Add Child Rows when Expanding

[Chris Wescott]

Hi,
I have a GGC with a P-C relationship.
I am using two methods to fill the gird with data. 1 method gets all parents and child and the second gets all parent and only gets the children when the Parent is about to be expanded.

In the second scenario, since some Parents have no children when the user presses on the + sign I goto our webservice and get child records.

I add them to a dataset and add a relation to the Parent table (if it''s not there). This all works but when the above finishes I need to able to show that child.

I fire the above code for getting record and adding it to the dataset in the RecordExpanding event of the GGC.

I know that the records have been added correctly because when I expand all using GridGroupingControl1.Table.ExpandAllRecords() the row shows up.

Is there a refresh or something I need to call inorder to get the child to show up now that it has been added.

Regards,

Hi Chris,

I have tested this issue by creating a sample using GroupingGrid in v.4.1.0.50 and then again tested by upgrading to 4.1.0.62. I was not able to reproduce the issue.

Here is a sample

Could you please run this at your end and let me know how it goes?

Thanks for your patience.
Best Regards,

Hi,
I solved this problem in my app by doing this and I am not sure why it works. Perhaps you can shed some light on it.

Prior to adding rows I call
GridGroupingControl1.NestedTableGroupOptions.ShowAddNewRecordBeforeDetails = True

Then I add rows and when I am done adding rows I call

GridGroupingControl1.NestedTableGroupOptions.ShowAddNewRecordBeforeDetails = false

This seems to work fine. If I don''t add the above lines, it doesn''t expand. I will try to get it to reproduce in your app. but I am having no luck at this time.
