Hi, I'm using Flex 3.2 and I have a DataGrid which implements a column of checkboxes to select rows. I started with Alex' example. Then I added a header renderer on the checkbox column such that if check the header, then all rows are selected. To implement the select all behavior, I'm creating an array of indices for [0..n] and assigning that array to mx:DataGrid.selectedIndices.
For the most part this works fine. But if the DataGrid is editable, then I sometimes have a problem. The problem is that if all rows are selected, and you click on an editable cell, sometimes the cell becomes editable without deselecting all of the other rows. The behavior I want is that if you start editing a cell, then just that row becomes selected. This happens some of time, but not all of the time. If the grid is non-editable, then I can't reproduce the problem. I overrode mx:DataGrid.selectItem() in order to clear the checkbox in the header renderer any time a single item is selected. I've noticed that when the problem behavior occurs, the mx:DataGrid.selectItem() method is never called. It's almost like there's some race condition between selecting an item and starting a cell edit. Any ideas on how I could work around this? Thanks, Glenn
