How to get the value a user just enter into a table???

hi
i have a table that adds a new row when a user clicks ADD button. i was able to implement this part, now the user needs to enter some data into this row, i need this data to save into file. how can i get this data from the row?????? thank you.

is there some kind of even that is fired when user enters data into a cell? you are saying that the data is already in the table model after user enters data. then i need to get a tableModel by calling
TableModel tm = JTable.getModel();
and then use this tm to get value? using what? getValueAt?

How to get the value of an input text in a table

all,
i have an adf table component on my jsf page and i added an input text component to one of the table columns. how do i access the value of that input text in my backing bean? normally, i would just do a getValue(), but because the input text is in the table i'm assuming it has to be treated as an array somehow.
any help would be appreciated,
paul
btw. jdev 10.1.3

Frank,
I found a solution to fetching the column values. I created a transient attribute on my view object and bound my column to the transient attribute. Then I used this post from Duncan Mills
http://groundside.com/blog/DuncanMills.php?title=adf_validation_context_in_a_jsf_table&more=1&c=1&tb=1&pb=1
to get to the data by looping through the table rows.
However, I'd still like to use the value from this transient attribute in logic to populate some other columns in the table. I
for example, here's the content of what's submitted:
name phone transient
==== ===== =======
paul null 555
mary null 444
In my backing bean I'd like to get the rows from the table and read the value of the transient attribute, pass it through a function, and set the value of the column phone to some value for each row. Then have that processed to update the db. Is this possible?
Thanks,
Paul

How to get the dates a user has logged into the portal??

I need to know all the times and the dates a user has loggin to the portal? Do you know any way to do this? I was trying to use "successfullogoncount" from UME_STRING of the PCD database but it doesn't say anything about the dates. I also try to use "lastsuccessfulllogon" from the sama table but, as the name says, it just give me the last date of logon... Please help!!!

Hi Pablo,
probably you could work with Portal activity reports.
This can generate reports on activity in the portal, either reports on how many users were logged on to the portal or reports on the most popular pages and iViews.
look out on this weblog at
https://www.sdn.sap.com/sdn/weblogs.sdn?blog=/pub/wlg/1242. [original link is broken] [original link is broken] [original link is broken]
From this you can know which user has logged on at which date and time.
If you are not looking for Portal activity reports try this:
You can get this information in the Visual Administrator of the J2EE Engine.
Goto Security Provider Service -> Runtime -> Login (Sessions).
This would return a table showing the users along with the logging in start date&time, (if logged out) log out date&time, user-Ids, etc.
Hope this helps,
Regards,
Uma.

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

Uday

How to get the value from databank

Hi,
How to get the value from databank? and how to set the same value to visual script object?
thanks,
ra

Hi,
You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
Thanks

How to get the value from textInput Component to perform calculation?

I need some help here...I'm trying to get the value of user input from the TextInput Component which is the age, height and weight to calculate the bmr and display the result in member("result").text.
How am i suppose to let the integer pass through in order for me to perform calculation? Would appreciate if anyone can help me out with this, thanks!
Below are the formula :
The Harris Benedict equation estimates BMR:
For women: (9.56 x w) + (1.85 x h) – (4.68 x a) + 655
For men: (13.75 x w) + (5 x h) – (6.76 x a) + 66

Assumed that this section is only for male ...it still show error saying script error : String expected for
on mouseDown
member("result").text = (13.75 * value(member("weightText").text)) + (5 * value(member("heightText").text)) - (6.76 * value(member("ageText").text)) + 66
end
Do i have to add in "put sprite(x).text -- where x is the number of the sprite that is the text input." ?

How to get the value assigned in dropdowmlistbox as well as radio button

Hi Everybody,
   Please help me to find the solution for the following:
   1. How to get the value assigned in dropdowmlistbox?
   2. How to get the value assigned in radio button?
I am waiting for the answer and reply...
Thanks & Regards,
ShanthaKumar.KA.

The radio button has a name attribute. That name attribute should be the same as the bean property. Then you just need a
<jsp:setProperty name="mybean" property="*"/>
and the bean's set method will be called for the value of that radio button.
so...
<input type="radio" name="doit"/>
class MyBean
public void setDoit( boolean yes )
//do whatever here
}

How to get the values from repeated frame?.

Hi
how to get the values from repeated frame?. i have to disply the first 3 digits in another place in my report.
i have field empno in repeated frame and i want to disply first 3 digits in another place in the same report.
thanks

How often do you need to display it? It sounds like you might want to base a summary on that formula with a function of first or last. If it's a per page basis, it can be a page level summary. If it's at a higher level repeating frame, then you can create the summary at that level. I'd suggest taking a look at the online help for summaries using the first/last functions.
Hope that helps,
Toby
