【Telerik】弹出对话框RadWindow，确认删除信息

要做一个删除功能，但是删除前正常都要弹出对话框确认一下是否删除信息，防止误删信息。

点击确定按钮，删除信息；点击取消按钮，就关闭对话框，不进行删除操作。

1.Xaml页面，删除对照按钮代码。

         <telerik:RadButton BorderThickness="1" x:Name="But_Del" Click="But_Del_Click">
                    <Grid Height="Auto">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition  Width="Auto"/>
                        </Grid.ColumnDefinitions>
                        <Image Grid.Row="0"  Stretch="Uniform" Margin="3" Source="/DRGS;Component/Images/edit_remove.png" />
                        <TextBlock Grid.Column="1" TextAlignment="Center" Text="删除对照" FontSize="12" VerticalAlignment="Center"/>
                    </Grid>
                </telerik:RadButton>    

 

 2.后台代码

        /// <summary>
        /// 删除已对照关系(可批量删除)
        /// </summary>
        private void But_Del_Click(object sender, RoutedEventArgs e)
        {
            if (mdc_icd10List.Count() == 0)
            {
                RadWindow.Alert("请选择要删除的信息！");
                return;
            }

            DialogParameters dp = new DialogParameters();
            dp.Header = "删除";
            dp.Content = "确定删除此条信息吗？";
            dp.OkButtonContent = "确定";
            dp.CancelButtonContent = "取消";
            dp.Closed += new EventHandler<WindowClosedEventArgs>(OnConfirmClosed);
            RadWindow.Confirm(dp);

        }
        /// <summary>
        /// 确认删除
        /// </summary>
        private void OnConfirmClosed(object sender, WindowClosedEventArgs e)
        {
            if (e.DialogResult == true)
            {
                InterFace.IniService();
                InterFace.Service.DeleteMdcIcdListControlCompleted += Service_DeleteMdcIcdListControlCompleted;
                InterFace.Service.DeleteMdcIcdListControlAsync(mdc_icd10List);
            }
        }
        void Service_DeleteMdcIcdListControlCompleted(object sender, WcfService.DeleteMdcIcdListControlCompletedEventArgs e)
        {
            try
            {
                if (e.Result > 0)
                {
                    RadWindow.Alert("删除成功！");
                    GridDataBinding();
                }
            }
            catch (Exception)
            {
                RadWindow.Alert(e.Error.Message);
            }
            finally { MyRadBusy.IsBusy = false; }
        }

 

 

3.数据库操作（以PostgreSQL数据库为例）

        /// <summary>
        /// 批量删除
        /// </summary>
        [OperationContract(Name = "DeleteMdcIcdListControl")]
        public int DeleteMdcIcdControl(List<mdc_icd10> mdc_icd10List)
        {
            int i = 0;
            foreach (var mdc_icd10 in mdc_icd10List)
            {
                string sqlStr = string.Format(@"Delete from mdc_icd10 where id={0} ", mdc_icd10.Id);
                i += pgSqlService.ExecuteSql(sqlStr);
            }
            return i == mdc_icd10List.Count ? 1 : 0;
        }

记录完成。。。
