Hi everybody, I create on fly nodes on a UltraTree and I need to customize the columns depending on the type of node. If the node is a child node I do not want to show again the header, for example.

I am using this code but it doesn't work as it should because the column size stays small and doesn't resize as it should, but the header is now not visible as I need:

// this method has a boolean value called header which tells me if I want to display or not the header for a specific column set. The autosize doesn't work.

            var columnsSet = new UltraTreeColumnSet();
            columnsSet.LabelPosition = header ? NodeLayoutLabelPosition.Default : NodeLayoutLabelPosition.None;
            var colName = new UltraTreeNodeColumn { Key = "Name" };
            colName.AutoSizeMode = ColumnAutoSizeMode.AllNodesWithDescendants;
            columnsSet.Columns.Add(colName);
            var colStatus = new UltraTreeNodeColumn { Key = "Status" };
            colStatus.AutoSizeMode = ColumnAutoSizeMode.AllNodesWithDescendants;
            columnsSet.Columns.Add(colStatus);
            var colMessage = new UltraTreeNodeColumn { Key = "Message" };
            colMessage.AutoSizeMode = ColumnAutoSizeMode.AllNodesWithDescendants;
            columnsSet.Columns.Add(colMessage);
            return columnsSet;
