Disable few rows in datagrid.

Hi,
I want to disable some rows(no rollover color, no selection) in datagrid. For example if have 10 rows i may need to disable 3 or 4 based on some flag.
Any idea?

Hi Moorthi,
Found Alex Harui’s excellent entry on 'Disabling List Selection' - http://blogs.adobe.com/aharui/2007/06/disabling_list_selection.html.
Same concept could be applied for datagrid selection.
Thanks and Regards,

Enabled/Disabled color row Datagrid

Hi all,
I extend class Datagrid to draw rows depending a value.
package comp
     import flash.display.Sprite;
     import mx.controls.DataGrid;
     import mx.core.Application;
     public class DataGridEx extends DataGrid
          public var rowColorFunction:Function;
          public function DataGridEx()
               super();
          override protected function drawRowBackground(s:Sprite, rowIndex:int, y:Number, height:Number, color:uint, dataIndex:int):void
               if ( rowColorFunction != null && dataProvider != null ){
                    var item:Object;
                    if (dataIndex < dataProvider.length){
                         item = dataProvider[dataIndex];
                    if (item){
                         color = rowColorFunction(item,rowIndex,dataIndex,color);
               super.drawRowBackground(s,rowIndex,y,height,color,dataIndex);
In MXML i wrote this. My purpose is user could chosse if the rows are coloured or not.
          private function colorRow():void{
               if (colorRowByFile == false){
                    colorRowByFile = true;
               if (colorRowByFile == true){
                    colorRowByFile = false;
And finally the code of Datagrid and color:
public function calcRowColor(item:Object, rowIndex:int, dataIndex:int, color:uint):uint
               if(item.numFile == 1)
                    return 0x49FFAD;
               if(item.numFile == 2)
                    return 0x33CCFF;
               if(item.numFile == 3)
                    return 0xFFCC66;
               if(item.numFile == 4)
                    return 0xFFFF99;
               if(item.numFile == 5)
                    return 0xFF6633;
               if(item.numFile == 6)
                    return 0xFFCCCC;
               if(item.numFile == 7)
                    return 0x996600;
               if(item.numFile == 8)
                    return 0xCCFF99;
               else return 0xFFFFFF;
<comp:DataGridEx id="dg_events" width="100%" height="100%"

</comp:columns>
</comp:DataGridEx>
The problem is:
Initially the option are enabled so the rows are correctly coloured depending the value of column numFile. When user clicks to disabled colors, datagrid appears correct (with no color) but if we click again to recoloured row the datagrid still the same state (with no colour).
I dont know the reason.
Thanks in advanced.

PD: sorry for my english

Does your override of drawRowBackground get called? Maybe the DG doesn't think it is dirty. There are APIs like invalidateList() that might help

Grey out(disable) a row in ALV grid

Hi,
I want to know how to grey out(disable) row wise in ALV grid display.
i..e.. Few rows in ALV grid display shoud be editable and few rows non editable based on certain condition.
How do we do that....Please help.
Thanks in advance.

Hi,
Since fieldcatalog is used to modify coloum and not the row, the fieldcatalog would not solve the problem.
Thankyou.

Read only set for few rows of a column in a table (not ALV)

Hi Gurus,
I have a table with multiple rows and columns. Under a particular column, I have to make few rows as read only, few rows as editable based on a coondition. How can I achieve this. I know how to make the whole column as editable or read only. But I'm not able to achieve few rows in a particular column as editable and few read only. Please give me more detail code.
Appreciate your help.
Regards,
David.

Hello,
That you can achieve by creating an attribute isReadOnly of type WDY_BOOLEAN in the context node that you bind to the TABLE. And set isReadOnly attribute based on your condition whether to set readonly or editable for all the context elements.
And in the layout view, for the column which has to be made readOnly or editable, bind the property readOnly to the context attribute isReadOnly.
When you run application, you will see the column as readOnly if the attribute was set to true and editable if it was set to false.
Hope this helps!

How can I control the display of rows in datagrid without changing the dataprovider?

Hello,
I'm using advancedatagrid to render my table but I'm facing a problem to skip few rows which are unwanted or to hide. I should retain my original dataprovider without any modifications to achive this behaviour as I'm using it at many places.
Can you guys please send me a tip or the example code? I really appreciate for it.
Thanks,
Siva.

Hello Gaurav,
Thank You..!!! I tried appling filterFunction on the ADG and got whatever I expected but filter changes the original dataprovider behaviour. SO which I dont want to do it.
I have created a local variable and binded whatever data wanted to display on that page. Infact it works as expexted and I still have original data provider as well.
I have one more problem, I'm using creationComplete to initialize my local data provider value. It works only once while creation of state. If I navigate my screens fore and back and come back to this screen, it doesn't display the modified values as creationComplete loads only while state creation.
Is there any mothid which does the samething while vising the page every time than creation?
Thanks,
Siva

You can do it using workaround ....:)

Disable few record in a table control not all records

Hi
I have an internal table of   6 rows with table control .first field char 1 (ws_flag) which I am using for line selection of row in the table control .
I have to disable some rows in a table control (user can not select or deselect it).
I dont want to disable all rows . I just want to disable some rows depending upon the condition .
Loop at screen doesnt seem to be working .
I already tried the below given code . how does Screen-name = column name this will besatisfied in a table control.
Set screen attributes for table control
loop at zzhb6_0100 with control zhb6ctl
                    cursor zhb6ctl-top_line.
    module modify_screen_0100.
endloop.
Then:
module modify_screen_0100 output.
loop at screen.
    if screen-name = 'ZZHB6_SAL_PHASE2_S-ZZMERIT_AMT'.
      if zzhb6_sal_phase2_s-zzself_funded = 'X' or
         zzhb6_sal_phase2_s-zzmed_rec     = 'X' or
         zzhb6_sal_phase2_s-zztr          = 'X'.
        screen-input = '0'.                       "Display
        modify screen.
      endif.
    endif.
    if screen-name = 'ZZHB6_SAL_PHASE2_S-ZZMERIT_AMT_SP'.
      if zzhb6_sal_phase2_s-zzself_funded = 'X'.
        screen-input = '0'.                       "Display
        modify screen.
      endif.
    endif.
endloop.

