gridview更新错误 指定的参数已超出有效值的范围。参数名：index

[seles]

更新错误，不知道为什么，下面是详细信息：
用户代码未处理 System.ArgumentOutOfRangeException
Message="指定的参数已超出有效值的范围。\r\n参数名: index"

更新代码如下：
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string Name = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim();
string Zhuti = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim();
string Qq = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim();
string Email= ((TextBox)(GridView1.Rows[e.RowIndex].Cells[4].Controls[0])).Text.ToString().Trim();
string Content = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[5].Controls[0])).Text.ToString().Trim();
string Time=((TextBox )(GridView1.Rows [e.RowIndex ].Cells[6].Controls [0])).Text .ToString ().Trim();
SqlConnection sqlcon=new SqlConnection ();
sqlcon .ConnectionString ="server=(local);uid=sa;pwd=sa;database=post";
sqlcon .Open ();
string sqlstr = "update post set name='" +Name + "',zhuti='"+ Zhuti + "',qq='"+Qq + "' ,email='"+Email +"',content='"+Content +"',time='" +Time +"' where id='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";

SqlCommand sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcom.ExecuteNonQuery();
GridView1.EditIndex = -1;
sqlcon.Close();
DataBind();


}
请各位大侠给我看看，我都快疯了。

这个看代码看不出什么问题的。建议在string name 处加断点，看看e.RowIndex的值。

[cooolchen]

name='" +Name + "',zhuti='"+ Zhuti + "',qq='"+Qq + "' ,email='"+Email +"',content='"+Content +"',time='" +Time +"'

跟踪这些变量是否能取到值，要么是e.rowindex,要么是cell里面的索引超出范围。

[seles]

DataKeyNames="id"已设，看问题就出在string Name = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim(); 这一句

[amandag]

GridView是否设置了DataKeyNames属性为表的主键

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="id" >

[longyong712]

单元格的索引有错

那应该怎么改一下呢？？？
