Highlight row in a multi-row block; disable cursor to go to individual item

We need to highlight the entire row in the multi-row screen for record selection by the user. But, in Oracle Forms, it keeps blinking in one of the items.
Pl. suggest some solution.

in the wehn-item_new-instance trigger,
if :poplist = 'specificvalue' then
Set_Item_Instance_Property('textitem', CURRENT_RECORD,
updateable,property_false);
else
Set_Item_Instance_Property('textitem', CURRENT_RECORD,
updateable,property_true);
end if;

Updating a value of a text item in a multi record block based on a change

Hi,
I need to change the value of a text item in a multi record block based on a change to another item's value in the same block.
Suppose there's a text item in a multi record block called dt1 which is of type date, which is changed in a particular record. I want to change the values of the another item in the same multi record block, for all other records by running a loop through all the records in multi record block. I dont want to do it on the press of a button, it should do automatically on change. Help me resolve this issue.

Dynamic visual attributes/multi-row blocks

We're using Headstart, Des2k V6.0.3.8. If you set preference CURREC = multi record block, you get the current record visual attribute (cg$current_record) attached to all displayed items in multi-row blocks. From the Headstart object library, these items also inherit a visual attribute of qms$item_font.
At runtime, Headstart code is invoked from the block's post-query trigger - this code dynamically assigns a readonly visual attribute to all items that are insert only, or the qms$item_font va to items that are update only. (Incidentally, it seems a bit strange that no va is assigned to items that are neither insertable nor updateable).
Assigning the va in this way seems to override the current record va for these items, which looks a little strange at runtime. I would prefer to see the current record va overriding the readonly/item_font va. In a future Headstart release, it would be nice if this functionality was configurable, but in the meantime can you suggest the easiest way of making this change to the Headstart code? I think it will be necessary to specifically set the va to stnd/readonly/current record in the when-new-record-instance trigger, & reset it on the post-record trigger. Once va's are being set dynamically, the current record attribute is pretty useless in multi-row blocks.
Incidentally - we've also changed the behaviour of va's in query mode processing. We wanted the query mode va to override the current record va; qms$record.highlight_items wasn't setting the selected va unless items have a current record attribute of DEFAULT. We wanted query mode to look the same regardless how many rows are in the block; it also looked a little odd in a multi-row block with overflow items, where the overflow items were being highlighted but the rest of the block wasn't. It would be nice if this was also a configurable option.

Cheryl,
Good point! It does look a bit odd. I'll take this into consideration for HSD6i.
To customize your app, try the following.
Copy qms$event_data_block from qmsevh50.pll to your application library.
Copy procedure set_nav_items_exg_record from the qms$record package in qmslib50.pll to your application library -AND GIVE IT A NEW NAME- like set_nav_items_custom.
Change your copy of qms$event_data_block to call this new procedure in the post-query event.

How can I handle data in a multi row block?

Hi all,
I have a form which contain a multi row block.
I put data in that block. Suppose that in the second column of
that block data no changes.I want to fill only the first cell of
the column and all the cells below first cell ( header) inherits
that value.
Example :
Block1
ITEM1 ITEM2
rec1 1 1999
rec2 2
rec3 3
When I insert in the table rec2 I want :
INSERT INTO(col1,col2) VALUES)(2,1999)!!!.
Best Regards !

Mr. Vali,
I suppose you want to enter ITEM2 value only in first record and
duplicate that value in subsequent records automatically. There
are couple of methods to accomplish this and the following is one
of them:
Add this code in WHEN-NEW-RECORD-INSTANCE trigger for block1.
IF :SYSTEM.RECORD_STATUS ='NEW' AND :SYSTEM.CURSOR_RECORD > 1
THEN
IF :ITEM2 IS NULL THEN
GO_ITEM('ITEM2');
DUPLICATE_ITEM;
GO_ITEM('ITEM1');
END IF;
END IF;
good luck

