[EvelynHernandez]

Hey guys im trapped in this.
I want to fill a datagrid with values obtained from a featureset but i dont know how to get the parameters to put each one in the column that i want. Also the datagrid it is empty !!


Thanks for all the help.

//the Grid.  <mx:DataGrid  id="gridEquipos" x="2" y="5" width="100%" height="100%" visible="true" editable="false" dragEnabled="true" dropEnabled="true" dataProvider="{listaEquipos}" itemClick="gridEquipos_itemClickHandler(event)">                                                <mx:columns>                                                                <mx:DataGridColumn headerText="Código Equipo / Medidor" dataField="id_eq" id="IDEquipo"/>                                                                <mx:DataGridColumn headerText="Cant.

Yes i just tried and it doesnt work.
The grid is still in blank....

Also i tried making another grid but it doesnt work either.
Is there a way to know the attribute field's name to see if maybe it is that...
Thanks for ur patience!

Evelyn,

   You could trace out the results of featureSet.attributes using

trace(ObjectUtil.toString(featureSet.attributes));

[EvelynHernandez]

How can i see the trace results?
Because im using a trial version of FB.

[RobertScheitlin__GISP]

Evelyn,

   Trial version does not matter. When you debug your app using the "little green bug" button to the left of the green play button you will be able to see trace statements in the console window.

[EvelynHernandez]

rscheitlin,

It says this

C:\WINDOWS\system32\Macromed\Flash\NPSWF32_12_0_0_70.dll

Flash Builder cannot locate the required debugger version of Adobe Flash Player. You might need to install the debugger version of the Flash Player or reinstall Flash Builder.

Do you want to try to debug with the current version?

And if i run the debugger doesnt show anything.
And i dont know where the console is located.

[RobertScheitlin__GISP]

Evelyn,

  Don't take this the wrong way, but you need to invest some time reading, Googling, and leaning.

https://developers.arcgis.com/flex/guide/debugging-tips.htm

To be able to use the Flash Debugger you have to install the debugger version of Flash Player (look for the download link for your flavor of web browser):

http://www.adobe.com/support/flashplayer/downloads.html

To find the console window: Window menu > show view > console.

rscheitlin,

I finally did what i wanted to do with this
Attribute table. It is more easy.

https://developers.arcgis.com/flex/sample-code/attributetable.htm



The only problem that i have now is how to get the value of the cell what was clicked on the attribute table. Even if its the first one or second one.
Thanks.

[RobertScheitlin__GISP · Accepted solution]

Evelyn,

   I think you gave up to soon. Setting up your development environment is going to be very important if you are going to do very much with development in Flex. The trace statement and flash debugger version are great tools for any level of development and spending time getting them ready to use is important.

As far as get a selected cell value from the AttributeTable... I dont work with the Attribute table as it is so much easier for me to setup a spark datagrid. But here is what I think based on the docs:

var at:AttributeTable = new AttributeTable();                 at.dataGrid.selectedItem

[EvelynHernandez]

Well i just tried for last time the thing with the datagrid and now it works perfectly.
Really i dont know what happened before, but that makes me to do and learn a lot of new things about alternative ways to face a problem.

I really didnt understand about the trace and debugger and im still learning through googleing.

Thanks for all ur tips (:
