Custom HTML or JS in Column Headers in Answers
All,
I am primarily a web developer, but a co-worker asked me how a site was doing a particular effect (they had set the title parameter of a node, and it was showing up like a tooltip). He wanted to set it up on the column header of an Answer, so that when a user scrolled over it, it would display some metadata about the field. I said it should be really easy to do.....
So after a day of reading up on Seibel/Oracle Analytics, I'm about ready to strangle the developers.
I had assumed (apparently incorrectly), that I could set the column header text, and just include an html element with the title set. Simple enough, after that didn't work (it never parses the HTML, it just renders it as character entities). I thought, surely it would be an easy task to track down the actual html templates that were being used to generate those tables. No such luck there either.
Ideally, I'd like to edit the "advanced" tab report xml, and just say something like:
<saw:title>My Tooltip Title</saw:title>
but I can't find any documentation on that XML document format.
Surely though, the original developers did not embed HTML table info inside the magical mystical saw.dll....
Any help would be much appreciated.
Thanks in advance,
James
Update:
This is interesting. So when my coworker asked me how get the tooltip effect, I said it was super straight forward. All they had to do was something like:
<span title="My tooltip">My Column Header</span>
And it would work. After trying all kinds of HTML, I despaired of a simple fix.
Then we set the HardenXSS flag to false in the server instance config file, and I tried that exact code again. It still was not parsing the column header correctly. Then one of my other coworkers, tells me that he put a line break tag in, and it rendered the break.
o.O
So I tried the following:
<b title="My tooltip">My Column Header</b>
Which of course worked. Why is span being discriminated against? I have no idea.
So basically, for column header tooltips, disable XSS hardening, and use a bold tag. (why bold? it was the first thing that came to mind, and since the default font-weight of a table header is bold, it should be practically unnoticable).
The next question is, what exactly is the impact of disabling the HardenXSS. I'm not sure if it allows certain HTML elements only, or if it allows any HTML (or more to the point the script tags). I wonder if anyone has done a vulnerability assesment of having hardening turned off.

JTable column headers not displaying using custom table model
Hi,
I'm attempting to use a custom table model (by extending AbstractTableModel) to display the contents of a data set in a JTable. The table is displaying the data itself correctly but there are no column headers appearing. I have overridden getColumnName of the table model to return the correct header and have tried playing with the ColumnModel for the table but have not been able to get the headers to display (at all).
Any ideas?

public class PublicationTableModel extends AbstractTableModel
PublicationManager pubManager;

Multiple column headers in a single DataGrid?
Suppose i wanted to display information on, say, invoices.
So, i want to display one part of my DataGrid with only invoices from the last 30 days, the next section for 30-60 days old, and the third section is 90 days+ old.
I want it to look, basically, like this:
30 Days or less
Customer Days Old amount
Mr. X cleaning 15 20.76
7-11 3 7.11
30-60 days old
Customer Days Old amount
Barney's 75 12.34
Watto's part shop 80 1200.89
90 days or older
Customer Days Old amount
Sprint 144 30.63
Is it possible to do this in a single DataGrid? I want the mulitple column headers, but want to be able to get rid of them and combine all this data into a single DataGrid with all invoices, if needs be. In that case all but the top column header titles would disappear.
Any info on this is appreciated.
thanks!Hi,
You can do grouping with advance datagrid.

The above code executes well with no problem at all!
As you can see the file to which i create and save and open my pdf report is

The column headers of table in pdf report from c# windows forms using iTextSharp are
"Reprocessing Date","Patient Name","Dialyzer(Manufacturer,Size)","No.of Reuse","Verification" and
"DialyzerID".
However the problem i am facing is after execution and opening of document is my
column headers in table in pdf report from
c# and datas in it all appear in bold.
I have browsed through net regarding to solve this problem but with no success.
What i want is my pdf report from c# should be similar to following format which i was able to accomplish in vb6,adodb with MS access using iTextSharp.:
Given below is report which i have achieved from vb6,adodb with MS access using iTextSharp
I know that there has to be another way to solve my problem.I have browsed many articles in net regarding exporting sql datas to above format but with no success!
Is there is any another way to solve to my problem on exporting sql datas from c# windows forms using iTextSharp to above format given in the picture/image above?!
If so Then Can anyone tell me what modifications must i do in my c# code given above so that my pdf report from c# windows forms using iTextSharp will look similar to image/picture(pdf report) which i was able to accomplish from

I have approached Sound Forge.Net for help but with no success.
I hope anyone/someone truly understands what i am trying to ask!
I know i have to do lot of modifications in my c# code to achieve this level of perfection but i dont know how to do it.
Can anyone help me please! Any help/guidance in solving this problem would be greatly appreciated.
I hope i get a reply in terms of solving this problem.

