Show empty group expander image for rows without children rows

[Stefan Plattner]

I have a hierarchical (rows + children rows) RadGridView. I'm already using the ViewCellFormatting event in order to display my own [+] and [-] images.

Is there a way to know if a "parent" row has no children rows the event handler, so I can set an empty image in the first place? That way the user has a visual clue that the row doesn't need to be expanded.

Hello Stefan Plattner,

Thank you for your question.

Please, consider this Knowledge Base article regarding expanding/collapsing an image in hierarchical RadGridView. You can find a method in it for checking if a parent row has children.

Please, feel free to write back if you have further questions.

Kind regards,
