asp.net gridview动态添加列，并获取其数据；
1，绑定数据前先动态添加列，见方法CreateGridColumn（只在第一次加载动态添加）；
2，gvlist_RowDataBound为对应列添加控件；

{
BoundField bfield = (BoundField)oCol;
if (bfield.DataField.ToUpper() == colName.ToUpper())
{
return ndx;
}
}
ndx++;
}
return ndx;
} }
}
BasePage：
using System;
using System.Collections.Generic; using System.Web; namespace web.code
{
public class BasePage : System.Web.UI.Page
{
protected override void OnInit(EventArgs e)
{
if (!UserOnline.Current.IsLogin)
{
Response.Redirect("/login.aspx", true);
}
//base.OnInit(e);
} protected int PageNum = ; protected void Alert(string str)
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "success", "alert('" + str + "');", true);
} }
}
注意：动态添加列通过如下获取
//"gvlist$ctl" + (i + 2).ToString().PadLeft(2, '0') + "$controlid"
//Request.Form["gridviewID$ctl行号$控件ID"]
