How to customize Hierarchy Expander Column Header

[Keith]

Hi,

I need to add a ToggleButton to the Hierarchy Expander column header that automatically appears when using a ChildTableDefinition.  Any suggestions would be greatly appreciated.

Thanks,
Keith

Hello Keith,

If you want to maintain the expanding functionality of the row layout I recommend you to edit the default template of GridViewRow. Looking at it you will find the HierarchyChildPresenter which is responsible for displaying child tables and the toggle button which is used to expand and collapse a row.

All the best,
