ASP.NET中ReportView与IE11兼容性解决方法
ASP.NET #reportview2014-04-05 11:11
1.查询时报表出错:
在报表模板中加入了“横线”控件所致,删除即正常了。
2.报表控件上不显示打印按钮:
原因:
由于ReportView的打印功能是依赖于一个RSClientPrint的ActiveX控件的,而ActiveX只能运行在IE浏览器上。
微软改变了IE11的User-Agent
IE11:User-Agent Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
IE10:User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)
致使ReportView控件服务器端判断当前的IE11浏览器为非IE浏览器,没有发送创建“打印”按钮的相关js代码,所以没有显示打印按钮。
解决:
在网站根目录下创建App_Browsers目录加入browser文件。
<browsers> <browser id="IE11" parentID="Mozilla"> <identification> <userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" /> <userAgent nonMatch="IEMobile" /> </identification> <capture> <userAgent match="Trident/(?'layoutVersion'\d+)" /> </capture> <capabilities> <capability name="browser" value="IE" /> <capability name="layoutEngine" value="Trident" /> <capability name="layoutEngineVersion" value="${layoutVersion}" /> <capability name="extra" value="${extra}" /> <capability name="isColor" value="true" /> <capability name="letters" value="${letters}" /> <capability name="majorversion" value="${major}" /> <capability name="minorversion" value="${minor}" /> <capability name="screenBitDepth" value="8" /> <capability name="type" value="IE${major}" /> <capability name="version" value="${version}" /> </capabilities> </browser> <!-- Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11,0) like Gecko http://yige.org/--> <browser id="IE110" parentID="IE11"> <identification> <capability name="majorversion" match="11" /> </identification> <capabilities> <capability name="ecmascriptversion" value="3.0" /> <capability name="jscriptversion" value="5.6" /> <capability name="javascript" value="true" /> <capability name="javascriptversion" value="1.5" /> <capability name="msdomversion" value="${majorversion}.${minorversion}" /> <capability name="w3cdomversion" value="1.0" /> <capability name="ExchangeOmaSupported" value="true" /> <capability name="activexcontrols" value="true" /> <capability name="backgroundsounds" value="true" /> <capability name="cookies" value="true" /> <capability name="frames" value="true" /> <capability name="javaapplets" value="true" /> <capability name="supportsCallback" value="true" /> <capability name="supportsFileUpload" value="true" /> <capability name="supportsMultilineTextBoxDisplay" value="true" /> <capability name="supportsMaintainScrollPositionOnPostback" value="true" /> <capability name="supportsVCard" value="true" /> <capability name="supportsXmlHttp" value="true" /> <capability name="tables" value="true" /> <capability name="supportsAccessKeyAttribute" value="true" /> <capability name="tagwriter" value="System.Web.UI.HtmlTextWriter" /> <capability name="vbscript" value="true" /> </capabilities> </browser> </browsers>3.打印按钮显示出来后,打印不了:
原因:
由于ReportView在页面生成时并不直接加载RSClientPrint控件,而是在点击打印按钮时由JS动态添加OBJECT元素来加载RSClientPrint控件,问题就在这里。
原来IE11在添加OBJECT元素后并没有从服务器端加载RSClientPrint控件,所以打印无效。
解决:
在aspx页面中直接加入OBJECT元素。
<%if(Request.Browser.Type.IndexOf("IE11")>-1){%> <object id="ReportViewer1_PrintObj" classid="CLSID:5554DCB0-700B-498D-9B58-4E40E5814405" codebase="http://yige.org/Reserved.ReportViewerWebControl.axd? Culture=2052&CultureOverrides=True&UICulture=2052&UICultureOverrides=True&ReportStack=1& ControlID=57e8d903ef7748f7a0c02a1c6bdb851d&Mode=true&OpType=PrintCab&Arch=X86#Version=2009,100,1750,0" style="display: none;" VIEWASTEXT=""></object> <%} %>
注意:object 的id="ReportViewerID"_PrintObj,codebase=路径,可能由于控件版本的不同而和本例不同。
