Thanks, that works perfectly.

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've implemented a custom editor along the lines described in [url=http://www.infralution.com/phpBB2/viewtopic.php?t=1073]this thread, but I want the text displayed in the cell to be read-only. That i ...

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> ...

I have a component class that I've derived from VirtualTree that I then use in a custom control. In the control, I set the VirtualTree's DataSource to a SortableBindingList<T>, and set the Typed ...

We ended upgrading to VirtualTree 4. Thanks for your help.

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 ...

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. Smile

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 ...

I have a very large List that I'm using as the data source for a VirtualTree. I'm using VirtualTree 3.14.

The problem that I'm having is that it doesn't seem to create the row cache after I add a n ...

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 ...