When using table control, chances are you have some code like this in the screen flow logic of the screen.
PROCESS BEFORE OUTPUT.
* PBO FLOW LOGIC FOR TABLECONTROL 'I_WOODCAPCON'
* MODULE I_WOODCAPCON_CHANGE_TC_ATTR.
* MODULE I_WOODCAPCON_CHANGE_COL_ATTR.
LOOP AT   I_WOODCAP
       WITH CONTROL I_WOODCAPCON
       CURSOR I_WOODCAPCON-CURRENT_LINE.
    MODULE I_WOODCAPCON_CHANGE_FIELD_ATTR.
ENDLOOP.
MODULE STATUS_0300.
Notice the MODULE I_WOODCAPCON_CHANGE_FIELD_ATTR. in the above code, this is the module which will allow you to change the attributes of the cell per row. Notice that this MODULE is inside the LOOP statement in the PBO flow logic.
So here is the coding for the module.
module i_woodcapcon_change_field_attr output.
modify i_woodcap index i_woodcapcon-current_line.
loop at screen.
    if i_woodcap-level = 'B'
      and screen-name = 'I_WOODCAP-PDATE'.
          screen-input = '0'.
    endif.
     modify screen.
endloop.
endmodule.
Notice here that my condition statest that if the LEVEL value for the row is "B", then I want to make the PDATE of the row "not ready for input".   'I_WOODCAP is the name of the internal table associated with the table control.
Help this helps.

Hi,
As Armin said use the following:
wdContext.nodeXXX().currentXXXElement().setAttributeValue("attributeName", value)
Here you give the value as value of simpleType and not its description.

How to Group Few Rows into One Rows In Query

Textinput in all the colums of the first row of datagrid

Hi
i need Textinput in all the colums of the first row of
datagrid.
can ayone tell me the solution..
Thx in advance.

This will not be easy. i see two possible solutions.
You could use a custom itemRenderer. This will require that
you find some way to identify the dataProvider collection index
from within the renderer, and set the renderer to editable when
that index is 0.
Or you could create a composite component using two
dataGrids, one with a single row for the editable columns. There
are examples available on combining two DGs this way.
Again, this will be difficult, so be sure that it is
absolutely required and consider some other UI approach if posible.

How do i just request a few rows returned?

Im using toad and working with a very large database, for testing purposes i just want to look at a few rows of results from my query. I thought it was SELECT MAX_ROWS(30) ..... but nope. Whats the sql command to just return a few rows from the query? Thanks for any help.

1) Note that without an ORDER BY, there is no guarantee that these two select statements would return any overlapping rows. And there is no guarantee that changing your filter conditions would give you different rows. It would be perfectly valid for
select * from emp e where rownum <= 20
Minus
select * from emp e where rownum <= 10to return 20 rows. Or 10 rows. Or 13 rows. And those may be the same rows as would be returned by the query
select * from emp e where rownum <= 100
Minus
select * from emp e where rownum <= 902) If you do introduce the ORDER BY that would be required to ensure that the two queries return overlapping rows, you'd have to add an extra layer of nesting since ROWNUM is applied before rows are ordered. So that would give you something like
select * from (
    select * from emp e order by empno
) where rownum <= 20
Minus
select * from (
    select * from emp e order by empno
) where rownum <= 103) Once you've made it that far, it's going to be more efficient to do something like
select *
from (
    select a.*, rownum rn
      from (select * from emp e order by empno) a
     where rownum <= 20
where rn > 10if you want a window of 10 rows.

Add new rows in datagrid flex 4?

need to insert some values of sliders, positions to datagrid in flex 4. Then i'll save those values in MySql.
All the values are overwriting on the first row of datagrid, how to insert new rows? I tried addItemAt() but did not work.
databaseData.addItem({distortion:"X " + a, originalimage:"4 * 4", w2simage: "4 * " + a, brainimage: "4 *"+ a, transformw2s: " ",transformbrainimage:""});

Check weather you add the new items with the same collection binding with your datagrid. Or else check the collection has been re-initialized before you add new item in that collection.

How to disable some rows in a matrix

Hi experts
I have a matrix
i want to do set line/rows disable and can't edit in rows
please post example code
thank you

As far as I know there is no direct way to do this - you can only set columns editable or non-editable.
A workaround could be:
catch the "got_focus" event on the beforeaction=true; check if it is your matrix (pVal.ItemUID) and if it is your row that you want disabled (pVal.row) - if it is, set bubbleevent = false to stop it (and maybe display a status bar message to users so they don't think its a bug)
Additionally for a visual clue, maybe put some sort of field at the start of the row that says "open" or "closed" or something, this way the user wont be confused when they cant enter the row.
If got focus doesn't work properly (I havent tested) maybe try some other event like click or keypressed.

Disable few rows in datagrid.
