I'm trying to display a spinner on the grid while the data is GROUPING, sou the user do not think the system is frozen or with some sort of problem... The problem I'm facing is that I'm trying to use the dataBinding Event but the spinner is only shown when the data FINISHES grouping... not when it starts... while it is actually grouping, the grid appears to be frozen, which may confuse users....
Are there any solutions to this?
Thank you!
