GridGrouping not always displaying child records in a hierarchical data source

[Brian R]

Hey there,

I have a project where I have a GridGroupingControl on a form. I load this grid with a dataset consisting of two tables which are to be displayed in a hierarchical fashion, departments with details below them.

The code that loads the dataset and then in turn sets it to the grid's data source is executed in a thread via the use of a MethodInvoker. I then check the control if it needs to be invoked and do a grid.Invoke() in order to populate it with the data.

The problem I am experiencing is that even though the data is always coming back solid, typically one out of every ten times I run this code the grid does not display the details below the departments. No error is thrown. I’ve checked the data when this happens and I see valid data there. I can try to view the same records several times in a row and it appears to fail randomly.

I am at a complete loss as to what is happening here. I’m using 4.202.0.60 of the grid control. Any suggestions as to what might be happening here?



Thanks in advance,

Brian