Unable to turn column headers bold in Word table using VB Script
I have created a table in Microsoft Word 2010 using VB Script (this is via the script engine that forms part of HP Quality Centre functionality). The table itself is OK, 2 columns with centred headers. However, I am unable to make the column
headers bold. I have spent hours searching the net and trying various options to no avail can somebody please help me.
Set objWord = CreateObject("Word.Application")
Set objDocument = objword.Documents.Open(Src_Dir & template_file
Const wdAlignParagraphCenter = 1'var to control justification of the table columns
Const NUMBER_OF_ROWS = 1 'number of rows in intial table
Const NUMBER_OF_COLUMNS = 2 'number of colums in the intitial table
'search for the "TAA_TABLE" bookmark embedded in the document template, this is where the table will be created
Set objRange=objDocument.Bookmarks("TAA_TABLE").Range
'create the table
objDocument.Tables.Add objRange, NUMBER_OF_ROWS, NUMBER_OF_COLUMNS
Set objTable = objDocument.Tables(2)
'populate column headers
objTable.Cell(1, 1).Range.Font.Bold = True
objTable.Cell(1, 1).Range.Text = "Sub Contractor"
objTable.Cell(1, 2).Range.text = "TAA Number"
'centre the column headers
objDocument.Tables(2).Rows(1).Select
Set objSelection = objWord.Selection
objSelection.ParagraphFormat.Alignment = wdAlignParagraphCenter
'format the table with plain grid lines
objTable.AutoFormat(16)
'set the column widths
objTable.Columns(1).Setwidth 230,0
objTable.Columns(2).Setwidth 230,0
Any help is graetfully appreciated, as this is driving me wild.
Cheers,Hi Citronax,
I haved noticed that you used objTable.AutoFormat to format the table. Based on my understanding, this fuction will applie a predefined look to a table.
After I move the code which bolder the text behind this line of code, it works well for me.
'format the table with plain grid lines
objTable.AutoFormat (16)
objTable.Cell(1, 1).Range.Font.Bold = True

Interactive report Column headers
Hi ,
I am using apex 4.2,
My IR report contains more than 500 rows , so when I scroll down , I am unable to see the column headers.
How to make column headers to be visible even when I scroll down.
Please guide me to achieve that .
Thank you,
Nihar Narla.There is/was a plug-in (IR Plugin Package) that claims to support this.
See: http://apex-plugin.com/oracle-apex-plugins/dynamic-action-plugin/ir-plugin-package_108.html
I've never used it myself.

Hiding the column headers in boxed view
I've created a custom list that I'm displaying in boxed view. Here's a sample of the columns:
Business Systems Manager
Project lead
Project number
SFA?
Etc...
In boxed view, it displays like I have it here - vertical. The names of the people and info display next to each item.
However, the web part is still displaying the column headings across the page like in this example:
Business Systems Manager - Project Lead - Project Number - SFA? - etc...
Some of my custom lists carry on for 12 or 13 columns and the main page view has about 6 or 7 of them so needless to say, the extra real estate the column headers (which are completely redundant because the column heading info is IN the boxed view!!!) are taking up is killing the layout of the page.
Is there anyway to remove the column headers from the boxed view with out of the box Sharepoint? Or is Designer required?
Thanks!
LorraineThis worked well for me:
1) Add a Content Editor Web Part
2) Click Source Editor
3) Enter the following code:
[css] <style> .ms-viewheadertr { display: none;} </style> [/css]
4) Select Save
5) Go to Layout and Select 'Hidden' -
Custom html elements in the portal pages output rendering.
Hi,
This is regarding branding the site. Since we have to use common css for all web applications, the html output rendered by the AquaLogic doesn't give the required style.
AquaLogic generates html table elements for pages, columns, headers, footer etc. But we need <div> tags instead of 'table' & 'td' tags. If this is not possible 'table' EMBEDDED inside 'div' will also help us.
See for example DIV tag is placed (see 2nd line in given html) around the columns
<br><br>
(td class="columnOne") -<!--Begin Portlet Column 0-->
<br>
(DIV ID="columnNarrowWide") -
<br>
(table class="portletBase" id="pt-portlet-252")

Edited by rajesh_yg at 03/22/2007 12:06 PMSome of your post was garbled due to HTML-escaping issues, but I think what you're asking is for a DIV-based layout rather than that TABLE-based layout for MyPages and Communities.
One of our customers asked us for exactly the same thing and I'm working with an on-site designer to come up with something DIV-based. If it's possible, it's going to require extensive customizations to MyPortalContentView.java or MyPortalContentView.cs (if you're on .net). Using dynamic discovery (more specifically, View Replacement) is the way to go, but this task is a bit daunting, even for me (and I've been working with Plum/ALUI for almost ten years).
If I can get something working, I promise to post a solution on [url http://dev2dev.bea.com/blog/bucchere]my dev2dev blog.
In the meantime, if you want to attempt this yourself, edoc has a [url http://edocs.bea.com/alui/devdoc/docs60/Customizing_the_Portal_UI/Using_View_Replacement/PlumtreeDevDoc_Customizing_View_Intro.htm]guide to View Replacement that walks you through the process for both Java and .NET portals.