Dynamically Changing Labels for Multi Row Block Buttons

Forms [32 Bit] Version 9.0.4.1.0 (Production)
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production
On my local: Windows 7 OS
I am having a difficult time in doing the following in forms, and not sure if it can be done?
I have a multi row block,based on DB table, which displays filename and another column from the table.
It also has a push button on each row, which opens and displays the physical file from its source, when clicked. The filename thus can have 3 diff statuses depending on its sources and accordingly corresponding button should display appropriate label:
a) View Image (its is in content server and successfully imaged. In this case I display the file in the browser, from the content server, when the button is clicked)
b) View File (Display the file from file system)
c) View Error (Display imaging error message from the table, as file failed to make it to the imaging server)
I have this logic currently coded in the post query trigger, at the block level, and tried using set_item_property(button_id, label, <button_lable>), where I programmatically set the button lable, based on the file status (imaged, not imaged or has error) in that row. This wroks well, only if all the files in the multi row block have the same status. If each of them have diff statuses, then only last processed files's status gets reflected into the button label. For eg: The file in the first row of the block is imaged, and one in the second row has an imaging error. The button label for the first row should say 'View Image' and button for the second row should say 'View Error'. But now buttons for both the rows display 'View Error', as thats what got processed last!
I __can not use set_item_instance property for 'label'__ (which lets us dynamically change the label on the push buttons).
Is there any way to do this for ORacle forms? I am now playing with having 3 diff button items in that block, laying them on top of each other and showing only those that are appropriate and hiding the others... But I am not sure it is going to give me what I need? I think I am going to end up facing the same issues as in above case!!
Any expert advice is highly appreciated.
Thanks in advance for your time:

How to calculate total in multi-row block

How can I calculate and display the total amount in a multi-row

Hi,
I worked with similar type of requirement. If you are
working with Forms5.0 there is a new property of formula/summary
in property palette of text item. In the same block or in
control block create non database item( It's non base table item
in forms4.5). In it's property palette give the data type as
number and set the source item name and set summary property.(
opetions are max,min,sum etc available). This value will change
when you navigate from the source item( I mean after validation).
I think this is informative.

I have a multi row block with one item as check box.It is

the previous selected record should be marked as deselected.
How i can make these check boxes mutually exclusive ?

Hi
The check box can not be mutually exclusive.
This is a basic functionality.
You convert this item type into radio button.
It will satisfy your requirements.

Multi row block button

Guys, was wondering if anyone could help me out. I have a multi record block which displays about 10 rows on the screen to user, I have also added a button to this multi record block so there is 10 buttons, each button beside the corresponding row. When I click the button it processes the data in the current row and gives out a result, however it doesnt seem to work like that. If I query back and have 10 records displayed on the screen and then click the 5th button down which should process the data for the 5th record down it actually processes the data for the first record where the cursor currently is after the first query. Is there anyway I can get the cursor to go down to the record which corresponds to the button pressed? IE if i manually click on a record and then any of the buttons it processes whatever record the cursor is on, but I want it to automatically go to the record corresponding to the button when the button is pressed?
Thanks for any help I may receive.

Do you have your button in the same block as the items? It sounds like the button might be in its own database block which is why the rows don't match up. If that is the case then either move the button into the same block as the items, then row 5 for the button is the same row for that record, or you could add logic to your WHEN-BUTTON-PRESSED trigger that would navigate to the block that the items are in and move to the same record, but that would be a little whacky.

Multi row block record_group or cursor?

I've done a lot of research on the Forms OTN forum and can't find a solution to this problem. I'll continue to research until an answer is posted to this thread. I've used the forms forums and Metalink for years and they've been a great help.
My problem -
I have a multi-row block built off a view. Each row has a check box. The canvas also has a button. When the button is pressed, each record checked will be processed. The problem is, I need to sort the data selected (checked) before it's processed. To complicate matters, the sort criteria is not in the view. My plan was to build a cursor off the block, but I'm having problems populating due to the multi-row aspect.. I also tried building a record_group but again ran into complications with it being multi-row. I'm not sure which method to use since I haven't found a clear-cut solution.
btw - using 10gR2.
TIA,
abc

