  Hey all! I was following the example listed here: https://www.grapecity.com/en/blogs/creating-outlines-and-trees-with-the-c1flexgrid-control

  And I got the Nodes and Tree working just fine.

  However, it is not very clear how to handle sorting after the grouping is applied. I tried to find the analyze example but couldn’t find it. We are already handling all sorting programatically, so any direction on how to sort and keep the grouping in place would be great, thanks!

  Hi!

  To achieve the desired behaviour, please use AfterSort event in which you can apply grouping once the data is sorted. I am attaching a sample application for your reference.

  Sweet that helped a lot! Thank you! One last question(hopefully)!

  How do I essentially “clear” a groupby? I do grid.tree.clear, but that doesn’t delete the node rows, and I’m not seeing a way to actually delete a node row… I can set it to be invisible, but if they are able to dynamically group and ungroup, I would have a lot of node rows taking up space…
