[zm_2012]

//更新事件
protected void xgvRealtionList_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = (GridViewRow)xgvRealtionList.Rows[e.RowIndex];
TextBox txteeName = row.FindControl("txteeName") as TextBox;
TextBox txterName = row.FindControl("txterName") as TextBox;
TextBox txtdeName = row.FindControl("txtdeName") as TextBox;
TextBox txtewName = row.FindControl("txtewName") as TextBox;
//获取到要更新的内容后如何进行更新，我的数据源是DataTable， DataTable中的数据是从Execl表格中获取
//也就是说我的数据更新要在DataTable中执行，请帮小弟写出源码

}

DataRow[] arrDr = dt.Select("条件"); -- 最好是主键，查出DataTable中唯一一条数据
DataRow dr = arrDr[0];
dr.BeginEdit();
GridViewRow row = (GridViewRow)xgvRealtionList.Rows[e.RowIndex];
TextBox txteeName = row.FindControl("txteeName") as TextBox;
TextBox txterName = row.FindControl("txterName") as TextBox;
TextBox txtdeName = row.FindControl("txtdeName") as TextBox;
TextBox txtewName = row.FindControl("txtewName") as TextBox;
dr["字段名"] = txteeName.Text;
....给dr要修改的字段赋值
dr.EndEdit();
dt.AcceptChange();

DataTable dt = xsldata(2);
//筛选表达式“50214827”(txtID.Text)的计算结果不是布尔值项。 求解！！！！！
DataRow[] arrDr = dt.Select(txtID.Text);