Column headers in forms are garbled
Hi,
I have one issue regarding folders in forms. User has set some custom folder on a form with following properties.
Autoquery = Never,
Check boxes checked : Open as Default, Public.
User has set this folder as default folder. When user goes to particular window, he sees some column headers are garbled and not shown correctly.
I checked user's .fmb file and compared with file on arcs log and did not find any differences between them.
Can anybody suggest what might be the cause for this? What kind of set up may cause this?
Thanks,
AkshayThanks much. I found the correct file, deleted it, and the column headers and data match up again.
I found the correct file by searching the directory for one of the column names that occurs in the view (though I had to find both instances of "COLUMN_NAME" and "COLUMN NAME" (without the underscore)). Not sure why there were files with both versions.
Do you know if there is any way to prevent those XXXXXXXXXTableSettings.xml files from writing all together (oracle.javatools.controls.nicetable.NiceTablePersistentSettings)? I looked through the SQL Developer preferences but nothing jumped out as being the setting to switch off.
Should I be doing anything in particular to bring more attention to this potential bug so it might get fixed in a future release?
Thanks again,

JTable column headers not showing up
I have a JTable inside a JScrollPane which, in turn, is inside a JTabbedPane.
I created a TableModel which extends AbstractTableModel as per the java Swing Tutorial examples.
In that model is an Object[][] object for the data called rowData, and all the data displays in the table perfectly.
I also have a String[] object called columnNames to define the column headers. ..the column names are coded directly into the object.
i.e.: String[] columnNames = {"John", "Janet", "Jamie", "Jennifer"};But the column names don't display at all.....all I get in the column headers is 'A', 'B', 'C', etc.
I need to know either
1)how to set this up correctly in the first place or
2)how I can reset the columns manually.
I have tried adding the table 2 ways..as follows...but neither one gets the headers right:
JScrollPane jScrollPane = new javax.swing.JScrollPane(getTable());or
JScrollPane jScrollPane.setViewportView(getTable());Note: getTable()..is where the new javax.swing.JTabel(new TableModel())stuff is done.
thx, ESWYou mentioned the you columnNames array. I suggest you declare it as static and accessible from within your custom table modelprivate static final String[] COLUMN_NAMES = {"John", "Janet", "Jamie", "Jennifer"};Then you override/implement the following methods in your TableModel :public String getColumnName(int column) {
return COLUMN_NAMES[column];
public int getColumnCount() {
return COLUMN_NAMES.length;
}That should do the trick. -

The best thing might be to SET PAGESIZE 0, which turns off paging. Unfortunately, that turns off the automatic headers, too, so you'll have to supply your own header, manually, like this:

Sorting a Collection with dynamic columns using a custom compare function for multiple columns
I need help and ideas on how to sort a ListCollectionView. My problem is complicated by 3 requirements-
1. The column values contain HTML tags that needs to be removed before sorting (use custom compareFunction to strip HTML)
2. The columns are dynamic, so dataField names are not known at compile time (need a single compareFunction for all columns)
3. The data is used in an AdvancedDataGrid so multi-column sorting is required
I have figured out how to solve any 2 of the 3 requirements. However, I am having difficulties supporting all 3 requirements.
Any help or ideas would be greatly appreciated. Thanks.After playing with this some more I think I've figured out a solution. This seems to work in initial testing. Also, there is not a need to capture the current sort column in the headerRelease event which many offered solutions suggested. Another benefit to this solution is that keyboard initiated sorting is handled also. Whereas the headerRelease event is only triggered by a mouse click on the column header and special handling is required if the user uses the keyboard to access the column header.
One point that I don't understand is how ascending/decending order is determined. Behavior seems to be different between a single SortField versus multiple SortFields. Notice how the compareResults are handled for the different situations. Anyone out there know why???
private function colSortCompareFunction(obj1:Object, obj2:Object, fields:Array = null):int{
var compareResults:int = 0;
var newObj1:Object = new Object();
var newObj2:Object = new Object();
// should not be a condition that is met
if (_dataProviderDetails.sort.fields == null) {
var s:Sort = new Sort();
var f:Function = s.compareFunction;
return f.call(null, obj1, obj2, fields); }
// when a single column is selected for sorting
else if (_dataProviderDetails.sort.fields.length == 1) {
var firstFld:SortField = _dataProviderDetails.sort.fields[0];

if (compareResults != 0) {
if (fld.descending) {
return compareResults * -1; }
else {
return compareResults; }
return compareResults; }
Does anyone see any problems with this solution?
NOTE: stripHTML(String) is a simple function using regular expression to remove HTML tags.
Thx
