How do you get the value of a selected list item?
I have a drop-down list that the user can choose from. How do I get the value of what they selected? I thought I could do this by using the NAME_IN function, but I'm getting FRM-40105 Unable to resolve reference to item X. I don't know what I'm doing wrong.
Thanks!
Hi,
You can use an WHEN-LIST-CHANGED trigger, attached to the list-item itself. And, in this trigger, you can use the name of the item to refer its value.
For example:
:block_name.list_item_name

How do you get the value of an ELEMENT node?
Which API call do you use to get the value of a simple element node, e.g. <element>value</element>
The comments for getNodeValue in the header file oraxml.h says
This function returns the "value" (e.g. associated data) for the given node. Only COMMENT, CDATA and TEXT nodes have data, all others return NULL.
I've used an xpath expression to select the node that I want but now I can't get the value of the node because it is of type ELEMENT.
When use getNodeValue I get NULL just like the comment says. Not sure what to try next.For parsing with XPath

How do I get the values from a selected row.
I am using JDeveloper 9.0.5. On my page, I have placed a button within a table. The button has been assigned an event. The event is within my Action class. This class implements DataAction and has overriden the
processComponentEvents(DataActionContext actionContext);
method.
Question: While I am within the processComponentEvents method, is it possible to obtain the values of selected row?Good Morning Jeffery,
First off thanks for your clear explanation. I have a few related questions as noted from your response:
There are two ways to communicate the desired model row between the UIX view and the struts controller. One way is to use the singleSelection component in your table and put your buttons in the singleSelection's contents.
When the user selects the radio button for a particular row and then clicks on one the buttons, a built in event handler in UIX will set the current row in the model to be the user selected row. Therefore, your Struts action can operate on the currently selected model row.
When you drop a UIX table from the data control palette it is automatically set up in this way (with a single selection).
Ok, Lets say that i've set everything up as you described. Not lets say that the button was pressed and I hit the overriddenprotected void processComponentEvents(DataActionContext actionContext) throws IOException, ServletException ;
When I look at the request object, I do not see the values. How do I get access to the rowkey at this point?
Some people, however, want to actually render buttons in their table rows, and have those buttons initiate an action on their row. If you are doing this, then you need to pass the row id to your struts action as a parameter, which means that you need to know the row id when you are rendering a button for a given row. There is an EL expression that will return the row-id for the current row, it is:
${uix.current.rowKeyStr}
which is not so obvious or well documented in the preview release (sorry) but should be for the production release.
A generic code snippet would go a long way to shedding some light on that. I guess I am use to using JDeveloper 9.0.3. It seems,"to me", that JDev 9.0.5 has put a completely new twist on things. I find myself wondering when I can use the 9.0.3 syntax and when
should not. If your team has any short source toys around which demonstrated using rowkeys, or accessing the internal parts of the
struts controller, I would find that invaluable. It dose not matter if this information is documented.
Thank you -
ListView + MVVM: How do I get the value of a selected cell?
Hi,
I love programming WPF using MVVM, but sometimes easy looking problems lead to unbearable suffering.
Here is my problem: I have a simple list view with about a couple of columns. All I want to do is to copy the cell content to clipboard, when the user right-clicks on a cell.
<ListView Grid.Row="0" ItemsSource="{Binding Articles}" SelectedItem="{Binding SelectedArticle}" SelectionMode="Single">
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn Header="ID" Width="70" DisplayMemberBinding="{Binding Path=ID, Mode=OneWay}" />
<GridViewColumn Header="Name" Width="150" DisplayMemberBinding="{Binding Path=Name, Mode=OneWay}"/>
<GridViewColumn Header="Price" Width="100" DisplayMemberBinding="{Binding Path=Price, Mode=OneWay}"/>
<GridViewColumn Header="Description" Width="70" DisplayMemberBinding="{Binding Path=Description, Mode=OneWay}"/>
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>
Without MVVM I probably would have used the some Click-Event and extract the info from the event args. But of course I don't want to break the MVVM pattern.
But if I use some kind of event binding I cannot find a way to retrieve event args or the sender object:
<i:EventTrigger EventName="PreviewMouseRightButtonDown">
<i:InvokeCommandAction Command="{Binding CopyCellValueToClipCommand}"/>
</i:EventTrigger>
Using this trigger I can react to the desired event, but how can I retrieve the cell value?
I really hope you guys have a clue.
Thanks for your help,
MichaelI'm not so sure about listview, I rarely use them for more complicated requirements.
I would use a datagrid.
You can bind a cellinfo:
http://stackoverflow.com/questions/20080130/how-to-bind-currentcell-in-wpf-datagrid-using-mvvm-pattern
<DataGrid AutoGenerateColumns="True"
SelectionUnit="Cell"
SelectionMode="Single"
Height="250" Width="525"
ItemsSource="{Binding Results}"
CurrentCell="{Binding CellInfo, Mode=OneWayToSource}"/>
and
private DataGridCellInfo _cellInfo;
public DataGridCellInfo CellInfo
get { return _cellInfo; }
set
_cellInfo = value;
OnPropertyChanged("CellInfo");
MessageBox.Show(string.Format("Column: {0}",
_cellInfo.Column.DisplayIndex != null ? _cellInfo.Column.DisplayIndex.ToString() : "Index out of range!"));
You can use index and bind selecteditem or get contents of cell:
public DataGridCell GetDataGridCell(DataGridCellInfo cellInfo)
var cellContent = cellInfo.Column.GetCellContent(cellInfo.Item);
if (cellContent != null)
return (DataGridCell) cellContent.Parent;
return null;
Hope that helps.

