[Solved] PreviewDataRecordCreate and ChildTableDefinitions

[Alan]

Is there any way to add a ChildTableDefinition to a TableDefinition as well as use the PreviewDataRecordCreate event to specify which rows to set IsExpandableRecord?

It seems if I do not add a ChildTableDefinition, then I can correctly set IsExpandableRecord based on a condition of a row.  But, if I add a ChildTableDefinition, the IsExpandableRecord property is just ignored, and *every* row has the expander.

My goal is to have the child expander only on certain rows and then dynamically create a ChildTableDefintion for a row that is expanded.

Hello Alan,

Since the grid will load your child data on demand you can safely add desired table definition in PreviewDataRecordCreate event.

To clarify, I don't have the child table data until the user clicks the expander (and I only want the expander for rows meeting a certain condition).

I only want to be able to view child tables for specific rows.  That's why I used PreviewDataRecordCreate to set IsExpandableRecord to false on many of the rows.  However, as soon as I add a ChildTableDefinition, the grid sets all of my rows to be expandable, even though I set most of them to not be expandable.

Hi Alan,

Can you post you code where these child definitions are added?

Our requirements have changed slightly, so I no longer need the desired behavior I'm looking for right now.  I'll post back if I still need assistance.  Thanks for your help!
