Just like in the mxml the DataGrid has a columns property that
contains an array of DataGridColumn objects. In your case you just
need to populate an array with one MyExtendedDataGridColumn instance
for each column and then set it to the columns property of the DataGrid:
var numOfColumns:int = 3;
var cols:Array = new Array(numOfColumns);
for (var i:int = 0; i < numOfColumns; i++)
{
var dc:MyExtendedDataGridColumn = new MyExtendedDataGridColumn();
...set various properties of column (headerText, width, sortable,
etc)...
cols.push(dc);
}
myDataGrid.columns = cols;
