No child grid script descriptors are available????
posted

Hello,

i want to Bind EntityCollections (LLBL-Engine) to the WebHierarchicalDataGrid.

When I start the ASP.NET site. The Job will be shown. When i click on the Job, to watch its protocolls, this error is being displayed:

Runtime Exception: No child grid script descriptors are available!

Job entity got an EntityCollcetion<AppJobProtokollEntity>. That has to be the childband. Both got a JobId.

Can someone help me?

Kind regards,

David Müller

AppJobEntity job = _jobManager.GetJob(ticket, Guid.Parse("E57E0B1A-9C31-4987-8800-D5E8EC4B609F"), true);

 

 

 

List<AppJobEntity> list = new List<AppJobEntity>();
list.Add(job);

listProtokoll = job.AppJobProtokolls.ToList<
