How to create an effect of a banded TreeList

Question Comments

Where is TreeListHeaderMerger method defined?

HI I need to merge Columns also. Not the header. I used following code change in the below code

public class TreeListHeaderMerger
   {
       private TreeList treeList;
       private TreeListColumn columnToMerge;

       public TreeListHeaderMerger(TreeList treeList, TreeListColumn columnToMerge)
       {
           this.treeList = treeList;
           this.columnToMerge = columnToMerge;
           columnToMerge.OptionsColumn.AllowMove = false;
           GetNextColumn().OptionsColumn.AllowMove = false;
           treeList.CustomDrawColumnHeader += treeList_CustomDrawColumnHeader;
           treeList.CustomDrawNodeCell += treeList_CustomDrawNodeCell;
       }

       void treeList_CustomDrawNodeCell(object sender, CustomDrawNodeCellEventArgs e)
       {

           TreeListColumn nextColumn = GetNextColumn();
           if (nextColumn == null) return;
           if (e.Column == nextColumn) { e.Handled = true; return; }
           if (e.Column != columnToMerge) return;
           Rectangle r = e.ObjectArgs.Bounds;
           r.Width = r.Width + nextColumn.VisibleWidth;
           e.ObjectArgs.Bounds = r;
       }

       TreeListColumn GetNextColumn()
       {
           if (columnToMerge.VisibleIndex == treeList.Columns.Count - 1) return null;
           return treeList.Columns[columnToMerge.VisibleIndex + 1];
       }

       void treeList_CustomDrawColumnHeader(object sender, CustomDrawColumnHeaderEventArgs e)
       {
           TreeListColumn nextColumn = GetNextColumn();
           if (nextColumn == null) return;
           if (e.Column == nextColumn) { e.Handled = true; return; }
           if (e.Column != columnToMerge) return;
           Rectangle r = e.ObjectArgs.Bounds;
           r.Width = r.Width + nextColumn.VisibleWidth;
           e.ObjectArgs.Bounds = r;
       }
   }

But I can't able to merge columns Its hiding second column value but not the border. Once I clicking the specific field I'm able to view the data also. Am I missing any thing?
