I'm still not sure what you want. If you click into a place on the ListBaseContentHolder where there are no renderers because you don't have enough data in your DP, then yeah, it'll return null. If you want to estimate what index it would be, you can use rowHeight and rowInfo to guess at it.
If a header gets clicked on, you can look at event.target, figure out if it is a renderer or child of a renderer, make sure it is a header renderer and look at the dataGridColumn in its .data property. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Cato Paus Sent: Tuesday, April 22, 2008 11:20 AM To: [email protected] Subject: [flexcoders] Re: Overriding the mouseClickHandler in DataGrid Hi Alex thanks for reply, the r = mouseEventToItemRenderer(event); is returning null if I hit the header (DataGridHeader), and the ListBaseContentHolder. Can I get a index from somewhere, I have try to get the index and it seams like it have a delay, I'm getting the pri value, I have to click it two times before the index changes. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > You want to know if the header got clicked?
