How to populate text fields with data present in a table

Hi,
The page i'm building has got a select list for the primary key column and text fields corresponding to rest of the columns in the table.
upon selecting some value from the list, the data corresponding to that row should get populated in the respective items. I don't want to add source in each item. can't i create a process or something else where this is done for each item.
for eg there's a table with columns A(primary key) and B.
there is a text fields on this page.
this textfield should populate the data from the table whenever i submit the page such that teh value in B is select B from tablename where A = the selected value.
Thanks

So I assume page was not built using a wizard. Why on earth you would want to I dont know, but you could create an "After Header" pl/sql process to populate the relevant fields, assuming the id was know on entry to the page. If you want to select the id on the page and then populate the fields, guess you will need to use a "Text Field (always submits page when Enter pressed)" and then use an "On Submit" process to populate the items.
If you are using an Automated Row Fetch, remember to select "Set memory Cache on Fetch" in that process.
Hope this helps.

Auto populate text fields with a trigger such as entering text into input fields in ADF

Hello all,
I am not able to auto populate text fields with a trigger such as entering text into input fields in ADF.
I tried AdfFacesContext.getCurrentInstance().addPartialTarget(val); in the back end using setter method of input text field.
its not working ..
is there any way to achieve it
Regards,
Shakir

Hi,
Always mention your JDev version.
The valueChangeListener would fire only when you set the autoSubmit property of the field to true. Can you elaborate your requirement? What do you mean by related data? Are you performing some sort of search?
If you want to get the value you entered on the field, just set autoSubmit to true and get the new value from the valueChangeListener. If your requirement is something like as and when you type, do something, you need to check out this approach :https://blogs.oracle.com/groundside/entry/auto_reduce_search_sample

Having issues with populating a Text Field with data from 2 other fields

I have 3 fields Tools_1a_pri, Tools_1a_pri_other, Tools_1a_pri_txt.
Tools_1a_pri is a drop down combo with a predefined list. One of the options is "Other". When "Other" is selected, the text field Tools_1a_pri_other becomes visible for users to enter the name of the other tool.
The Tools_1a_pri_txt is a text field with a calculation that shows either text stating that no tool has been selected or the Tools_1a_pri & or Tools_1a_pri_other.
When I select one of the predefined tools, everything works. When I select other, it appears that nothing has changed. It requires that I click on another field before it populates. This is confusing to the user.
Tools_1a_pri Validate code
this.getField("Tools_1a_pri_Other").display = event.value=="Other" ? display.visible : display.hidden;
Tools_1a_pri_txt Calculation code
//if nothing is selected, do the following
if (getField("Tools_1a_pri").value.length < 2) {
event.target.textColor = color.red
event.value = "No primary tool identified";
}else if (getField("Tools_1a_pri").value != "Other") {
//otherwise do this if other is selected
event.target.textColor = color.black
event.value = getField("Tools_1a_pri").value;
}else if (getField("Tools_1a_pri").value = "Other") {
//otherwise do this if other is not selected
event.target.textColor = color.black
event.value = getField("Tools_1a_pri").value + " - " + getField("Tools_1a_pri_Other").value;

You made the classic mistake of using the assignment operator in an if-statement instead of the comparison operator. Change this line:
} else if (getField("Tools_1a_pri").value = "Other") {
To this:
} else if (getField("Tools_1a_pri").value == "Other") {

Livecycle populate text field with multiple records from list box

Can someone tell me how can I populate a text field from list box when I have multiple select.
Here is example:
List box consist: Hello
                         World.
I want to see this in text field: Hello,World.
Thanks!

Hi Legro
I don't know if I understand you correctly, but you can do something like this:
----------------- java script begin ---------------------------------
//Reset text field
TextField.rawValue = "";
//loop through items in listbox
for(i = 0; i < ListBox.length; i++)
          //if item selected
          if(ListBox.getItemState(i))
                    //check if Text field value if null
                    if (TextField.isNull)
                              TextField.rawValue = ListBox.getDisplayItem(i);
                    else
                              TextField.rawValue = TextField.rawValue + " " + ListBox.getDisplayItem(i);
----------------- java script end ---------------------------------
I have attached an sample PDF so that you can see how it works!!

