如何在ItemDataBound内获得DataGrid的列名称HeaderText
作者：活靶子 来源：
http://www.cnblogs.com/huobazi/archive/2004/11/03/60081.aspx如果 AutoGenerateColumns="false" 使用绑定列，模板列则比较好办，直接使用 YourDataGrid.Columns[编号].HeaderText 获得可是,如果 AutoGenerateColumns="true" ,就比较麻烦了但是可以变通做到。
示例：
<%@ Page Language="C#" Debug="true" %>
<%@ Import Namespace="System.Data" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "

<html xmlns="

<head>
<title> ItemDataBoundGetColumnName </title>
<script language="c#" runat="server">
void BindGrid()
{
DataTable dt = new DataTable();
DataRow dr;
dt.Columns.Add(new DataColumn("IntegerValue", typeof(Int32)));
dt.Columns.Add(new DataColumn("StringValue", typeof(string)));
dt.Columns.Add(new DataColumn("DateTimeValue", typeof(DateTime)));
dt.Columns.Add(new DataColumn("BoolValue", typeof(bool)));
dt.Columns.Add(new DataColumn("CurrencyValue", typeof(double)));
for (int i = 0; i < 36; i ) {
dr = dt.NewRow();
dr[0] = i;
dr[1] = "项 " i.ToString();
dr[2] = DateTime.Now;
dr[3] = (i % 2 != 0) ? true : false;
dr[4] = 1.23 * (i 1);
dt.Rows.Add(dr);
}
dg.DataSource= dt;
dg.DataBind();
}
void Page_Load(object o, EventArgs e)
{
dg.PagerStyle.Mode = PagerMode.NumericPages;
if(!IsPostBack)
{
BindGrid();
}
}
void btnClick(object o , EventArgs e)
{
Response.Write("页面回发,但是不执行ItemDataBound");
}
void PageChange(object o , DataGridPageChangedEventArgs e)
{
dg.CurrentPageIndex = e.NewPageIndex;
BindGrid();
}
void ItemDataBound(object o , DataGridItemEventArgs e)
{
if(e.Item.ItemIndex > -1 )//必须
{
DataRowView drv = (DataRowView)e.Item.DataItem;
for (int i=0; i<drv.Row.Table.Columns.Count ; i )
{
Response.Write(drv.Row.Table.Columns.ColumnName " ");
}
}
}
</script>
</head>
<body>
<form runat="server">
<ASP: DataGrid id="dg" runat="server"
HeaderStyle-BackColor="#aaaadd"
AutoGenerateColumns="true"
AllowPaging="true"
PageSize="6"

</asp: DataGrid>
</br>
<asp: button id="btn" runat="server" Text="我是按钮,按我一下"></asp:button>
<p>在AutoGenerateColumns="false"使用绑定列或者模板列的时候只需要使用 </P>
<p><font color="blut">YourDataGrid.Columns[编号].HeaderText</font> 去获取
</P>
