Loading message for wide data sets

I have a wide dataset that currently take 12 seconds to load before the grid is visible. Smart rendering doesnt help as the dataset is wide not tall. How can I show a message to explain that the data is loading/grid rendering?

many thanks

You can use “onXLE” and “onXLS” events. Please check example here dhtmlx.com/docs/products/dht … ation.html

perfect - thank you
