Please accept my apology for the delay.
The Kendo UI Grid should have a built-in kendo progress. However, as requested - below are two different ways to initialize your own Kendo UI progress indicator.
1) Attach an event handler to the requestStart
event of the Kendo UI Data Source.
2) Choose either Kendo UI progress()
method or a Progress Bar
and begin displaying the relevant loading indication.
3) Add a handler function to the requestEnd
event of the Kendo UI Data Source or the Kendo UI Grid dataBound
4) End the loading indication
Let me know if you need further help.
