Yet another vexing WHDG issue.  I am working with 13.2 build 3028.

I have a page with two instances of WHDG; one is single-level, one has a child band.  Markup is below.  I've made the configuration of the two grids as similar as possible.

In both grids, I have a number of non-editable columns and one editable checkbox template column (on the parent in the parent/child grid).

I want to do manual CRUD, so I am handling the RowUpdating event for each one.

The single-tier grid works fine, firing RowUpdating for each modified row on every postback.  The parent/child grid, however, fires RowUpdate only on every second postback.  For wxample, I click a row to change the checked value (the data in the row switches to italics, so I know the grid sees the edit), then I click a button that does a post back, but RowUpdating doesn't fire.  Also, the row in the grid returns to it's original values.  If I click the checkbox again and cause a postback, the RowUpdating DOES fire.  Another edit and postback does NOT fire the event, then a fourth edit and postback DOES fire it, etc.

I know that the postback always rebinds the data to the grid, but it does exactly the same thing every time, so that shouldn't affect the RowUpdating.

I've done a lot of exploration on this and can't find what is happening.

Any suggestions on what could be causing this?
