You can create datagrid column dynamically by using the following method,
//Specify the column name & description
var columnName:String = "Sample";
var columnDescription:String = "Sample";
var cols:Array;
var dgc:DataGridColumn = new DataGridColumn(columnName);
dgc.dataField = columnName;
dgc.headerText = columnDescription;
dgc.sortable = true;
dgc.width = 50;
cols = dataGrid.columns; // this line is needed if u have
already column for the grid
cols.push(dgc);
dataGrid.columns = cols;
Note:
If you want to create multiple column then copy the above code inside of
function and pass column name and description as variable. And don't forget
to assign the existing column *( cols = dataGrid.columns;)*, otherwise
last column which u added lastly will be shown.
Then set the dataprovider for the grid,
var collectionData :ArrayCollection;
collectionData = new ArrayCollection({sample: "Test"});
dataGrid.dataProvider = collectionData;
Try it out....
