Introduction

 It is a cool asp.net DataGrid Merger, it is very simple and useful.

 Only use a few code, you can merge datagrid's Header and body.

 I hope it is helpful  to you!    

Using the code  

 protected void Page_Load(object sender, EventArgs e) 
 { 
  DataTable dt = new DataTable(); 
  AddTableColumn(dt, "f1", null); 
  AddTableColumn(dt, "f2", "income|f2"); 
  AddTableColumn(dt, "f3", "income|f3"); 
  AddTableColumn(dt, "f4", "income|Last Year|f4");
  AddTableColumn(dt, "f5", "income|Last Year|f5"); 
  AddTableColumn(dt, "f6", null); 
  AddTableColumn(dt, "f7", "outcome|f7");
  AddTableColumn(dt, "f8", "outcome|f9");
  for (int r = 1; r <= 6; r++) 
  {
    DataRow dr = dt.NewRow(); 
    dr["f1"] = "" + (r / 4); 
    dr["f2"] = "" + (r / 2);
    for (int col = 3; col <= dt.Columns.Count; col++) 
      dr["f" + col] = "" + (col*r); 
      dt.Rows.Add(dr); 
  }   
  DataGrid1.DataSource = dt; 
  foreach (DataColumn dataColumn in dt.Columns)
  {
     BoundColumn column = new BoundColumn();
     column.DataField = dataColumn.ColumnName; 
     column.HeaderText = dataColumn.Caption == null ? dataColumn.ColumnName : dataColumn.Caption; 
     DataGrid1.Columns.Add(column); 
  } 
  
  DfawWeb.CtrlUtil.DataGridMerger merger = new DfawWeb.CtrlUtil.DataGridMerger(DataGrid1);
    merger.AddMergeColumn("f2"); //  
    merger.AddMergeColumn("f1"); //   
  DataBind(); 
}
public interface IMatrix 
{ 
  int RowCount { get; } 
  int ColumnCount { get; } 
  object GetCellValue(int row, int col);
}

 public class MergeCell
 { 
   public System.Drawing.Rectangle Bounds; 
   public object Value; // &#20540; 
 } 

 public class MergeCellList : CollectionBase 
 { 
  public enum MergeModeEnum 
  {
    RowCol = 0,
    Col,
    Row 
  }
  ...
}
void dataGrid_ItemCreated(object sender, DataGridItemEventArgs e)
        {
            if (ListItemType.Item == e.Item.ItemType || ListItemType.AlternatingItem == e.Item.ItemType)
            {
                if (canMergColHash != null && canMergColHash.Count > 0)  //&#21512;&#24182;&#34920;&#20307;
                    e.Item.SetRenderMethodDelegate(new RenderMethod(BodyMergeRenderMethod));
                return;
            }
            if (cellList != null && ListItemType.Header == e.Item.ItemType)  // &#21512;&#24182;&#34920;&#22836;
                e.Item.SetRenderMethodDelegate(new RenderMethod(HeaderMergeRenderMethod));
        }
