你前面用的是控件这样是获取不到的，要这样
((LinkButton)e.Item.FindControl("LinkButton1")).Text你试一试！

Answer 3

你前面用的是控件这样是获取不到的，要这样
((LinkButton)e.Item.FindControl("LinkButton1")).Text你试一试！
rowdatabound 
里面没有 e.item.Item.FindControl() 方法

Answer 4

我刚发现 e.Row.Cells[1].Text;获取的是HeaderText的值，而并不是绑定的数据的值

Answer 5

rowdatabound 
里面没有 e.item.Item.FindControl() 方法
你太逗了！是e.item.FindControl()不是 e.item.Item.FindControl()string str = e.Row.Cells[0].Text;你不是想获取编号吗？

Answer 6

我刚发现 e.Row.Cells[1].Text;获取的是HeaderText的值，而并不是绑定的数据的值switch (e.Item.ItemType)
        {
            case ListItemType.AlternatingItem:
            case ListItemType.Item:
把你的代码写在这里面
 break;
}

Answer 7

  protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowIndex != -1)
            { if (e.Row.Cells[2].Text.Replace("&nbsp;", "").Equals("1"))
                {
                    e.Row.Cells[1].Style.Value = "color:#ff0000";
                    e.Row.Cells[2].Style.Value = "color:#ff0000";
                    e.Row.Cells[3].Style.Value = "color:#ff0000";
                    e.Row.Cells[4].Style.Value = "color:#ff0000";
                    e.Row.Cells[5].Style.Value = "color:#ff0000";
                    e.Row.Cells[6].Style.Value = "color:#ff0000";                   // e.Row.ForeColor = Color.Red;
                }
}

Answer 8

rowdatabound 
里面没有e.item.FindControl()

Answer 13

我的想法是，从数据库里查出来的那几条数据(指定的某个字段)，如果和gridview里的某条数据(指定的某个字段)相同，则让这行背景为其他颜色。给位给我的都是设置死数据的背景。
现在我gridview里的第一个字段用的是LinkButton绑定的，
用了insus的方法  LinkButton link = e.row.Findcontrol("LinkButton1")  as LinkButton； link为null。获取不到数据
 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            DataTable dt = pm.Get30DaysInfo();
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                LinkButton link = e.Row.FindControl("LinkButton1") as LinkButton;
                string str = link.Text;
                string str1 = dt.Rows[i][1].ToString();
                if (str == str1)
                {
                    e.Row.BackColor = System.Drawing.Color.Yellow;
                }  
            }
        }

Answer 14

你的头模板肯定是没有LinkButton1
加个判断
  if (e.Row.RowIndex != -1)

Answer 15

e.Row.RowIndex  = -1； 头模板里的确是有LinkButton1的，我的代码都贴到上面了，你应该是可以看到的。

Answer 16

  if (e.Row.RowIndex != -1) 为什么会是false呢，难道是因为我手动绑定的gridview吗？

Answer 17

e.Row.RowIndex  = -1； 头模板里的确是有LinkButton1的，我的代码都贴到上面了，你应该是可以看到的。

<HeaderTemplate></HeaderTemplate>这是头模板
  switch (e.Row.RowType)
            {
                case DataControlRowType.DataRow:
  DataTable dt = pm.Get30DaysInfo();
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                LinkButton link = e.Row.FindControl("LinkButton1") as LinkButton;
                string str = link.Text;
                string str1 = dt.Rows[i][1].ToString();
                if (str == str1)
                {
                    e.Row.BackColor = System.Drawing.Color.Yellow;
                }  
            }
                    break;
}
