silverlight系列(子窗口创建、引用webservice)

一、ChildWindow:

ChildWindow相关部件

• Chrome:围绕在子窗口内容四周的框架
• CloseButton:子窗口标题中的关闭按钮
• ContentRoot:弹出窗口的根，包括Chrome和ContentPresenter
• Overlay:在子窗口打开时覆盖父窗口的控件部件
• Root:控件的根

MainPage.cs:

[Category("ChildWindow")]
private Childwindow childwindow;

public MainPage()
{
    InitializeComponent();
    childwindow = new Childwindow();
    childwindow.Closed += new EventHandler(window_Closed);

}

private void window_Closed(object sender, EventArgs e)
{
    if ((bool)childwindow.DialogResult)
    {
       if (childwindow.Title.ToString().Trim() == "添加新文字元素")
       {
          CreateWordElement(childwindow.tbTextInfo.Text.Trim());
       }
       else
       {
          CreatePicElement(childwindow.lbxPic.SelectedItem.ToString());
       }
     }
}

/// <summary>
/// 生成文字元素
/// </summary>
/// <param name="strtext"></param>
private void CreateWordElement(string strtext)
{
}

/// <summary>
/// 生成图片元素
/// </summary>
/// <param name="strpic"></param>
private void CreatePicElement(string strpic)
{
}
private void btnAddElement_Click(object sender, RoutedEventArgs e)
{
   childwindow.Title = "添加新图片元素";
   childwindow.Show();
   childwindow.tbtype.Text = "选择图片：";
   childwindow.lbxPic.Visibility = Visibility.Visible;
   childwindow.lbxPic.ItemsSource = listPic;
   childwindow.tbTextInfo.Visibility = Visibility.Collapsed;
   childwindow.lbxPic.SelectedIndex = 0;
}

ChildWindow.xaml:

ChildWindow.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace DragElement
{
    public partial class Childwindow : ChildWindow
    {
        public Childwindow()
        {
            InitializeComponent();
            optionsStack.DataContext = this;
        }
        
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", 
            "CA1811:AvoidUncalledPrivateCode",Justification = "Used by event defined in Xaml.")]
        //取消报告特定的静态分析工具规则冲突，允许一个代码项目上应用多个取消报告设置
        private void OKButton_Click(object sender, RoutedEventArgs e)
        {
            this.DialogResult = true;            
        }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", 
            "CA1811:AvoidUncalledPrivateCode", Justification = "Used by event defined in Xaml.")]
        private void CancelButton_Click(object sender, RoutedEventArgs e)
        {
            this.DialogResult = false;
        }

        private void tbTextInfo_GotFocus(object sender, RoutedEventArgs e)
        {
            
        }
    }
}

运行效果：

点击按钮新添加图片元素：

 

点击确定按钮：

二、调用webservice

1.创建webservice:

SaveXml.asmx:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;

namespace DragElement.Web
{
    /// <summary>
    /// SaveXml 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
    // [System.Web.Script.Services.ScriptService]
    public class SaveXml : System.Web.Services.WebService
    {

        [WebMethod]
        public bool  SavemyXml(string str)
        {
            try
            {
                string UpdateSQL = "update flow set xmltext='" + str + "' where flowname='设计器1'";
                SqlConnection conn = new SqlConnection(ConfigurationManager.
                    ConnectionStrings["flowdata"].ConnectionString);
                SqlCommand comm = new SqlCommand(UpdateSQL, conn);
                conn.Open();
                comm.ExecuteNonQuery();
                conn.Close();
                return true;
            }
            catch
            {
                return false;
            }
        }
    }
}

2.给web添加固定端口

 

3.给silverlight项目添加服务引用
