来晚了，你要是断点调试，将出现问题的ＳＱＬ语句放到查询分析器中，也是很容易发现错误所在的

string sqlstr = "update users set tName='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',tPass='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "', where id='"
+ GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
你应该把where 前方的那个逗号去掉 加个空格 再看看
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',tPass='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "', where id='"

＝＝＝＝＝＝＝＝＝＝＝

去除where前的逗 号
