Re: [flexcoders] Re: DataGrid HeaderRenderer and DataProvider

Sun, 15 Oct 2006 21:43:24 -0700

Creating varying number of datagrid columns is fairly straightforward. Datagrid will by itself draw the columns if you do  not specify the <mx:DataGridColumn .../> in your code. The columns will be created according to the properties that each dataProvider object contains. For displaying an icon on the header, you will have to extend the datagrid control and do some tweaks.

Thanks

No problem jelentz, check out the link I've provided below. While you
are looking to dynamically set the dataProvider of a DataGrid the
content
of the article discusses a ComboBox. The takeaway from the article is
how to create your own custom DataGrid class (by extending DataGrid)
and then writing the appropriate code to manipulate the dataProvider.
The article does a good job explain this.

Let me know if you have questions (note, I didn't write the article.)