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?
Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

In your backing bean you will need to add a new variable to bind your control to, I think this variable needs to be of teh "HtmlSelectManyCheckbox" type. The on your jsp page you can add binding="#{myBean.myVariable}".
When you want to get the values of the selectMany in your backing bean, you can call the getSelectedValues() function on your HtmlSelectManyCheckbox variable.
in backing bean:
private HtmlSelectManyCheckbox hsmc;
public HtmlSelectManyCheckbox getHsmc(){
return hsmc;
public void setHsmc(HtmlSelectManyCheckbox hsmc){
this.hsmc = hsmc;
public void someFunction(){
Object[] obs = hsmc.getSelectedValues();
}On jsp page:
<h:selectManyCheckbox
id="cartas"
layout="pageDirection"
value="#{store.cartas}"
binding="#(myBean.hsmc}">
<f:selectItems
value="#{cartas}"/>
</h:selectManyCheckbox> -
How we can get the values from one screen to another screen?
hi guru's.
how we can get the values from one screen to another screen?
we get values where cusor is placed but in my requirement i want to get to field values from one screen to another screen.
regards.
satheesh.Just think of dynpros as windows into the global memory of your program... so if you want the value of a field on dynpro 1234 to appear on dynpro 2345, then just pop the value into a global variable (i.e. one defined in your top include), and you will be able to see it in your second dynpro (assuming you make the field formats etc the same on both screens!).

How can we get the value of the key field in a custom data model using governance API?
Dear Team,
How can we get the value of the key field in a custom data model, to be used for manipulation of the change request fields using governance API?
Any kind of help would be sincerely appreciated.
Thanks & Regards,
Tushar.Hi Michael,
Thanks for direction. Let me give more context on this as I'm interested to get more details..One of the issue was to read cross entity field values on UI based on user action and set other entity field behaviour...It is similar to what is being posted here.
For ex: Reading MTART from Basic Data UIBB in MM MDG UI and set the field properties in some other custom entities say ZZETEST. This cannot be done using UI BADI as it only supports single entity at a time and not cross entity. So alternatively we found a solution where we can enhance existing PLMB feederclass cl_mdg_bs_mat_feeder_form by reading the model and the entity as needed as it it proved that it supports cross entity UI field behaviours and so business requirements.
This is a workaround for now.
So the question is How do we achive it using governance API for cross entity field behiaviours.?or what is the right way doing this.
Can we do that using governance API and its' methods?
In the Governance API doc you provided below has referring to below external model as part of gevernance API.
The active or inactive data (before or during the derivation or the check) can be read
with the external data model interface IF_USMD_MODEL_EXT with the method READ_CHAR_VALUE and
the corresponding READ_MODE parameter. To avoid unnecessary flushes (derivations), the NO_FLUSH
parameter should b
e set to ‘X’.
Thanks

How do you get the count of number of checkbox selected?
hi,
plz tell me how do you get the count of number of checkbox selected?Not sure what you are doing so I will attempt to answer your question. If have one question which can have multiple answers you have will recieve an array so you have to do getParameterValues("name") and move it into an array.
If you have multiple questions and only value will be selected do a getParameter("name") on each form element.
HTH, if not provide more detail.

Once pictures are moved from your camera to your iPad (using the camera connection kit), how do you get the photos off of the iPad? They do not show up in my photo stream or my iCloud. I am able to see any photo I took on the iPad using the iPad camera (in iTunes, photo stream, or when I open windows explorer and browse the iPad director), however I cannot see any photos transfered from my camera to the iPad. The camera connection kit must have put my photos in a directory I cannot get to and cannot sync.
