TreeGrid ready property

[roblajollaParticipant]

Hi,

When is the ready function invoked? I am hoping it is invoked each time the data is loaded but that doesn’t seem to be the case. The tree grid only seems to run the ready function the first time data is loaded. I am trying to modify the data source for the grid via a new data adapter. The tree grid is properly displaying the data but the ready function is not invoked. Please see example below (modification of your base tree grid example).

Thanks,

Rob

Hi roblajolla,

The ready callback function is called 1 time only, after the widget is created. That function is not called when you reload data.

Best Regards,