How to populate a ComboBox with data from a WebService

I have a simple application that has a DataGrid that gets its
data from a web service. I would prefer to put that data into a
ComboBox instead of a DataGrid. My web service returns objects.
Anyone have any idea how to do that?
<mx:DataGrid id="dgProjects"
dataProvider="{ws.getProjects.lastResult}" >
.....<mx:columns>
..........<mx:DataGridColumn dataField="projectID"
headerText="Project ID" width="100"/>
..........<mx:DataGridColumn headerText="Project Name"
dataField="projectName"/>
..........<mx:DataGridColumn headerText="Doc UNID"
dataField="docUNID" visible="false"/>
.....</mx:columns>
</mx:DataGrid>

I tried that but it doesn't work. However, I just found part
of the solution and that was to add labelField="projectName".
That worked. Now, I want to glue together projectID with
projectName and a dash between them. So I changed it to labelField
= "projectID - ProjectName" and that causes the combo box to
display [Object] [object].
Any ideas how to glue those items together?

How to create a field with 1200 chars length

Hi,
Will anybody let me know how to create a field with length 1200 in a table.
Regards,
Madhavi

Hi Madhvi,
Other thing what you can do is
1. First create a Table type.
Goto SE11-> Dataelements ->Table type
There on the next screen select Predefine radio button & there provide data type & size.
2. Create a structure having a field typa of Table type created before. say that field is quant.
Now in your program refer that structure to create an internal table & work area.
Now if u append ur text to the field quant.
try creating line type of size more that 255 if it works then fine other wise reduce it.
Note:: This will be a deep structure.
so first append value to the field quant, the at the end of first record append valu to ur internal table.
thanks

How to make a list item field with DATE data type?

I have a column with DATE data type. Using forms 6i I want to generate a poplist list item field with this column while the value of the elements in the list to will be day names like SATURDAY,SUNDAY,MONDAY. if we change the data type from date to char, it will work properly but now with DATE data type behind it, it gives the following error message
"FRM-32082: Invalid value for given item type.
List WEEKREST
Item: WEEKREST
Block: EMPRESTS
Form: MODULE3
FRM-30085: Unable to adjust form for output."
Using forms 6i how to make a list item field with DATE data type which can hold day names?

Set your date column as a hidden (non-displayed) field. Create your list item with the varchar2 day names. Create the list item as a non-base-table field that accepts the text values of day names. On that field, create a when-validate-item trigger that translates the text into a real date, which it then uses to set the value of the actual base-table item.

How do I add and remove text in a text field with a checkbox?

How do I add and/or remove text in a text field with a checkbox?
this is my script in the text box......
event.value="Hello, this is my narrative. \r\n\nFamily: \r\n\n" + this get.Field("FirstName").value + " " + this.getField("LastName").value + was born on"=this.getField("DOB.value + "\r\n\n + this.getField("drpField").value + "\r\n\n" + this getField("Father").value
The text box looks like this...
Hello, this is my narrative.
FAMILY:
John Smith was born on 08/02/2000
Boby Lou
Jack Smith
I need to add/or remove the father field (Jack Smith) & r/n/n with a check box.
Does anyone know how to do this?

There are multiple errors in your code...
Use this code instead (adjust the name of the check-box):
var msg = "Hello, this is my narrative. \r\n\nFamily: \r\n\n" + this get.Field("FirstName").value + " " + this.getField("LastName").value + was born on" + this.getField("DOB.value) + "\r\n\n" + this.getField("drpField").value;
if (this.getField("FatherCheckBox").value!="Off")
msg += "\r\n\n" + this getField("Father").value;
event.value = msg;

if :p3_note_id is null
then
insert into notes (project_id, note, notes_month, notes_year) So, p3_note_id is NULL.
Another option is that you have a trigger on table NOTES that generates a new note_id even for an update.

