RE: [flexcoders] Populating values in datagrid from arrays

Title: Message

As Kelly says, just do:

specdata_arr=itemSpecVO1.colSpecData

And then use a labelFunction instead of the columnName.

The problem is that when your getdata() function executes you set specdata_arr equal to a single value instead of an array then you repeat that step 4 times.

Also, unless your array has a column called ‘A’ and another one called ‘B’ its not going to display anything even if you set it correctly.

Hi,

I type casted the result as you have suggested here. But still my datagrid does not display the values.

import classes.ItemSpecVO;

var itemSpecVO:ItemSpecVO;
var myArray:Array;
var itemSpecVO1:ItemSpecVO;
var specdata_arr;

function getdata(result)
{
mx.controls.Alert.show("inside getdata - len"+result.length);
myArray= mx.utils.ArrayUtil.toArray(result);
itemSpecVO=myArray[0];
mx.controls.Alert.show("d0: "+itemSpecVO.colSpecData[0]); -- prints value correctly
mx.controls.Alert.show("d1: "+itemSpecVO.colSpecData[1]); -- prints value correctly
itemSpecVO1=myArray[1];
mx.controls.Alert.show("d0: "+itemSpecVO1.colSpecData[0]); -- prints value correctly
mx.controls.Alert.show("d1: "+itemSpecVO1.colSpecData[1]); -- prints value correctly
specdata_arr=itemSpecVO.colSpecData[0];
specdata_arr=itemSpecVO.colSpecData[1];
specdata_arr=itemSpecVO1.colSpecData[0];
specdata_arr=itemSpecVO1.colSpecData[1];
}

<mx:RemoteObject id="itemDetailController" source="gov.bls.ppi.janus.repricing.manageitems.controllers.ItemDetailController" showBusyCursor="true">
<mx:method name="getColSpecData" result="getdata(event.result)">
              <mx:arguments>
      <arg1>{itemSid}</arg1>
       <arg2>{irMonth}</arg2>
       <arg3>{monthNo}</arg3>
  </mx:arguments>
  </mx:method>
</mx:RemoteObject>

<mx:VBox>
   <mx:DataGrid id="colSpec_dg" width="600" dataProvider="{specdata_arr}" textAlign="left" height="250" headerHeight="50" editable="true" >
     <mx:columns>
    <mx:Array>
      <mx:DataGridColumn headerText="A" columnName="A" width="50" textAlign="left"/>
      <mx:DataGridColumn headerText="B" columnName="B" width="100" textAlign="left"/>
    </mx:Array>
     </mx:columns>
   </mx:DataGrid>

</mx:VBox>

What could be the problem?

Thanks,

Shweta

Try casting the result to an Array ...

      myArray= mx.utils.ArrayUtil.toArray(event.result);

It worked for me in a similar case ..

Hi,

I am having problem populating values in my datagrid. From my mxml, I make
a
remote call to my controller which returns an array of ItemVOs.
ItemVO has one-dimensional integer array, containing values for columns in
each row in the datagrid. i.e. if my int array in ItemVO1 contains values
1,
2 and array in ItemVO2 contains values 3,4, then my datagrid should display

   1    2
   3    4
Instead the code below displays my datagrid as
1,2   1,2
3,4   3,4

Code:
<mx:RemoteObject id="itemDetailController"
source="controllers.ItemDetailController" showBusyCursor="true">
             <mx:method name="getColSpecData"
result="result_ColSpecData=event.result">
                                     <mx:arguments>
                         <arg1>{itemSid}</arg1>
                                     <arg2>{irMonth}</arg2>
                                     <arg3>{monthNo}</arg3>
                         </mx:arguments>
             </mx:method>
</mx:RemoteObject>
<mx:VBox>
               <mx:DataGrid id="colSpec_dg" width="600"
dataProvider="{result_ColSpecData}" textAlign="left" height="250"
headerHeight="50" editable="true" >
                 <mx:columns>
                           <mx:Array>
                             <mx:DataGridColumn headerText="A"
columnName="colSpecData" width="50" textAlign="left"/>
                             <mx:DataGridColumn headerText="B"
columnName="colSpecData" width="100" textAlign="left"/>
                           </mx:Array>
                 </mx:columns>
               </mx:DataGrid>

<mx:FormItem direction="horizontal" width="100%" height="30">
             <mx:Text text="value:" width="90"/><mx:Spacer height="63"/>
             <mx:Text id="tobEffIrm"
text="{itemDetailController.getColSpecData.result[0].colSpecData[0]}"
width="57"/><mx:Spacer height="63"/>
             <mx:Text id="tobEffIrm1"
text="{itemDetailController.getColSpecData.result[0].colSpecData[1]}"
width="57"/><mx:Spacer height="63"/>
             <mx:Text id="tobEffIrm2"
text="{itemDetailController.getColSpecData.result[1].colSpecData[0]}"
width="57"/><mx:Spacer height="63"/>
             <mx:Text id="tobEffIrm3"
text="{itemDetailController.getColSpecData.result[1].colSpecData[1]}"
width="57"/><mx:Spacer height="63"/>
</mx:FormItem>

If I replace colSpecData with colSpecData[0] and colSpecData[1], datagrid
does not show any values. But the text field displays values fine as 1 2 3
4.
I fail to understand why the dataprovider in the datagrid does not work
with
indexes specified. Can anybody please help me with this.

Thanks in advance,
Shweta
