asp.net更新的问题。
给你一个更新代码参考一下吧。如果再不行。发到我邮箱我给你改。

string id = ((TextBox)e.Item.Cells[1].Controls[0]).Text;
string title = ((TextBox)e.Item.Cells[2].Controls[0]).Text;
string type = ((TextBox)e.Item.Cells[3].Controls[0]).Text;
string price = ((TextBox)e.Item.Cells[4].Controls[0]).Text;
try
{
string cmdstr="update titles set type='"+type+"',price="+price+" where title_id='"+id+"'";
SqlCommand cmd=new SqlCommand(cmdstr,this.sqlConnection1);
this.sqlConnection1.Open();
cmd.ExecuteNonQuery();
this.sqlConnection1.Close();
this.DataGrid1.EditItemIndex=-1;
this.bind();
}
catch
{
Page.RegisterStartupScript("sb","<script>alert('错误')</script>");
}

TextBox qtyText = (TextBox)e.Item.Cells[3].Controls[0];
TextBox priceText = (TextBox)e.It
