how to use flex datagrid lockedcolumncount for two columns?

How do you use flex datagrid lockedColumnCount for two columns?

For example, I have 5 columns of datagrid columns: A, B, C, D and E. I want the A and E columns to be locked and the remaining columns able to be scro开发者_Python百科lled horizontally.

How can I do that?

To use lockedColumnCount, do something like this:

<mx:DataGrid id="myDataGrid" lockedColumnCount="2" >

The DataGrid always locks the leftmost columns. There is no way to lock the leftmost column and the rightmost column. (As far as I know this isn't even possible in Excel). You'll have to extend the DataGrid to do this; although logistically I'm not relly seeing how it'd work.

I believe you could put two datagrids side by side.

So basically you have one hbox, with two datagrids in it.

The first with columns A thru D and the second with just E.

Set lockedColumnCount=1 on both and set the horizontalScrollPolicy=false on the second.

I havnt tried this and could be completely wrong, but hope this helps someone.
