Infopath web浏览中的多项选择功能

因为Infopath web浏览没有提供多项选择功能，如果需要这个功能，解决方案是：

用Repeating Table来实现

从某个数据连接中读出要显示的数据，然后用重复表的形式显示出来。

例程：

if (!this.New) return;
            XPathNavigator root = MainDataSource.CreateNavigator();

            DataSource myDataSource = this.DataSources["DS1"];
            XPathNavigator t1 = myDataSource.CreateNavigator();
            XPathNodeIterator t2s = t1.Select("dfs:myFields/dfs:dataFields/d:DS1",NamespaceManager);

            XPathNavigator options = root.SelectSingleNode("/my:myFields/my:options", NamespaceManager);
            XPathNavigator optionFirst = root.SelectSingleNode("/my:myFields/my:options/my:option", NamespaceManager);
            XPathNavigator myText;

            myText = optionFirst.SelectSingleNode("my:Text", NamespaceManager);
            string c2;

            while (t2s.MoveNext())
            {
                XPathNavigator myOption = optionFirst.Clone();
                myText = myOption.SelectSingleNode("my:Text", NamespaceManager);
                c2 = t2s.Current.GetAttribute("C2", "");
                myText.SetValue(c2)
                options.AppendChild(myOption);
            }          
           optionFirst.DeleteSelf();

options是重复表，包含两个节点：selected和text，selected是布尔型，text是多选框对应的文字
