Summary rows

I am new to Flex. I wasn't quite sure how to code summary
rows in actionscript. Could some take a look at my codes and help
me figure out why it doesn't work? I really appreciate it.
I need to display a fixed data in group row. That is, I don't
need to calculate the result to be displayed in group row.

"Note: Summary data is not supported for hierarchical data
represented by
the HierarchicalData class. You can only create summary data
for data
represented by the GroupingCollection class."
I couldn't get at your app, since I'm not going to upgrade to
Flash Player
10 just to help you (I think that change is far more
difficult to undo than
to do), but you might find that you can make a
GroupingCollection from your
XML just by casting it.

How can i create a grid with summary row

Hello Professionals,
I'm wondering how could i create a grid like the grid below, i want to create a grid with summary row,
i have tried to create it using collapsing but it didn't work as required.
Any suggestions?, i want to know just the starting point so i can make deep investigations.
Thanks in Advance,

Hi Karem,
this can be achieved by just assigning a datatable containing the data plus some formatting of grid. Meaning there is no feature for that.
The datatable can be filled manually or by sql query. Then you have to attach some events for updating the values ( validate after for gid item ).
A small example for a sql query showing last month quotations and orders with summary :
select 1 as Sort,cast(DocNum as varchar) as DocNum,DocTotal,convert(varchar, DocDate,104) from OQUT where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
UNION ALL
Select 2 as Sort,'Summary ( Quotation ) : ',sum(DocTotal), convert(varchar, DATEADD(month, -1, GETDATE()),104)+' - '+convert(varchar, GETDATE(),104) from OQUT where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
UNION ALL
select 3 as Sort,cast(DocNum as varchar) as DocNum,DocTotal,convert(varchar, DocDate,104) from ORDR where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
UNION ALL
Select 4 as Sort,'Summary ( Order ) : ',sum(DocTotal), convert(varchar, DATEADD(month, -1, GETDATE()),104)+' - '+convert(varchar, GETDATE(),104) from ORDR where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
ORDER by Sort

Using Previous function in summary rows?

Hi,
I have a requirment, where I have to use the value got in previous column in the summary row.
The scenario is as follows.
There are Product, Quantity on Hand , Order Type and Date column. I am using cross tab, As I have to use the details of columns for each date.
So date will be spreaded across table as there are more dates.
In summary column, I would like to do a calcuation for each date. And I should use the calculated amount on one date in the next date and the calcuation continues.
I am trying to use previous function, but its showing computation error.
I am attaching a excel sheet with a sample example for easy understanding.
The calculation which I used in summary row is avialble in formula section, when we select the column.
Thanks in Advance.
Regards
Gowtham

Hi BOCP,
Yes, I am trying to use this function in Summary after Break.
Sorry, I missed out attachment. And I didn't find a way to attach it.
Suresh,
I didn't find last() function in WebI Editor. I am using BO XI R2.
Thanks a lot.

Tabular form calculated summary row

Hopefully this may be a quick question with either a yes or a no
I have a tabular form with columns
Project Name , Wk1 , Wk2 , Wk3 etc ,
basically so PM's can track the hours against a project
I have used the sum checkboxes to create a summary row
but they also want a row that calculates how many hours remaining for each week under the week no cols , obviously subtracted ffrom the hours budget for each week assigned to the project and person
I've done the summary and calculation in a view but this isn't acceptable as a UNION query in a tabular form
I've also tried another region under the Tabular form but as the project name is a variable length its not easy keeping the Wk cols aligned
thanks in advance
Chris

Hi Gus/Paul,
I had the same requirements as you, resulting from the fact that newly added rows may not be visible to the user until he/she has scrolled down sufficiently, but, by lowering my standards (something I excel at :D ), I was able to find an acceptable compromise.
As you probably noticed yourselves, when you "edit" the ADD button, you can see that a call is made to the addRow() javascript function. I therefore took a look at the javascript code - foolish really as I am an oracle DBA from the Jurassic period. Needless to say it scared the pants off me... So, fuelled by cowardice, I snatched at an inferior-but-dead-easy-to-implement alternative solution whereby the page is automatically "scrolled" to the bottom of the form when the "ADD" button is clicked.
Should this "cop out" work for you, you can implement it in the following way:
1. Create a new HTML region immediately after the tabular form, containing the following source: <a name="bottom_of_page"></a>
2. Amend the action when the "ADD" button is clicked to scroll down to the new region by doing the following:
- edit "ADD" button
- Go to "Action when button Clicked" section
- Amend "URL Target" from
Javascript:addRow();
 to
Javascript:addRow();window.location='#bottom_of_page'

Adding a dynamic summary row for a spark data grid

i'm looking for a solution for a spark data grid.
by clicking on a row it will become larger and will show under the original row a some kind of a summary text with no realtion to columns.
is there a summary row option for a spark datagrid that can shown by clicking on the row?

