FLEX 2 Programmatically adding DAtagrid column to a datagrid

hi im using the following code to try to add a datagrid column to a datagrid
     var dg:DataGrid = new DataGrid();
     dg.width=ca_prop_detail.width;
     dg.height=ca_prop_detail.height;

     var dc1:DataGridColumn = new DataGridColumn("DateRange");
     dg.addChildAt(dc1,0);

but i keep getting an error saying

1067: Implicit coercion of a value of type mx.controls.dataGridClasses:DataGridColumn to an unrelated type flash.display

please help this is very urgent

Hi Robinsonx6.

addChildAt() in Flex 2 is used mainly to add components to a display. The error is basically telling you that a DataGridColumn is not a valid component to do this with.

Instead of addChildAt(), try addColumn():

dc1 = new DataGridColumn("DateRange");
dg.addColumn(dc1);

Let me know how it turns out.

a DataGrid doesnt appear to have a addColumn, any ideas please

Hmm, well despite the fact that it isn't in the Flex documentation, I've seen a couple sites use it. Here's one by Alessandro "Sephiroth" Crugnola:

http://www.sephiroth.it/index.php?blogId=2005_12_06_weekly.html

He does a lot of work with Adobe, in fact he wrote several of the classes for Flash MX (and probably more).
Anyways, check it out. He creates a couple DataGridColumns and uses adColumn() to attach them to a DataGrid.

Cheerio

im not sure what is happening ,ive seen this link before, ive even created a tiny class to extend the DataGrid in Flex2 and i get no addColumn function,

Weird. Does it give you an error when you compile it, or does it simply not do anything when you try to run it?

Thanks. Sorry I couldn't be of more help, but I'll keep looking.

I'm going to need this functionality too, and if I find a solution, I'll post it to this question.
