I am new to flex and have been impressed with the components
and been converted from Open Laszlo.
However I have a data provider that returns xml and I have no
idea what the columns are going to be. So potentially I could need
a checkbox and not know the column name, so I cant create the
mapping with the datagridcolumn because I dont know the name, I
know the type of field from the JSP.
Also if i did use datagridcolumn to map to a field name, it
doesnt display the other columns because I havent added them in to
the column tag. Is there any way to get the other columns to
display without adding them to the datagridcolumns mapping as I
dont know what these are going to be at runtime because they are
It sounds like you just want to know how to add columns
dynamically. As you loop through your XML data set you can add
columns to the DataGrid:
var columnArray:Array = new Array();
var dc:DataGridColumn = new DataGridColumn();
dc.headerText = "something from your xml data";
dc.dataField = "something from your xml data";
// any other properties to set
columnArray.push( dc );
.. continue you loop ...
Now assign the Array of DataGridColumns to the DataGrid.
grid.columns = columnArray;
