dataGrid 多维表头、表头跨行跨列设计及绑定数据

dataGrid　其实就是一个html table 
想清楚这个以后，要设置多维表头就好办了 
html代码 

复制代码代码如下:

<asp:DataGrid ID="DataGrid1" runat="server" 
onitemdatabound="DataGrid1_ItemDataBound"> 
</asp:DataGrid> 

然后绑定数据 

复制代码代码如下:

protected void Page_Load(object sender, EventArgs e) 
{ 
string strsql = "select EmpID, Name, BranchID, LoginID, Pwd, Sex, EmpCode, Email, OfficeTel from mrBaseInf"; 
SqlConnection con = new SqlConnection("server=.;database=iOffice2009;uid=sa;pwd=sa"); 
DataSet ds = new DataSet(); 
SqlDataAdapter ter = new SqlDataAdapter(strsql, con); 
con.Open(); 
ter.Fill(ds); 
con.Close(); 
this.DataGrid1.DataSource = ds; 
DataGrid1.DataBind(); 
} 

接下来添加DataGrid1_ItemDataBoun事件 

复制代码代码如下:

protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e) 
{ 
if (e.Item.ItemType==ListItemType.Header) 
{ 
e.Item.Cells[0].RowSpan = 2; 
e.Item.Cells[1].RowSpan = 2; 
e.Item.Cells[2].RowSpan = 2; 
e.Item.Cells[3].RowSpan = 2; 
e.Item.Cells[4].RowSpan = 2; 
e.Item.Cells[5].ColumnSpan = 4; 
e.Item.Cells[5].HorizontalAlign = HorizontalAlign.Center; 
e.Item.Cells[5].Text = "测试</td></tr><tr><td>列1</td><td>列2</td><td>列3</td><td>列4</td></tr>"; 
e.Item.Cells[6].Visible = false; 
e.Item.Cells[7].Visible = false; 
e.Item.Cells[8].Visible = false; 
} 
}
