Thanks, that did the trick.
A follow-up question: is there a way to specify a secondary sort column when using the automatic sorting provided by this mechanism? In other words, if I'm sorting on co ... |

I don't actually have a derived list class. I was just trying to use a SortableBindingList<MyObj> as the DataSource.
Do I need to create a new class that has a SortableBindingList<MyObj> ... |

It looks like that property was added in 4.0, and we're stuck with 3.15.2 for the time being. Is there a way to do the same thing in this older version? |

I have a VirtualTree control that uses data binding in the Designer. One of the columns is bound to a property with return type of an enum. I've decorated the enum with a TypeConverter that uses a sim ... |

The standard behavior in a Windows Forms tree control is to remember which sub-nodes were expanded when a node is collapsed and then re-expanded. The default behavior in VirtualTree (I'm using 3.15) a ... |

I've simplified the programmatic data binding to be more efficient. There were two columns with CheckBox editors where OnGetCellData wasn't using the DataSource, and that's now fixed. So yes, DataSour ... |

LastRowIndex is equal to the number of rows that should be loaded into the control at the time GetRows is called. I made sure of that before posting my follow-up question.
Unfortunately, the dat ... |

The good news is that calling GetRows(), even on the main thread, doesn't add appreciably to the dialog's load time. The bad news is that it doesn't seem to help - scrolling through the tree the first ... |

Setting the style for the cells instead of the row does the trick. The row style seems to be irrelevant, as it works with or without setting the row style as long as I set the style in OnGetCellData. ... |

Adding a call to row.Tree.UpdateRowData(row) at the end of the SetValueForCell doesn't seem to help. SetValueForCell is getting called before OnGetRowData, so I can see that the underlying data have b ... |
