view shouldn't load.
Don't want a tab bar showing in the main view. Has to be full screen.
My thoughts were:
1. Start with the tabbed view template because it's built for this. Just figure out a way to hide bars top and bottom for main view.
2. Use a blank template and do everything with standarf Flex view states
Not sure...

Or you can go with door #3, a blank template with a ViewNavigator you use to push and pop your views from the Main.
View states are heavy. Avoid them like the plague in mobile apps. They are ok for small things like buttons and such, but that's about it.