AB, you're sure not very clear on this.
Aweiden has the correct suggestion: Create a PL/SQL table in the form, rather than a record group.
Here are the steps I would follow:
1. User queries and displays the data, and then checks some checkboxes. Do not use a when-checkbox-changed trigger, since they can check, then un-check boxes.
2. When user presses the process button, loop through the block as Aweiden has done above. However, I would call a procedure from within the loop to look up the values from the Mel_Item table. Store the values returned from the procedure within your pl/sql table, adding one row to the table for each row in your block that was checked.
As a side note, how difficult is it to join the Mel_Item table with your view when you query the block? You could store those sort values from Mel_Item along with the data from the view.
3. Once you are done processing the data block loop, sort the pl/sql table. (Maybe I can find the code lying around here somewhere, but a table sort like that can be coded in maybe 20 lines).
I am not sure, but are you saying above ("...insert each row into another table (other information is different so its not duplicate rows entirely)...") that you are inserting the data from the user-checked rows into a database table? That is certainly easier to do than writing your own sort, I guess.
4. After the pl/sql table is sorted, loop through it one more time, processing the data in the required sequence.
Actually, pl/sql table processing is quite fast. You don't really need to sort the rows. All you need do is to step through the table checking for the first row to process (by finding the lowest value of the sort items). Process that row's data, then remove (delete) it from the table, then repeat the process until you have processed and removed every row from the array. I believe I would use this method rather than trying to sort the pl/sql table, OR inserting into a database table.

Overflow-field in multi-rows block

Hi!
How can i realize overflow-field in multi-rows block.
I place overflow fields in the footer area of block
and get value use ${uix.current['Description']} - but no have results.
Use javascript to set value of overflow-field?
thanks

Andreas,
I was most intrigued by your offered solution, so I created a test case. Unfortunately, this solution gives inconsistent results. Here was my test case:
1. Table: Planets
Columns: 3 (PL_ID, Name, Description
2. Added nine entries for all 8 planets and one record for Pluto (sorry, grew up with this being classified as a planet! :) )
3. Created very basic form to display all 3 columns in Tabular (Multi-Record) format and displayed 5 rows.
4. Created button in a Control Block to display Cursor_Record, Trigger_Record and Top_Record
- Set Mouse & Keyboard navigate to NO
Ran Form and navigated to each row and clicked on button. The following was my results:
>
Row 1: Cursor Rec: 1, Trig Rec: 1, Top Rec: 1
Row 2: Cursor Rec: 2, Trig Rec: 2, Top Rec: 1

Based on these results, the option to use the GET_BLOCK_PROPERT('BLOCK_NAME',TOP_RECORD) won't work either. :-( Unforntunately, displaying the MCHAR field in a static location or using Java (though hardest) are still the best solutions.

Microsoft optical mice and wheel scrolling in multi-row block

Hi.
One part of our form is a multi-row block. It has a scroll bar and upto this point you can scroll using the wheel when your mouse is on the scroll bar or if the pointer is anywhere within the multi-row block, you can use the wheel to scroll. This works for logitech ball and optical mice, ibm ball mice and even microsoft ball mice. All of them have the wheel. We do find a problem with microsoft optical mice whether its the explorer or optical brand. The wheel mouse works when the pointer is on the scroll bar but it does not scroll if the pointer is within the multi-row block. I have spoken with Oracle and of course they say its microsofts problem. Has anyone come across this? I have contacted microsoft but no word as yet.
Thank you,
Jayme

Forms has no support for the Wheel Scrolling action - if it works at all it's because the Mouse driver is clever enough to work out when it is on a ScrollBar and send the relevant Windows Events. You may find it also works in Multi-line text items.

