Item renderer for specific rows

I need to have a checkbox item renderer for a spark datagrid column. I am using the following to get an item renderer into column:
var checkBoxRenderer:ClassFactory = new ClassFactory(GridCheckBoxItemRenderer);
column.itemRenderer = checkBoxRenderer;
My question is if I need to show a checkbox for specific rows can I do that without going into GridCheckBoxItemRenderer's source code?
Thanks

Hi,
I think your requirement can be completed by using ViewStack you can pass selected index to it according to requirement.
See:
<itemRenederer ...
     <viewstack selectedIndex = 0 ...>
          <vBox id="vBox1" >
                    Your 1st itemrenderer will come here....
          </vBox>
          <vBox id="vBox2" >
                    Your 2nd itemrenderer will come here....
          </vBox>
     </viewStack>
</itemRenederer>
You have to just toggle selectedIndex.
Thanks

Item Renderer for DataGrid

I have a button component as a Item renderer in the column of
the datagrid .
I am not able to access the Itemrenderer component(which I
declared in other mxml file in the datagrid)
This is the data grid where I have the Itemrenderer:
<mx:DataGrid id="dgCondition1"
variableRowHeight="true" width="100%" height="150"
verticalScrollPolicy="auto" editable="true"
dataProvider="{initDataGrid_Create}" >
<mx:columns>
<mx:DataGridColumn headerText="" dataField="conditi"
/>
<mx:DataGridColumn headerText="Condition"
dataField="syntax" width="300" />
<mx:DataGridColumn headerText="1" dataField="value"
width="80" editable="false" itemRenderer="buttonRenderer"/>
<mx:DataGridColumn dataField="value" headerText="2"
itemRenderer="buttonRenderer" />
I created a new mxml component for this button component
.(buttonRenderer.mxml)
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="
http://www.adobe.com/2006/mxml"
width="400" height="300">
<mx:Script source="..TableDataGridBtn.as" />
<mx:Button id="col1" label="" width="75"
click="getDetail(event,col1)" />
</mx:VBox>
The Problem is I am not able to access the buttonRenderer in
the datagrid itemRenderer tag .
It says "Access of Undefined Property buttonRenderer".

Setting Table Cell Renderer for a row or cell

I need to make a JTable that has the following formats:
Row 1 = number with no decimals and columns
Row 2 = number with no decimals and columns
Row 3 = percent with 4 decimals
I can use a table cell renderer to set each COLUMN as one or the other formats like this:
NumDispRenderer ndr = new NumDispRenderer();
for(int i = 1;i<dates.size();i++) {
table.getColumnModel().getColumn(i).setCellRenderer(ndr);
Where NumDispRenderer is a class as follows:
public class NumDispRenderer extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent (JTable table, Object value,boolean isSelected, boolean isFocused, int row, int column) {
Component component = super.getTableCellRendererComponent (table,value,isSelected,isFocused,row,column);
if (value != null && value instanceof Double) {
DecimalFormat df = new DecimalFormat("###,###");
String output = df.format(value);
((JLabel)component).setText(output);
((JLabel)component).setHorizontalAlignment(JLabel.RIGHT);
} else {
((JLabel)component).setText(value == null ? "" : value.toString());
return component;
This is fine for the first two rows, but the third row (which is also an instance of Double) I would like to format differently.
The tutorial and other postings have not given a solution to this problem. Any suggestions would be very appreciated.

Hi,
the method getTableCellRendererComponent() of your renderer gets the row as a parameter. So just create the label depending on that value. For 0<=row<=1 you create the label as is, and for row=2 you create another label with the Double formatted as you wish.

Mass delete of PO item texts for specific PO and SA

Hi All,
I have thousands open PO's and SA's coming in during conversion in SAP system. For many of them we have material specifications and drawing number coming in from legacy and we populate them using standard BAPI create function module.
On the other hand we also have a BADI activated ME_PROCESS_PO_CUST which populates the PO item text 'spec details' from material master CLASSIFICATION and drawing number from BASIC DATA2.
We have a logic implemented saying if legacy file has a value in Material Specification it will not trigger the BADI, if the value is NULL it will trigger the BADI and fetch the data from Material Master.
But now we want to have the material specifications coming in from legacy as it is. If it has a value it will populate, if it is blank it will leave it blank.
My question is without a change around the BADI and PO create function module what are the ways to delete the item texts from the PO's and SA's for which legacy value is NULL. The deletion will be only for specific PO's, say out of 10000 PO line items posted in the system I want to delete Material Spec for 6000 of them. Appreciate your help in advance.

you have to write your selection logic in a small ABAP and then call the funcion module DELETE_TEXT

Generic item renderer for Adv DG Columns?

