Hi,
now I discovered another Problem depending on my last Thread: https://www.telerik.com/forums/avoid-multiple-calls-of-async-updatehandler-when-pressing-enter
Your solution works fine as long as I do not enter the very first value in my grid and it makes no difference which row is changed.
When I enter the first value then the UpdateHandler does not get triggered. Only my ChangeHandler.
Do you have an idea why this is happening?