How to re-query changed record in multi-row block after update in a called form

Hi,
I have a form that I use to perform searches, which is a multi-record block.
The user can navigate to a record, press a button on call another form which provides
more detail, and allows update of the record.
If the user changes it, and returns to the original search form, how can I re-query the
changed record to update the fields on the search form.
Is there a way other than to re-query the
whole block - a built-in to just update on record if it's changed on the database.
If not, can I use globals to pass back the data (since only a few fields are updatable),
and change the record without effecting its forms status.
Many thanks
Bernie

BD,
I haven't managed to look at a solution yet, but the block is a large multi-row block,
with an ORDER BY, and since it can return a large number of records, there is a short
delay. I was hoping there was a way of just
re-querying the one record, which was displayed
in the second form for update.
I'll give the query a go, or might try and pass back some globals with the update values.
By the way, DML Return Value is an excellent feature, but only works against Oracle 8.
It basiclly adds the RETURNING clause to any DML statement (see SQL manual), so that if
a trigger changes/adds values you didn't provide, it will return them back to you
so the values in your form are correct.
I use a trigger on the DB to populate history fields (create/update,who/when) and
the PK sequence. Using this feature, those values are returned to the block and displayed.
Regards
Bernie

Multi-row block with many image-java-beans

Hi, I want to create a multi-row block based on a table, e.g. emp with 5 records.
Then I want to add 5 java-bean images in the same block. Now I want to read from the db-table emp the blob-column with the image of the corresponding empno. Is this possible? How can I do this? Can someone give me a sample for this?
Thanx Bea

Multi-row blocks overlap on same canvas

Hi,
I have a problem designing a Form. We use Designer 6i and we generate with the Headstart 6.5 (first version) scripts.
I want to make a master-detail form and both of those blocks have to be on 1 tabpage. Both blocks also are multi-row block. Every time i generate it the two blocks overlap eachother in the canvas. I tried it with item groups for both blocks. I used the X and Y position in the properties of the block (module components) but they keep on overlapsing (Because it looks like both blocks start from the same starting point, so that makes them overlap). Is this a know bug or did anyone ever had the same problem?
Oh yeah, and on both blocks i did put the preference set from Headstart (QMS65_MULTI_RECORD_BLOCK).
Please help.
Kind regards,
Dave

Hi,
Set the "placement property" of the master block component to "new tab canvas page" and the detail component to "Same tab canvas page". You can set the size of the first master block for example: X = 102 and Y = 61
You dont need to set the size of the detail block.
Hope this helps you,
CB

Is it possible to requery only a single row of a multi record block?

Hi,
I have a data block say "Employees". This is a multi record block.
Requirement: Two users are working on the same form (front end). Now the user1 has made change for EMP1 The same is not reflected in the User2 Session. Hence i need to requery the values updated for EMP1
Issue: Since there lots of employees listed in this block. i do not want all the employees details to be required (Block requery). Instead is it possible to requery only a perticular record to be required?
Thanks,
Vidya

I think not possible........
Usually Approach is the data in grid table displays as read only and when user press EDIT button then they can edit one single record in a separate window.
ooh got one idea.......
may be create a save point and rollback to that particular save point ....... i hv never tried it but try it might solves your problem
there is a feature of Clear_form rollback to save point
PROCEDURE CLEAR_FORM
(commit_mode    NUMBER,
   rollback_mode NUMBER);
Parameters
If the end user has made changes to records in the current form or any called form, and those records have not been posted or committed, Form Builder processes the records, following the directions indicated by the argument supplied for the following parameter:
commit_mode     ASK_COMMIT Form Builder prompts the end user to commit the changes during CLEAR_FORM processing.
DO_COMMIT Form Builder validates the changes, performs a commit, and flushes the current form without prompting the end user.
NO_COMMIT Form Builder validates the changes and flushes the current form without performing a commit or prompting the end user.
NO_VALIDATE Form Builder flushes the current form without validating the changes, committing the changes, or prompting the end user.
rollback_mode     TO_SAVEPOINT Form Builder rolls back all uncommitted changes (including posted changes) to the current form's savepoint.
FULL_ROLLBACK Form Builder rolls back all uncommitted changes (including posted changes) which were made during the current Runform session. You cannot specify a FULL_ROLLBACK from a form that is running in post-only mode. (Post-only mode can occur when your form issues a call to another form while unposted records exist in the calling form. To prevent losing the locks issued by the calling form, Form Builder prevents any commit processing in the called form.) Edited by: BaiG on Apr 12, 2010 3:49 PM