Why would you need to make this part of the DataGrid? Just create some kind of view and bind it's data to the selectedItem of the DataGrid.
*edit*
Ohhhh, I see that you want it to display under the item. I believe you can do what you need in the skin, but I haven't had a chance to use the spark DataGrid yet so I can't say for sure. I know it has a feature to skin the selection, so I'm sure you can use that to do what you need.

Summary row in JTable

I have created a JTable with some information. I want to have the last row of the table as a summary row so I want it to stand out. How would I go about putting the text in the last row of the table in bold font?
Thanks for help!

I looked at this example, but I thought that while the structure of the tutorial is good, the code might not be so great. Take for example the number renderer class, I won't repeat it here (might violate copyright) but the setValue method gets a number instance each time it is invoked to render a cell. My understanding is that this is inefficient, as getting an instance is a fairly involved procedure (it involves looking up locale information for instance). Also the code makes heap allocations which could potentially overwhelm the garbage collector (from what I've read).
I'm learning java, and I used the example to make a decimal renderer. The main purpose of this is to show the number for the default locale and the specified number of decimal places:
import java.text.NumberFormat;
import java.text.DecimalFormat;
import javax.swing.table.DefaultTableCellRenderer;
public class DecimalRenderer extends DefaultTableCellRenderer {
    int precision = 0;   //my addition
    Number numberValue;   //moved from setValue()
    NumberFormat nf;   //moved from setValue()
    public DecimalRenderer(int p_precision) {
        super();   //same as example
        setHorizontalAlignment(javax.swing.SwingConstants.RIGHT); //same as example
        precision = p_precision; //my addition
        nf = NumberFormat.getNumberInstance(); // moved from setValue
        nf.setMinimumFractionDigits(p_precision); // my addition
        nf.setMaximumFractionDigits(p_precision); // my addition
    public void setValue(Object value) {
      if ((value != null) && (value instanceof Number)) {
        numberValue = (Number) value;   // re-use the class member, not a local member
        value = nf.format(numberValue.doubleValue()); // same as example
      super.setValue(value);
} By re-using the number instance and making the variables class level fields as opposed to local members of the setValue function, I expect to avoid the problems I mentioned above.
Have I understood the situation correctly? I guess that experienced people would be aware of this, but I get annoyed by the examples I see as they typically give 'expedient' examples which seldom represent 'best practice'. Often, I can see that something probably isn't best practice, but I don't know what the best practice is.

Advanced Datagrid - Summary Row without groupping

I need to make a datagrid with a summary row on top of it. It
works fine with the gropping tag inside of groupping collection.
But i don't need groups - i need only summaries.
When I white following code inside of Advanced - flex crashes
and tell something like "cannot null blablala".
quote:
<mx:GroupingCollection id="smallMetricsDataProvider"
source="{bigMetrics}">
<mx:summaries>
<mx:SummaryRow summaryPlacement="first">
<mx:SummaryField dataField="@type" operation="COUNT"
/>
<mx:SummaryField dataField="@budget"
summaryFunction="MetricsUtils.varianceTotalCount" />
<mx:SummaryField dataField="@raw"
summaryFunction="MetricsUtils.varianceTotalCount" />
</mx:SummaryRow>
</mx:summaries>
</mx:GroupingCollection>
What can you advice 4 me?
Thanks, Roman.

Fine, I found a way how to do it, using renderprovider 4
folder items with a null height =))).
It's a hack, the bad hack, i hope it wold be improved...
So, i have another problem - i want to get this summary
values. How?
Thanks, Roman.

In a ADG is it possible to have a pie chart in a summary row?

In a ADG is it possible to have a pie chart in a summary row?
The segments would be worked out from a funtion applied to the data
in that grouping.
Thanks :)

The JTable is a tabular component. So it will always have enough columns to display the maximum row length. you don't have to pur a value in every cell.
There are methods in JTable to remove horizontal and vertical lines and you could implement a renderer to make empty cells look like the background.

