>How do you differentiate between a row or column change in a grid. RowColumnChange is just sent a number so it could be either one. I'm trying to stop a row change when the user has modified a record. Thanks.

in beforerowcolchange event store activerow to a property.
in afterrowcolchange event check to see if modifications have occurred and if activerow is not equal to the value stored in the property if so give error message and set active row back to the value in the property.
