Here's is what i came up with:
YOu can run one query to get the list of all columns from a table using the following SQL code:
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Customers'
Once you do that you can run the query for your table with the selected columns with the following applet property code:
function MyFunc(){
               document.MyApplet.getGridObject().setDisplayColumns('CompanyName,City');
               document.MyApplet.updateGrid(true);
User the following to extract all selected rows:
selRows = parseInt(myGrid.getSelectedRowCount());
You then itterate through the iGrid to extract the value:
for (var i=1; i<=selRows; i++) {
     selRowNum = myGrid.getSelectedRowAt(i);
     selDate = myGrid.getCellValue(selRowNum,1);
