this is the first time I have tried this so I am probably missing something that is staring me right in the face.
I have an ASP.NET page where the user fills in a request which then emails a PDF rendered from a ReportViewer instance.
It all works fine when I run it locally through the ASP.NET localhost but when I try and run it of the webserver it fails with the following message:
An error has occurred during report processing.Cannot create a connection to data source 'DataSource1'.
I can preview the report via the web based report manager via http://servername/reports which works without any problem and using the report editor in VS2005.
I suspect it is something to do with the credentials but I am at a loss. The data source is set with a username and password but this is saved within the datasource.
I think I'm getting mad here...I thought this should be super simple, but I just can't figure out how to do that.This is what I'm trying to do:I want to create an rdlc report using the ReportViewer control in ASP.NET 4 (VS 2010), and, as its datasource, use a class with some properties.I tried everything I can think of, but I just can't figure this out. All the docs I found state that the object should appear in the DataSource pane of the website, but I can't make it appear there.I would like the fields of the class to appear in the report desiger so I can use them - but I can't do that either.Using the designer, I can only define new dataset - I don't want to use dataset, but business objects!So - how can I do that? Do I have to use some kind of DataSource control? How can I make the report designer know about the business object?
I have a reportviewer (Microsoft.ReportViewer.WebForms) control on my page. All my reports use one data source. I want to be able to let my reports run on a different database when started from my UAT enviroment. So the location of the reports is the same, but the data comes from a different db. I cannot seem to find how this is done, is it even possible?
EDIT: They are server reports on SQL Server . I know you can set the dataset programmaticaly but I just want the reports to point to a different db and leave the rest of the report intact.
How can I use a web service (WCF) as the data source for a reportviewer . I create web application in that i want use .rdlc ( dont want .rdl) so i write wcf service . How to link wcf service into reportviewer to display data in rdlc.
I have a reportViewer control and I dynamically setting the report path and dataset in the page load event if it is not a post back. This first report displays without issue. However, when I attempt to change the report path / dataset via the onChange event from a dropdown list I get the following error:
A data source instance has not been supplied for the data source "Summary_DataTable1".
This code works fine and the summary report is displayed the first time the page is loaded.
My web form reportviewer control can't seem to find my sub report. When I debug, it gives an error message in the report that states the report can't be found at file path for the sub report. If I copy and paste the path out of the error into the address bar of windows explorer, the report opens right up. I am using VS 2010, the 4.0 framework, and windows 7.
I have a form in which i have written onSubmit calling a javascript function. in that javascript function how can i check that who was the event generater ( i mean on which button click this even raised)..
Note: onsubmit function call is in form tag..
i am using JavaScript and asp.net
My code is like this:
[code]...
i dont want to change any functionality.. i have got a dropdownlist which is causing postback.. i want that when this dropdownlist raise post back either i should know that its raised by dropdownlist or that function should not be called by dropdownlist's postback
Code: Try LoggerWrite("EX - Message: " & Ex.Message.ToString, "ErrorLog") Dim myDE As DictionaryEntry If Ex.Data.Count > 0 Then For Each myDE In Ex.Data LoggerWrite(" EX DictionaryEntry: Key = " & myDE.Key.ToString & " Value = " & myDE.Value.ToString, "ErrorLog")

The user is getting a 500 internal error occurred. What he is trying to do is create a datagrid. The error only happens when there are a lot of data used to build the grid. But why exactly is it too much data? And can I increase a buffer or set something in a config file to allow all the data? The data come from a web service.
how to get source control explorer in visual studio 2008 team edition.i followed this ... View > Other Windows > but i cant find source control explorerI have downloaded SVN .tortoise svn me how to use as well, any articles for that..
I work in a group of 4 .Net developers. We rarely work on the same project at the same time but it does happen from time to time.We use TFS for source control. My most recent example is a project I just placed into production last night that included 2 WCF services and a web application front end. I worked out of a branch called "prod" because the application is brand new and has never seen the light of day. Now that the project is live, I need to branch off the prod branch for features, bugs, etc...
So what is the best way to do this?
Do I simple create a new branch and sort of archive the old branch and never use it again?
Do I branch off and then merge my branch changes back into the prod branch when I want to deploy to production?
