Grid data grouping "visual feedback" to user

[Daniel]

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!

Hello Daniel,

A more appropriate way to do such functionality will be by handling the DataSource requestStart and requestEnd(or maybe the change) event. Those are events that wraps the data retrieving and processing. The Grid's dataBinding and dataBound event marks the start and end of Grid widget data rendering which happens after the data is processed.
