>When I delete a record in a grid, it triggers BeforeRowColChange three times, and in some cases, even more times. When and how this event will be triggered in addition to the normal moves among the records? Does the index play a role in this situation? How can I control the number of times that this event will be triggered?
Wei Lin,

You cannot control how often any event will be triggered, thats what evetns are, they fire when something happens. The control is found in controlling what happens.

As for how many times BeforeRwoCol will fire on a delete action, it depends on what your delete code is doing and how often the grid will change its row or column.
