编写数据库存储过程修改信息代码如下：
编写服务端后台代码如下：
//修改奖品信息
[OperationContract]
public int UpdatePrize(string strPrize_number, string strPrize_name, string strIntegral,
bool bolWhether_activity, string strRemarks,int intPrize_ID)
{
SqlParameter[] mysqlparameter = {
new SqlParameter("@type",SqlDbType.NChar),
new SqlParameter("@Prize_number",SqlDbType.NChar),
new SqlParameter("@Prize_name",SqlDbType.NChar),
new SqlParameter("@Integral",SqlDbType.NChar),
new SqlParameter("@Whether_activity",SqlDbType.Bit),
new SqlParameter("@Remarks",SqlDbType.NChar),
new SqlParameter("@Prize_ID",SqlDbType.Int)
};
mysqlparameter[0].Value = "UpdatePrize";
mysqlparameter[1].Value = strPrize_number;
mysqlparameter[2].Value = strPrize_name;
mysqlparameter[3].Value = strIntegral;
mysqlparameter[4].Value = bolWhether_activity;
mysqlparameter[5].Value = strRemarks;
mysqlparameter[6].Value = intPrize_ID;
int count = myDALMethod.UpdateData("Frm_Login", mysqlparameter);
return count;
}
编写客户端后台代码如下：
//全局变量
DataRowView DGVR;//接收一行数据
BLL.Login.LoginClient myClient = new BLL.Login.LoginClient();
public WD_UpdateAllot(DataRowView drv)
{
InitializeComponent();
DGVR = drv;
}
private void WindowName_Loaded(object sender, RoutedEventArgs e)
{
////页面数据回填
txt_number.Text =(DGVR.Row["Prize_number"]).ToString();
txt_name.Text = (DGVR.Row["Prize_name"]).ToString();
txt_Integral.Text =(DGVR.Row["Integral"]).ToString();
if (DGVR.Row["Whether_activity"].ToString() == "是")
{
chk_activity.IsChecked = true;
}
else
{
chk_activity.IsChecked = false;
}
txt_remarks.Text =(DGVR.Row["Remarks"]).ToString();
}
//确认修改按钮
private void btn_Affirm_Click(object sender, RoutedEventArgs e)
{
try
{
string strPrize_number = txt_number.Text.Trim();
string strPrize_name = txt_name.Text.Trim();
string strIntegral = txt_Integral.Text.Trim();
bool bolWhether_activity = (bool)chk_activity.IsChecked;
string strRemarks = txt_remarks.Text.Trim();
int intPrize_ID = Convert.ToInt32(DGVR.Row["Prize_ID"]);
//执行服务方法
int count = myClient.UpdatePrize(strPrize_number, strPrize_name, strIntegral, bolWhether_activity, strRemarks, intPrize_ID);
if (count > 0 )
{
MessageBoxResult dr = MessageBox.Show("账号修改成功！", "系统提示", MessageBoxButton.OKCancel,
MessageBoxImage.Asterisk); //弹出确定对话框
if (dr==MessageBoxResult.OK)
{
Close();
}
}
else
{
MessageBoxResult dr = MessageBox.Show("账号修改失败，请重新操作！", "系统提示", MessageBoxButton.OKCancel,
MessageBoxImage.Exclamation); //弹出确定对话框
}
}
catch (Exception)
{
throw;
}
}
结果如图所示：
弹出如下页面：
修改成功：