Summary row in tableview (including sorting and BYPAGE navigation)

Hello everybody,
I already found a few topics dealing with this problem but I wasn't able to find a real solution for this.
So far I'm pretty familiar with table iterators but I have no idea how to handle the summary row to be the last line in a table, even if sorting and navigation by page is allowed in the tableview.
I think you definitely have to add this summary row in your internal table, since you can not add a virtual row in your tableview. And you can custom render this row or respectively each cell for instance with a different color but how to force this row always to appear as the last row in every tableview page (navigation=BYPAGE).
Does anyone have a solution for that?
Thanx
Oliver

Ok, here is what I came up with (hoping I got your problem right):
In your tableview you are displaying x rows, and after these rows you want your sum row to be displayed.
I have done quite some things with iterators, but why not do without one here
Altering the internal table can do as well:
Try to insert a new row after every x rows into your internal table which holds the needed sum values, and then change your tableview to display x+1 rows.
In you case you need to do some operations with your internal table (to avoid the sum rows messing up the results) you should somehow "mark" these sum rows so you can distinguish them later on.
Hope this is helpful for your problem.

Rank only summary rows from group by rollup

I would like to rank only the total rows generated by a group by rollup, but not rank the rows within each group by bucket. Furthermore, I'd like to order by rank in descending order and include the unranked rows within each group.
My query looks something like this:
select customer, month, sum (sell)
from sales
group by rollup (customer, month)
order by customer, month desc nulls first
The results look like:
customer month sum(sell)
<summary rowA> 1,200
custA JAN 100
custA FEB 100
custA MAR 100
custA DEC 100
<summary rowB> 600
custB JAN 50
custB FEB 50
custB MAR 50
custB DEC 50
What I would like to do is:
select dense_rank() over (order by sum(sell) desc <rollup rows only>) as rank,
 customer, month, sum (sell)
from sales
group by rollup (customer, month)
order by <summary row rank desc> customer, month desc nulls first
The results would look like:
rank customer month sum(sell)
1 <summary rowA> 1,200
 custA JAN 100
 custA FEB 100
 custA MAR 100
 custA DEC 100
2 <summary rowB> 600
 custB JAN 50
 custB FEB 50
 custB MAR 50
 custB DEC 50
Any advice?
Thank you

Like this?

JTable Header/summary Row

Hi
I have a jtable and I want to add a summary row right under the header. I added a row and I specified in the sorting class to start from 1 instead of 0, which made my summary not sortable. but, when I scroll down, the summary row disappears.
How can I make it not disappear? the same problem with printing. I'm using the table.print method and it prints only in the first page, while I want to print on every page.
I think I should add it as part of the header? I have no idea how to do that.
any ideas or help?
Thanks,
Benbak

Style AdvancedDataGrid Summary Rows

I have an AdvancedDataGrid with summary rows. Everything works fine, but the user wants the summary rows bolded, so the totals stand out even when the categories are expanded. There don't seem to be any style properties, itemRenderers, or labelFunctions associated with any level of a GroupingCollection. How can I do this?
Thanks.
-John

I figured it out, so here it is for posterity:
I had to use the AdvancedDataGridColumn's styleFunction, and test the row object for a "GroupLabel" property. If it exists, bold the row, like below:
          protected function boldSummaryRows(row:Object, column:AdvancedDataGridColumn):Object {
                var styleObject:Object = new Object;
                if(row.hasOwnProperty('GroupLabel'))
                    styleObject.fontWeight = 'bold';
                return styleObject;

Customizing summary row AdvancedDatagrid

i want to customise the look and feel of the summaryRow of the AdvancedDatagrid by including borders to the top and the bottom.I tried overriding createChildren() and adding HRule as the first and last child of the summaryRenderer.The HRule is getting added but it is not getting displayed.Am i doing somthing wrong.If so how can i customize the look and feel .Please suggest

You can just use Renderer providers to customize your SummaryRow just like you use Renderer Providers for your columns.Specify the label name of the summary row that you want to customize in the renderer provider.

ADG summary row children count

Hi all
Can anyone please tell me the best way to include a count of direct children in a grouping collection summary row? My data has two grouping fields and I can use a summaryfield to get a count of ALL children from depths 2 and 3 but I only want the direct children from the next level down.
Hope that makes sense.
Thanks
Dustin

Managed to find a resolution to this myself. Although not in the summary row itself, I was able to use this in my group item renderer...
{this.parentDocument.myAdvancedDataGrid.hierarchicalCollectionView.getChildren(data).lengt h}