And what about the file and assembly version. They are currently at 1.0.0.0. When do they change and why? If I fix a small bug, which number changes if any? If I add a feature, which number changes if any?
What I am looking for is what you have found to be the best way to efficiently manage source control. Most places I have worked always seem to bang heads with the source control system in on way or another and I would just like to find out what you have found that works the best.
When I use Project Reference to add dependent assemblies to my C# library project, I can use the "Go To Definition" popup menu item to go to the source file of the class defined in the dependent assembly. That is one of the most useful features of VS for me. However, when I add dependent assemblies as BIN References (via the Browse tab of the Add Reference dialog), I only get the class definition generated from metadata of the dependenat assembly, not the source file.
I realize that intellisense can't find the source directory of the dependent assembly, but where can I enter the directories so intellisense would know? There is a "VC++ Directories" page in the Options->Projects and Solutions dialog, but that is only for C/C++ projects. There should be one for C# as well. The bigger mystery is when I put my project in the debugger, I can step into methods defined in the dependent assembly and see its source file. Why could the debugger find the source file but not intellisense?
I am writing an application in which a remote url web site ( says url1 that is sender) sends xml data to another web site (says url2 that is receiver) by using .NET WebRequest. On the receiver url2 if I use .NET Page.Response and .NET Page.Request to store posted/received xml data into an external text file, then the data is stored. However, if I store the received data into database, I do not see the data is stored into the database.
trouble shoot the codes so I can store such remotely posted data into database on the receiver side url2.
I host both url1 site and url2 site in my computer using IIS like [URL]
1/ Receiver page's codes that store remotely posted xml data into database do not work:
protected void Page_Load(object sender, EventArgs e) { Page.Response.ContentType = "text/xml"; StreamReader reader = new StreamReader(Page.Request.InputStream); String xmlData= reader.ReadToEnd(); ProductNameSapce.ProductCollection.InsertReceivedProduct(xmlData).ToString(); // data is not stored ; the method is tested and works well with hard-coded data reader.Close(); Page.Response.End(); }
2/ The version of the receiver page at url2 that stores into an external text file works:
protected void Page_Load(object sender, EventArgs e) { Page.Response.ContentType = "text/xml"; StreamReader reader = new StreamReader ( Page.Request.InputStream ); String xmlData= reader.ReadToEnd (); StreamWriter s; s= File.CreateText ( Server.MapPath(".")+@""+ Guid.NewGuid () + ".txt" ); s.WriteLine ( xmlData); // data is stored in an external text file s.Close (); reader.Close(); Page.Response.End(); }
I have built an ASP.NET (.NET v4) application in VS 2010. It is working just fine. But when I try to create deployment package (so I can deploy it in our test IIS 7.5 Server), it gives me error like this,
Error 1 Could not open Source file: Could not find file 'C:11-2 estobjDebugCSAutoParameterize ransformedWeb.config'. 0 0 test
Thing is in past, I had deployed the SAME application using the SAME method.
I don't know it happen just to me or Others have the same situation too . All the time when i bind a DataControl to an ObjectDataSource in "Configure Data Source" wizard of ObjectDataSource,when i set parameter source as "Control" in "ControlId" DropdownList there are TWO Item of every control in the WebForm , while it make sense be one.
I have a requirement to design an ASPX page to receive a binary image from a remote call. Basically, our client wants to send a POST request from their server to this particular page. This POST request contains some parameters, as well as an JPG image. How should I design this ASPX page to receive all these information? I need to convert the JPG image to byte[] array and save it to DB, together with the rest of the parameter values.

I have a site that i have developed in asp.net. On debugging the site now hosted using iis7 i noticed a bug, i cannot reproduce this when i run it locally in vs, meaning i can't see the error. The bug occurs on the check box changed event of a devexpress check box. It connects to the database using devart.postgres sql component and linq. However, this is the same connection as anywhere else in the project. The same code works elsewhere in the project. The error i get is:
the requested name is valid, but no data of the requested type was found.
part of my code is in an if statement that checks if a textbox is blank if so it does not run the code within the if statement, interestingly enough if the text box is blank the code runs, so it must be in the if statement? i commented out all of the code and tried again and it still would not run.
