Hi..

I am using web service to fill a grid, in the web method i have to pass two
parameters, it will return result of xml document. The same i want to fill in a
DataGrid using Flex.

Please help me..its urgent

Hi,
This is very easy. Send a httpservice with the two parameters to the backend
which gives back an xml document. You can use that as the dataprovider of the
grid.
In case you want further details post the sample xml code and i can post a
detailed code as to how to do this . also mention the backend u r using..

Hi,
Thank you for reply..but i want to use web service instead of http service.
Sending you the sample code..please work on that and help me in binding to the
grid.

After login..i want to fill the result in the datagrid

Help me in doing the same
thanks in advance

I am using SQL as backend. This is called by webservice

Looks like you are using ASP.NET
Dumb question: Does your web service method accept parameters?

Yes..i am using ASP.Net
Fine with the question, but its taking the parameters.

Only problem is to show result in the grid.
Please go to the code, which i worked on.

Thanks in advance

I understand.

1) In GetloggedInUserList_result, get rid of the var "adgataGrid = new
DataGrid();". You already have the data grid declared in MXML so you don't need
to do this.
2) Instead of "dg.dataProvider= event.result.toString();"... (btw your
datagrid's id is "adg", NOT "dg")...
... try adg.dataProvider= S1.GetloggedInUserList.lastResult;

I can't see the data you are returning, but this should get you started in the
right direction.
Remember you can always examine the returned data and see how to assign it to
the datagrid's dataprovider property.

we are getting variable not found error. and our data returns from web service is in xml format. Is any process to convert xml to any format and then bind to datagrid?

Check your returned data to see how it is formatted. XML format is fine to use for a datagrid.