Hello,
I'm trying to create a generic ItemRenderer for my Adv DG so that so that I can put a toolTip on the cells.
The Adv DG Column object doesn't have a toolTip property so I'm creating my own renderer...
As far as I'm aware I have to create an ItemRenderer that knows the fieldName that it is rendering so I can use {data.myFieldName}. I was hoping there was a property so that I can reference the value generically such as {data.text} but this obvisouly doesn't work...
Is there anyway around this? Can I pass a paramater to the itemRenderer? I'm doing it like this...
advancedDataGridColumn.itemRenderer = new ClassFactory(renderers.ToolTipFieldRenderer);
Alsok, there is a toolTip property of the AdvDG but the columns, what is the AdvDG.toolTip used for? Just a general toolTip? The reason why I need a toolTip is our client has asked to be able to mouse-over the cell to see the full value where the field value is chopped because it's too long for the column...
Hope that makes sense and hope you can help...
Cheers,
Nick

The AdvancedDataGridColumn class has dataTipField and dataTipFunction
properties and these are supported by the default item renderer
(AdvancedDataGridItemRenderer), which is also generic. Here's an example:

                dataTipField="Album"
                showDataTips="true" />
            <mx:AdvancedDataGridColumn
                dataField="Price"

Info on cell editors for specific rows

Hi all,
Could anyone tell me how to return different components to be the editors for different rows in a table.
I have certain rows that will use a checkbox editor and certain rows that will use a formatted textfield editor. I have coded an outline to my custom editor which extends Component and implements TableCellEditor. Any help would be greatly appreciated.

Multi-Use Item Renderer for DataGrid Column

I have a dataGrid where the first column of the grid displays
an icon for the 'type' of item in the row. I created a custom
itemRenderer component which I reference in its own namespace, and
everything works great. Since this is a pretty common concept, I'd
thought that I'd be able to re-use that itemRenderer throughout the
application, but everytime I try to call the itemRenderer in
another dataGrid, I get 2 errors saying "the inlineComponent could
not be found" and then because of that "Access of undefined
property".
It doesn't make sense for an itemRenderer to be only good for
one use, so I'm obviously missing some fundamental issue. Can
someone enlighten me?

Hah, found it. It is an mxml example, and implements
IDropInListItemRenderer. It for an image renderer, but you will be
able to see what to do.

Cfinclude query: return result for specific row

I've been trying to crack this all day and I feel like if I
just had a nudge in the right direction I might be successful.
I have a query that returns the records for some textbooks
that are at a specific school. I've normalized the textbook
database so that the primary, secondary and tertiary subject
categories are represented by the primary key of that category in
its own table. As the query loops through the records, I want it to
return the (varchar) subject category that goes with that
(numerical) key in the table.
Since Coldfusion won't allow nested cfoutput, I've tried
using cfinclude to grab the specific name for the subject category
that goes with the current textbook - but what I've got so far
returns all the subjects for the school id in each row - they're
the right subjects! but I don't want all of them, just the right
one with the right book/record. Can anyone suggest what I need to
do? I'm attaching the code for the main page and for one of the
cfincludes (they're identical except for "primary", "secondary" and
"tertiary").
I realize I must be leaving something out but I can't figure
out what. Thanks much in advance.

Marianne,
Glad I could help. To meet your requirement it seems like you
would add one field to my schema in the Subjects table:
parentSubjectId number (FK)
That would simply be a recursive reference to another
subject's ID to which it falls under. Maybe that doesn't make sense
so here's some example data:
subjectId, subjectName, parentSubjectId
1, "Language Arts", null
2, "Reading", 1
3, "Phonics", 2
4, "Other Subject with no parent", null
So you can see we have built ourselves a nice hierarchy,
where subjects which fall under other subjects can reference them.
When you go to allow subjects to be chosen you can then query after
each drop-down selection by refreshing the page (or via AJAX) to
get its subjects. In this case we could also possibly do away with
the "Ranking" field in our linking table since our hierarchy is
captured in the relationships we now have, but for the sake of
making our lives easy, let's keep it.
Like let's say we select "Language arts" with a subjectId of
1, we can get its child subjects like:
<cfquery name="getChildSubjects"
datasource="#Request.dsn#">
SELECT s.subjectId, s.subjectName
FROM subjects s
WHERE s.parentSubjectId = <cfqueryparam
cfsqltype="cf_sql_integer" value="#URL.subjectId#" />
ORDER BY s.subjectName
</cfquery>
Obviously, modifications would need to be made to fit your
schema, variable names, etc. but that's the general principles.
As for how to associate textbooks to subjects you will
actually be inserting one record into the linking table for each
subject selected. So let's say you have a book "XSS for dummies."
To insert the book you would add a single record in your
textbook table, maybe something like:
INSERT INTO textbook (
textbookId,
textbookName,

) VALUES (
1,
'XSS for dummies',

Now, the user has selected three subjects: Computer Science
(ID: 5), Internet and Web Topics (ID: 11), and Security (ID:98). We
will thus insert three records into our linking table like:
INSERT INTO textbookSubjects (
textbookId,
subjectId,
ranking
) VALUES (
1,
5,
'Primary'
INSERT INTO textbookSubjects (
textbookId,
subjectId,
ranking
) VALUES (
1,
11,
'Secondary'
INSERT INTO textbookSubjects (
textbookId,
subjectId,
ranking
) VALUES (
1,
98,
'Tertiary'
So now when we query to get all our textbooks and related
subjects, we have something like this:
SELECT t.textbookId, t.textbookName, s.subjectId,
s.subjectName, ts.ranking
FROM textbook t
LEFT JOIN textbookSubjects ts
ON t.textbookId = ts.textbookId
LEFT JOIN subject s
ON t.subjectId = s.subjectId
ORDER BY t.textbookName
An example dataset might look like:
textbookId, textbookName, subjectId, subjectName, ranking
1, "XSS for Dummies", 5, "Computer Science", "Primary"
1, "XSS for Dummies", 11, "Internet and Web Topics",
"Secondary"
1, "XSS for Dummies", 98, "Security", "Tertiary"
2, "Some Other Book With No Subjects", null, null, null
Now if we iterate over this dataset, you will end up
outputting the textbook 3 times, which is probably not what you
wanted. So to control this we can do something like:
<cfoutput query="myBooks" group="textbookId">
<tr>
<td>#myBooks.textbookName#</td>

<td>

<cfoutput>
#myBooks.subjectName#<br />
</cfoutput>
</td>
</tr>
</cfoutput>
These examples are obviously brief but I hope they get the
point across and help you accomplish what you're trying to
do.

Designing the consolidated and line item report for specific material

Hi
i have a R/3-report and it run only for 7-materials.That means we need to only those 7-materials in the selection screen of report.
Then we will get each material corresponding line item details(material no, profit center, variable cost, quanity, price, financial loss(this is calculated based on quantity) , Utility Consumption(calculated based on price, variablecost) ) in one report.
Another report will give same for consolidated values of financial loss, utiliy consumption.
<b>so how can i design the consolidated and lineitem details report for each material.</b> pls let me know

0VENDOR_ATTR - Vendor Master Data Attributes
0FI_AP_51 - Check Register Line Items
0FI_AP_4 - Accounts Payable Line Items
It should be noted, however, that this won't get you everything that you need, so you may have to create enhance one or more of these DataSources and create User Exit ABAP code to get the required data. Also, the 0FI_AP_51 DataSource isn't available if your source system isn't ECC6 EHP3 or higher. If your source system is less than that, you're going to have to create a generic DataSource for the data from the PAYR table.

Encountering problems getting the median value for specific rows alone.

Consider the following columns:
Call Value
0.49

1.22
1.29
1.34
1.64
1.8
2.25
3.86
4.32
5.12
Median 1.64
Quartile 1
0.49
0.65
1.22
1.29
1.34
Expected Median 1.22
BO Returns
The first column in the table contains call values. The median of all the call values is 1.64. BO displays this value as is (correctly). In case of obtaining the median for Quartile 1, BO returns a null value instead of 1.22.
Can anyone please tell me what needs to be done in BO to achieve this value 1.22?

Hi Rajiv,
Following is the syntax of the formula for median values.
The Syntax is as follows:
number Median([measure]), where measure is any measure object.
Example
Median([Revenue]) returns 971000 if [Revenue] has the values 736431, 971000, and 5476652
Please note that the Median function in BusinessObjects works differently from the Median function in Microsoft Excel.
For odd number of rows in the report, the Median will take the middle value and for even number of rows in the report, the Median will take the two middle values and calculate the Average of them.

Item Renderer for Advance DataGrid

On AdvancedDataGrid, can we display one of the column as Text and when the user clicks on the text it should turns into a combo box.
When the user clicks on any where else it should turn into text back.
Please help me to implement this.

Off the top of my head it's probably something like:
<mx:DataGrid id="dg1" width="100%" height="100%">
<mx:columns>
<mx:DataGridColumn dataField="Example">
<mx:itemEditor>
<mx:Component>
<mx:ComboBox>
<mx:String>1</mx:String>
<mx:String>2</mx:String>
<mx:String>3</mx:String>
</mx:ComboBox>
</mx:Component>
</mx:itemEditor>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
edit:
Just checked, Subeesh's example: http://blog.flexmonkeypatches.com/2008/02/18/simple-datagrid-combobox-as-item-editor-examp le/ has got a very good example on it. Pretty much exactly what you asked

Using a canvas for item renderer

I have an array collection of objects. The class has a
function getDisplayObject which returns a canvas with all of the
components I need in it. I'd like to use that canvas directly as a
custom renderer for a combo box. How can I set the returned canvas
as the item renderer? I've made custom renderers, but not with a
canvas itself. I think I need to call getDisplayObject inside of
the item renderer for each object, but am not sure how. Thanks.
(Below is what I've tried, but this only adds the first one out of
an array of 5... hmm...)