How to populate an array with random text files.

I am making a Jeopardy program. I have my program set up so that it retrieves 5 random text files. I just want to know how I populate one array with all the lines from the text files my program is retrieving.

You can read a textfile line by line and add each line to an ArrayList. An ArrayList is very much like an array only that it's "open ended". You can start adding lines without first knowing how many you're going to get. If you still want an ordinary "static" array when you're finished reading lines you can easily get one from the ArrayList and then drop the ArrayList.

Auto populate blank text fields with n.a from a button or on print out.

This seems straight forward but I cannot find an existing questions on this topic.
I would like to add a form function that will fill any blank text fields with n.a. I do not want to use the default field value as I think it will cause confusion and cannot be applied for text fields formatted for dates. Is it possible to run a script that can do this? It would be OK if the action was triggered from a button or print activity after the rest of the form has been completed.
Any thoughts would be appreciated.
Thanks

The question is whether your form is used only for filling out on screen (and not as a level 0 form, being printed out and filled out manually).
If so, why not make the default value of the concerned fields to be "n/a" (or whatever you want to name them). That would relieve you from any validating before printing.
Otherwise, you could maintain a list of field names which should get the n/a value if empty. This list would be an array.
Your code in the willPrint event (if you want to have it reliably) would then look like this:
for (var i = 0 ; i < nafieldarray.length ; i++) {
if (this.getField(nafieldarray[i]).value == this.getField(nafieldarray[i]).defaultValue) {
this.getField(nafieldarray[i].value = "n/a") ;
HTH.

How to add an animation to a text field with two lines?

I have a text field with two or more lines. Why isn't it possible now to apply a text animation?

For certain tasks, Titler and its Presets can be very good, and can simplify things greatly.
However, when one gets beyond the limitations of the Titler, I really like to create my Titles in Photoshop, and Import those as Still Images into my Project. I then use the power of Keyframing various Effects over time. This allows me much more control, BUT does require more hand-work. Still, that added control is too important to me, and I sort of like doing the handwork.
For the "alignment" of multiple Titles, to get multiple lines of Text, you can create the first Title, and then chose Duplicate Title. Initially, that will be identical, but you just change it, as is necessary. After you have changed that "second line of Text," place that Duplicate on the next Video Track, above the first Title, and use the Fixed Effect>Motion>Position, to move it down, to where it would be (by the height of the font, plus any desired Leading), if one had created a second line of Text on one Title.
I also like to use Alignment Grids, when things get critical, and create those in Photoshop, with a trasparent background, and just place them, on say Video Track 2, with all of my Titles above that. Just do not forget to remove any Alignment Grids, before you Export/Share the Timeline, or they will be part of the output video.
For more background on Keyframing (so very useful with more than just Titles), Steve Grisetti has done a multi-part tutorial, available as Basic Keyframing on Muvipix.com. I highly recommend it. Keyframing is simple to do, but can be a bit of a tough concept to grasp initially, and it's a subject that is tough to write about - takes longer to type instructions, than to do the work.
Good luck,
Hunt
PS - Do not know if you saw them, but Titler has two Alignment Tools - Align Horizontally, and Align Vertically, that can be helpful to center Text.

Populate Text fields from Select List

I have a select list when selected should populate two text fields with values based on SQL Query
Eg. The select list is for empno and populates ename and sal in two different text fields.
I have looked at Denes' example http://htmldb.oracle.com/pls/otn/f?p=31517:42 It is very good but the only problem I am facing is how to populate more than one fields.
Any help will be appreciated.
ZRH

Hi
That would depend on where the SAL data is. If it's on your page, then you could probably do something with javascript. If not, you would have to do some Ajax to retrieve the value from the database. Have a look at: http://htmldb.oracle.com/pls/otn/f?p=31517:80
Your select list could include both the ENAME and SAL values and your existing javascript would then just split the data into two parts and insert them into the appropriate fields.
