infopath:InfoPath 上传多附件解决思路方法
效果图就是这样了下面来看看终点代码部分
代码部分主要技术点就是infopath附件分解和对infopath重复表操作
命名空间引用
usingMicrosoft.Office.InfoPath;
using;
using.Xml;
using.Xml.XPath;
using.Windows.Forms;
using.Text;
首先是注册两个按钮事件
编写上传按钮事件主要处理是文件分解上传以及重复表删除增加
删除事件主要处理了对文档库文件删除以及infopath表单重复表行删除都是比较基本操作
到这里基本东西就是这些了有关infopath表单设计这里就不提了

((ButtonEvent)EventManager.ControlEvents["CTRL18_5"]).ClickedClickedEventHandler(CTRL18_5_Clicked);

XPathNodeIteratorrows1;
myNamespace=NamespaceManager.LookupNamespace("my");
while(rows.MoveNext)
{
rows1=domNav.Select("/my:myFields/my:group6/my:group7",NamespaceManager);
attachment=rows.Current.SelectSingleNode("my:attachment",NamespaceManager).Value;

}
删除事件主要处理了对文档库文件删除以及infopath表单重复表行删除都是比较基本操作
publicvoidCTRL18_5_Clicked(objectsender,ClickedEventArgse)
{
//在此处编写代码
strfileUrl=e.Source.SelectSingleNode("/my:myFields/my:group6/my:group7/my:fieldURL",NamespaceManager).Value;
SPSecurity.RunWithElevatedPrivileges(delegate
{
try
{
using(SPSitemySite=SPSite("http://ascentn-moss:8080"))
{
mySite.AllowUnsafeUpdates=true;
SPWebwebs=mySite.OpenWeb;
webs.AllowUnsafeUpdates=true;
webs.GetFile(strfileUrl).Delete;
}
}
catch(Exceptionex)
{
throwex;
}
});
e.Source.DeleteSelf;
}
