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));
        }

Hi:
EasyReport is a Report of asp.net, it is very simple and powerful.
It contains three parts:report designer \report serve programme and the API
support Winform and Asp.net.EasyReport is suitable for two kinds of user:the final user and the software provider. It can be used as an independent programme and a part of one programme as well.The report format can be saved in the database ,and you can easily make a repor just move the target word with the mouse .EasyReport supports different databases such as
SqlServer, Oracle,Access and so on.

I'll be glad to talk about the details of my EasyReport with you later.
Smile | :)
