Data Controls :: Data Retrieval Failed For The Subreport
May 11, 2013
I am developing one Main rdlc Report Say "C" with Subreports A and B.Each report getting Data with different Datasources(DataSets).When Data is not coming for SubReports A and B, report is generated but I am getting the error message as Data retrieval failed for the subreport, 'Subreport1', located at:LocationSubTrade.rdlc. Please check the log files for more information.
private void ProcessMainReport()
{
LocalReport reportContractNote = new LocalReport();
reportContractNote.SubreportProcessing += new SubreportProcessingEventHandler(prcProcessSubReport);
reportContractNote.ReportPath = ReportPath;
ReportParameter recipientIDConsoCN = new ReportParameter(strparamRecipientIDConsoCN, RecipientID);
I have developed a application using Visual Studio 2008 and SQLServer 2008. I have a page called "Billing Center" where i need to display more than 500 records in a gridview and the gridview has sorting enabled. If i limit the page size upto 10 only the gridview performs well but user requirement is to view atleast 500 records at once which is slowing down the gridview record retrieval process.
I am using the following C# code in code behind to sorting, paging and retrieval . Please guide me what am i doing wrong in this code and how to make it work with large data set.
design pattern that works well with Visual Studio data tools against an MS SQL server; to retrieve a subset of an object's fields for all rows, and then on-demand retrieve the remainder for one row. I.E. just the small summary fields that I will serialize to a master grid view, then the larger properties including a large blob that I will render in a detail view. The performance hit from retrieving the large blob with the master result list would be too great.
The data shape is static, and I can define two separate data classes to match the specific summary vs. detail information returned. However that sounds anti-pattern-ish, to define the data classes specifically to suit the presentation layer. It also presents another problem, how to translate from the summary item to the detail item in an object-oriented way?
iam really new to Crystal Report XI Release 2..iam using multiple subreport in mainreport and onclick of particular subreport it would list out all items related to it..for example if u have customer chart(subreport) in mainreport and onclick of this it would list all customer on demand and subreport is binded and onclick of single customer it would list out single customer which sholud be passed as parameter it would get customer(full Contact details) in another subreport.if this can be done. how it can be done and explain in steps how it can be and if possible with screen shots
I was looking over the Create a Movie Database Application in 15 Minutes with ASP.NET MVC (C#), and it used entity framework and I saw this code.
[Code]....
I am just wondering, does this mean, this code actually downloads ALL the data from the SQL server for that table, and then filters where the Id matches, and then is stored in the var originalMovie? I have seen the "Linq to SQL", does this send this as sql query to the SQL server, and therefore only the relavent rows are returned from SQL server?
I am not getting data in subreport along with main report, But If I run the subreport alone I am getting data.below is the code which I am using , Please figure out my problem and give me the solution.
once executing, I am getting following error: Conversion failed when converting the varchar value 'insert into Employee(EMPID,EMPNAME,EMPLname) select ' to data type int.
how can in sql server show two columns as one column.. one of them is nvarchar and the other is int from two tables i have did this but it give error
select depart.depart_name+input_comp.no_of_depart as department,dbo.depart.depart_id from dbo.depart inner join dbo.input_comp on dbo.depart.depart_id=dbo.input_comp.depart_id group by depart.depart_name,dbo.depart.depart_id,input_comp.no_of_depart the depart_name is nvarchar datatypeand the no_of_depart is int datatype
the error is
Conversion failed when converting the nvarchar value to data type int.
i am binding the datalist using this code and store procedure. the code works fine if i pass only 1 id, but i have an array which have multiple id's separated by comma like 1,3,5, and i want to use this in the @Id parameter , but i get below conversion error: An exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll but was not handled in user code Additional information: Conversion failed when converting the varchar value '1, 3, 4, 5, 6, 7' to data type int. Code behind code is:
private void PageBind(Int32 pno) { Int32 nor, repcol; nor = Convert.ToInt32(DropDownList1.SelectedValue); SqlCommand cmd = new SqlCommand(); cmd.CommandText = "Display_Search_Records";
Currently using VS 2005 & MS SQL 2005 Server with a Windows 7 OS and I am unable to generate Update/Insert/Delete queries when using the TableAdapter wizard. I am able to create the Select statament. This is the error message that is displayed in the TableAdapter wizard on completion for each of the Update/Insert/Delete queries "failed to find or load the registered .net framework data provider"
I have seached the web but no one seems to have seen this same issue.
