DataGrid header functionality to manipulate column data

I have been displaying information for individual series in a chart via a datagrid so that the user can edit it (change color, series style, etc.) And it works fine, but now I need to add in some functionality in the header of the series style column. Basically the user needs to be able to "override" each entry to make all of the series types lines or area or plot or whatever he chooses in the header. In my research on the net, it looks like I may have to use AdvancedDataGrid to do this. Does anyone know how I would do this.
Here's what I have so far. I've left out most of the other columns for simplicity.
<mx:DataGrid id="seriesTable" color="black" fontSize="9" rowHeight="30" editable="true" resizeEffect="slow" rollOverColor="#CCCCCC"
selectionColor="#999999" dataProvider="{axis.seriesList}" width="100%"
rowCount="{axis.seriesList.length > 2 ? axis.seriesList.length : 2}" >
<mx:columns>
         <mx:DataGridColumn width="40" dataField="color" headerText="Color" id="colorColumn"
                    rendererIsEditor="true" editorDataField="result" itemRenderer="renderer.ColorPickerRenderer"/>
         <mx:DataGridColumn dataField="plotType" width="220" id="plotColumn"
                   rendererIsEditor="true" editorDataField="result" itemRenderer="renderer.TypeBoxRenderer"/>
      </mx:columns>
</mx:DataGrid>
(I could also include TypeBoxRender code but I don't think it's really needed to understand what is going on here.)

Fetching column data for clicked DataGrid cell

I am using a DataGrid and the number of columns are based on the data thus dynamic; columns are added at runtime. I am trying to use the same ItemRenderer for all columns. The one piece I can not seem to get to work is knowing which datafield to use to populate each column. I have tried getting the column.dataField from the current datacolumn to no avail; sample code listed below. This is my first Flex project so my approach to the problem may not be the best; please alert me if this is the case. I would appreciate any help you could lend.
                var dgListData:DataGridListData = listData as DataGridListData;
                var dataGrid:DataGrid = dgListData.owner as DataGrid;
                var column:DataGridColumn = dataGrid.columns[dgListData.columnIndex];
                var dataField = column.dataField;
                var lbl:Label = new Label();
                lbl.text = value[dataField];    // must add based on previously named source field; dataField

Update:
     A few more details...
I am trying to do this inside of override public function set data(value:Object):void {}

How to swap column-data along with Table header

Hi All!
I found a smple JTableDemo.java class. When I run it it provided sorting on the table as well as Dragging Column-data along with Table header while swaping two columns-headers.
I designed my own table and apply some changes to TableModel. Afterwords it swaps Table-Headers only, but not their respective columns.
Can someone give me a clue for that, where the logical error may be?
Thanx in Advance

surprised.. since you have asked, it must have some more tricky issue. Any way what i thought of it
in before insert on table2
simply insert into table1 (cr_id) values (:new.cr_id_id);
i assume that table1 pk does not generated through sequence
proposed insertion will not violate the uniqueness and create another record only in table1
what is thehidden agenda for not using simple before insert trigger as above.

How to ensure header and column data are aligned using JTable

We have a JTable but it looks like header cells are a bit misaligned from table column data. How can this be fixed?

I asked you a question in your previous posting on the exact same subject and you never replied. Why should i bother again?

Manipulate BLOB column data

Hi,
I've database Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
I need help on manipulating BLOB column data. It is storing .msg file. I want to modify its 'Subject:' line. Below query gives me position of Subject line but when I'm trying to read its content before modifying it then it is giving me error as ORA-06502: PL/SQL: numeric or value error: raw variable length too long:
SELECT dbms_lob.substr(case_content, dbms_lob.instr( blob_column, utl_raw.cast_to_raw('Subject')),50)
FROM my_table
But below query gives me position properly:
SELECT dbms_lob.instr( blob_column,utl_raw.cast_to_raw('Subject'))
FROM my_table
Thanks in advance.
Regards,
Chintan

Firstly I would be wary of doing any string manipulation of binary data (.msg file). Secondly are you sure you have the parameters in dbms_lob.substr the correct way round: http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/d_lob.htm#i999349 You are getting the substring of case_content, starting with an offset of 50 and taking n bytes/chars where n is the postion of hte first occurence of "Subject" in case_content.

I want to customise the printed header to show the date but not the time. Is there a list of control words available to the custom header function?

The Date/Time option for header set-up shows both date and time. I only want to show the date

Hi Santosh Sutar,
Did you mean that you want to hide/show the rows in an worksheet? If I understood correctly, there is no such API in apps for Office at present. Most of functions are used interop with data.
If you want apps for Office to support this function, I suggest that you submit the feedback from link below:

And you get learn more about apps for developing from link below:

Hi,
you can check the view source of html and check the onclick code written on that plus sign(Expand All), just copy that onclick javascript code and put it on page javascript event.

