Until this i can fill the report with the proper data but how couli do it with a subrportĭs.DataSetName = reportPath = and Settings\.\Report1.rdlc" //full path Me.(New ReportDataSource(dsname, ds.Tables(dstable))) Me.()ĭstable = ele.Item("rd:TableName").InnerText Nlist = d.GetElementsByTagName("DataSet") 'I get the data for the datasource from the rdlc file #How to update dataset in rdlc parameters code#Here is my code and Im filling the dataset with a xml file just for test:ĭs.ReadXml("D:\SubreportInList\Orders.xml") #How to update dataset in rdlc parameters how to#I have done a report class based on your ideas and article but when i try to load a subreport i dont know how to pass the same dataset to subrepor i can see the data in the main rerpot but in the subreport a get a error. Throw new Exception("Error in base64Decode" e.Message) String result = new String(decoded_char) Utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0) Int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length) Ĭhar decoded_char = new char utf8Decode = encoder.GetDecoder() īyte todecode_byte = Convert.FromBase64String(data) Throw new Exception("Error in base64Encode" e.Message) String encodedData = Convert.ToBase64String(encData_byte) Public string readTextFileIntoString(string filePath)īyte encData_byte = new byte ĮncData_byte = 8.GetBytes(data) Rdlc = readTextFileIntoString(rdlcFilePath) How could I read the rdlc file as remote xml? The problem I have is that now I want to do the same with a server report using (" To read a remote xml i use:ĭim wr As Net.HttpWebRequest = CType((" Net.HttpWebRequest)ĭim resp As Net.WebResponse = wr.GetResponse()ĭim stream As Stream = resp.GetResponseStream()ĭim reader As XmlTextReader = New XmlTextReader(stream)īut i get an Exception saying that "error 404 server not found", However if i change " for " i Dont get any Exception and i get the xml structure. I do this with the ("file.rdlc") and read the rdlc as xml this a Xmldocument.read("filepath") I read the rdlc as a xmldocument to get the datasets and a tables in order to use those data to create a Datasoruce. Once we have the Report- DataSet pair, we can display any report we want. Before We BeginĪs I've said before, in order to display a report, we need a DataSource (in this article, a populated DataSet instance) and a report document ( *.rdlc file ). So what we need is some kind of a Report Import / Generic Report Display ability. In the maintenance phase, it is costly to distribute a whole update that often. After distributing and deploying the software, organization must give supporting service about newly added or changed reports. #How to update dataset in rdlc parameters software#My organization is developing accounting software and in accounting domain there are lots of changes in reports. I'm currently in need of a component that displays generic reports. But what if you don't have access to DataSet objects during design time, what if the overall architecture of the software doesn't let you to use SQL statements or connection strings on the architectural level you are currently working, what if you need to use data without knowing its structure until runtime, what if you need dynamic data sources rather than static? Probably, these solutions cover most of the situations a developer can encounter. Some others used TableAdapter objects that include SQL statements and/or Connection strings, etc. Most of them assumed DataSet objects are accessible during design time. This article presents how to form a Report Display Component to display data within different DataSet objects that are described by a Report document ( *.rdlc).ĭuring my previous searches about displaying data within generic DataSet objects, I've encountered a set of different solutions. In order to display a report by using ReportViewer Control, we need a DataSource that contains the data to be shown and a Report document that describes how that data should be displayed.
