[Closed] How do i display a prompt during a jit loading process?

Hello,

I have a data set being loaded by a datagridview in a subrollout. Naturally, when the subrollout is opened, and the datagrid is “loaded” for the first time, there can be a hang if the data is quite large.

I know how to create the prompt, but how do i know when the .net object has finished loading?

Thanks