Remove Flex DataGrid Heading Rollover Color

Hi,
How can i stop rollover color change in Flex 3 DataGrid heading ?
Can i override the following mehtod if yes how can i do this ?
drawHeaderIndicator(s, r.x, 0, visibleColumns[i].width, cachedHeaderHeight - 0.5, getStyle("rollOverColor"), r);
Thanks,
-Shrban

To do what you want to do requires a fair amount of work as the rollover color is set as a style, you can change the color but it seems the rollover can't be disabled(not without a custom datagrid).
A quick fix is to try and at least reduce the difference in the rollover color, this could be done as per below, which basically makes the rollover color the same as the lighter shade of the header gradient.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" minWidth="955" minHeight="600" creationComplete="appHandler(event)">
<mx:Script>
<![CDATA[
import mx.controls.Label;
import mx.events.FlexEvent;
protected function appHandler(event:FlexEvent):void
var colors:Array = dg.getStyle("headerColors");
dg.setStyle("rollOverColor",colors[0]);
]]>
</mx:Script>
<mx:DataGrid id="dg" x="234" y="198" width="619" height="360">
<mx:columns>
<mx:DataGridColumn headerText="Column 1" dataField="col1" />

Add categories to DataGrid header

Is there a simple way to add categories to the DataGrid header? Basically, instead of just a single row with headers, I want an additional row that sits above that row and describes sections of the grid (rather than individual columns). E.g., in html, I could do something like this:
<table>
    <tr><th colspan="2">Name</th><th colspan="2">Data</th></tr>
    <tr><th>first</th><th>last</th><th>age</th><th>gender</th></tr>
    <tr><td>john</td><td>doe</td><td>26</td><td>male</td></tr>
</table>
Is there a reasonable way to do something like that in Flex? I've looked at Alex Harui's DataGrid footer, but after playing around with it a bit, it doesn't seem that it would be easily adapated.

So I'm trying to generalize this to more than two subcolumns. I got the item renderer working fine, but when I include the modified SplitDataGridHeader as a custom header renderer, it fubars the whole grid (even the other columns). I assume something I'm doing is making the Player very unhappy, but I don't see any errors when debugging in FlexBuilder: the entire Grid just shows up as plain white, with no styles applied and no data at all (even for the columns using standard renderers). Any idea what could be causing issues like this?

HOW TO: Add /manipulate columns for a GridControl

HOW TO: Add /manipulate columns for a GridControl when the columns (attributes) are from different entity objects.
This HOWTO describes the basic steps of using attributes from different entity objects for a GridControl.
One way you can create a GridControl which contain attributes from different entity objects is to create a view object and base it on the entity objects which contain
the desired attributes.
Here are the basic steps:
1.Create a new view object (or use an existing view object) by selecting File>New from the menu, clicking the Business Components tab and double-clicking
on the View Object icon.
2.In the View Object wizard change the name to something meaningful.
3.Select the entity objects you will base your view object on.
4.Nivigate to the attribute screen and select the attributes you would like to include in your view object from each entity object. At this point you can also create
a new attribute by clicking the "New" button. The new attribute can be a concatenation of other attributes, derived from a calculation etc.
5.In the query panel of the View Object wizard, click "Expert mode" and enter a query statement. You write complex queries such as decoding a set of attribute
values.
6.Add your newly to your newly created view object to the application module by double-clicking on the application module in the navigation pane and selecting
your view object from the list.
7.Create a new row set.
8.Bind row set to a query by editing their queryinfo property and selecting your view object and its attributes from the queryInfo pane.
9.Create a GridControl and bind it to the row set by editing the dataItemName property of the GridControl. Since the GridControl is bound at the row set level
all of the related attributes are automatically added.

Michael,
Are you intending this as a commercial solution or a work around?
To take an existing equivalent, one would build a view in the database tailored for each grid in an Oracle Forms application. Or a separate query layered over tables for each form/grid in a Delphi or Access application? Even if it is ninety nine percent the same over half a dozen forms/grids?
And now you've added a whole slew of "slightly different" rowSetInfos to maintain.
So if you wanted to add a column that needs to appear everywhere... you've just increased the workload multi-fold?
That would be a management nightmare, wouldn't it? Not to mention yet more performance cost and a slower system?
Hmmmm..... I'm not sure I like where this is headed... someone needs to do some convincing...

How to copy complete column data of a table control similar to ALV

Hi All,
I have a senario where i need to select one column of a Table control and press Ctrlc then the complete column details should be copied and be able to paste it in another colum using ctrlv.
please suggest me how can i copy the complete column data similar to ALV .
Thanks in advance .
Edited by: ravi kumar on Sep 13, 2011 2:53 PM

Dear Ravi
I'm afraid there is no standard functionality for copy paste in ALV.
You would need to develop something to achieve that - a button for example.
Kind Regards
