Below is the code. The only thing that I was missing was assigning datafeild and width. private function constructDynamicColumnForADG():void{ var colsArray:Array = new Array() ; var column:AdvancedDataGridColumn ; var res:Number = flash.system.Capabilities.screenResolutionX; for each(var domainObj: in domainObjList) { column = new AdvancedDataGridColumn() ; column.headerText = domainObj.name ; column.dataField = domainObj.name; column.width=res*.50; colsArray.push(column) ; } adg.headerWordWrap=true; adg.headerHeight=50; adg.width = res*2; adg.columns = colsArray ; adg.invalidateDisplayList(); } I got the solution for my issue. Below is the code. The only thing that I was missing was assigning datafeild and width.

private function constructDynamicColumnForADG():void{
var colsArray:Array = new Array() ;
var column:AdvancedDataGridColumn ;

for each(var domainObj: in domainObjList)
{
column = new AdvancedDataGridColumn() ;
column.headerText = domainObj.name ;
column.dataField = domainObj.name;
column.width=res*.50;

The requirment is I need to query a table and take the row data and convert it to the columns. private function constructDynamicColumnForADG():void{ var colsArray:Array = adg.columns ; var column:AdvancedDataGridColumn ; var res:Number = flash.system.Capabilities.screenResolutionX; //adg.dataProvider = fixSubsystemUserList; for each(var domainObj: in domainList) { column = new AdvancedDataGridColumn() ; column.headerText = domainObj.name ; column.width=res*.04; colsArray.push(column) ; } adg.columns = colsArray ; adg.invalidateDisplayList(); } I am able to diplay # of columns depending upon the domainList (which is populated from the database). But the issue if I am not able to difplay the column names. What do I need to do? DO I have to use Classfactory?(I not sure about the its working though) Any help is appreciated. Thanks, Deepa Hey Everyone,

I have a question about adding dynamic columns to Advanced Data Grid. The requirment is I need to query a table and take the row data and convert it to the columns.

private function constructDynamicColumnForADG():void{
var colsArray:Array = adg.columns ;
var column:AdvancedDataGridColumn ;
var res:Number = flash.system.Capabilities.screenResolutionX;
//adg.dataProvider = fixSubsystemUserList;
for each(var domainObj: in domainList)
{
column = new AdvancedDataGridColumn() ;
column.headerText = domainObj.name ;
column.width=res*.04;
colsArray.push(column) ;
}
adg.columns = colsArray ;
adg.invalidateDisplayList();

}

I am able to diplay # of columns depending upon the domainList (which is populated from the database). But the issue if I am not able to difplay the column names. What do I need to do? DO I have to use Classfactory?(I not sure about the its working though)

Any help is appreciated.

Thanks,
Deepa

Can you please file a bug report at http://bugs.adobe.com/flex/ and include a simple test case and somebody can investigate. Thanks, Peter @Sabbir Manandhar,

The problem is, the header text is not displayed at first. but when i display second table and come back to first table, the header are now visible. Again if i reload the dataProvider, the header text are not seen. can anybody explain the problem?

I found the way that you can set up the width of the column. First set up minWidth with value that you need, and then change it to be 0. I had this problem too and this is my way to make it.
