C# 在Asp.net C中以另一页的形式更新datagrid数据
我是asp.net新手,现在我正在测试简单的方法。我想以另一个页面的形式编辑datagrid。这是我的密码C# 在Asp.net C中以另一页的形式更新datagrid数据,c#,asp.net,C#,Asp.net,我是asp.net新手,现在我正在测试简单的方法。我想以另一个页面的形式编辑datagrid。这是我的密码 using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.

}
这是我的更新功能
public bool Update_memberType(int id, string name, int dsc)
{
string connectionString =
WebConfigurationManager.ConnectionStrings["Spa"].ConnectionString;
SqlConnection myConnection = new SqlConnection(connectionString);
int memid = id;
string membtype = name;
int dsrate = dsc;
Boolean chk = false;
try
{
myConnection.Open();
SqlCommand cmd = new SqlCommand("Update_Membtype", myConnection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@mem_typeId", memid);
cmd.Parameters.AddWithValue("@membertype_name", membtype);
cmd.Parameters.AddWithValue("@dsc_rate", dsrate);
cmd.ExecuteNonQuery();
chk = true;
}
catch (Exception err)
{
chk = false;
}
return chk;
}
当我尝试更新数据时,它不会改变任何东西。变量有其原始值。不会更改为文本框中的新数据。如何修复这些错误。请 你有什么错误吗?另外,您应该在finally块中关闭连接。我收到更新成功消息,但数据未更新。当我调试代码变量时,会使用旧值进行赋值。我认为这是个问题。