If you know what is causing this let me know. I didn't have this issue while running a XP or Vista OS.
I got a content place holder, in this holder, I have a grid view. Inside this grid view, I will have multiple textbox added at runtime.
From the source code, I found that one of the textbox's id is as "ctl00_CPHDetail_gvDetail_ctl02_txt_Text1", CPHDetail is the content place holder, and gvDetail is the grid view.
What I wanted to do is to find the text box control and retrieve its value.
So far, this is what I have done, and it was able to return the correct info up to the grid view. It can never find the text box control.
I wonder will it caused by the ct102 between "ctl00_CPHDetail_gvDetail_ctl02_txt_Text1"
I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField(); clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name"); BoundField bdfDescription = new BoundField(); clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description"); BoundField bdfLive = new BoundField(); clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?"); grdExisting.Columns.Add(bdfPrivName); grdExisting.Columns.Add(bdfDescription); grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result foreach (GridViewRow gvr in grdMissing.Rows) { mckbAny = (CheckBox)gvr.FindControl("ckbAdd"); mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate"); mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd"); mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove"); etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows: grdExisting.Columns.Insert(1, bdfPrivName); grdExisting.Columns.Insert(2, bdfDescription); grdExisting.Columns.Insert(3, bdfLive); It looked fine of the page, but the FindControls, all of them fail to work.
I'm getting the old "Validation of viewstate MAC failed" error when I click the submit button on my form. (Seehttp://blogs.msdn.com/b/tom/archive/2008/03/14/validation-of-viewstate-mac-failed-error.aspx) The thing is I'm getting the error even when the page is completely loaded (it can be sitting there for five minutes before I hit submit but I still get the error). This isn't even a particularly lengthy page (which is one of the preconditions). It uses a DetailsView (which I understand is another precondition for this error), but it's the only databound control on the page. Also, whenever users get this error (which is 100% of the time when they click Submit), they lose their login authentication and have to log back in. This page/site has been in use for about six months but the error suddenly started a few weeks ago without any changes being made to the code.
I get this error when I am trying to concatenate the two fields in bold into one field for a datagrid.
select count(cp.iOwnerID) as enrolled,(duration + '' + duration_interval) AS Duration ,session_id,school_id as SchoolId,program_id as ProgramId,convert(nvarchar(10),session_start_date,101) as SessionStartDate, session_class_size as SessionClassSize from dbo.cnSchoolProgramSessions cn with (nolock) left join customerproduct cp on convert(datetime,convert(nvarchar(10),session_start_date,101)) = convert(datetime,convert(nvarchar(10),cp.dtPurchasedate,101)) where record_status = 1 and school_id = '" & iSchool & "' and program_id = '" & iProgram & "' and (CP.chProductNumber = '" & Me.Label5.Text & "' or CP.chProductNumber IS NULL) group by session_id, school_id, program_id,session_start_date,session_class_size,duration,duration_interval
I've run into this bizarre situation wherein I get the below error if I set page size other than 5 in the page using this control.
"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
This GridView is a hierarchial type. I add a new GridView below each row in the webcontrol overriding OnRowDataBound.
I have gridview control. visit [URL] but when i change page index of this i get error the following error
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
In our organization we had to write code to store and retrive documents in many apps. Now I would like to write a service/library that can be used my other devs. Not sure how to start about that? What should be my first step.
I have been following various guides online and they seem to be great and i learning a great deal and i have my learning set out however i have come across a stumbling block "yet again"
I was following Mikes SQLce image upload guide and I got it, I understood it all "in theory"
[URL]
however what i couldn't figure out is when i want to display that image on a separate page or pull it back into a webgrid it just showed me SystemByte[] and not the image. Or a long string of writing that started -System........
I tried stripping Mikes code thinking well he is pulling the Image from the DB once the postback is done so why cant I do it on another page or in another <Div>. ?
If im not mistake it has somthing to do with this line
I had a web application. We needed to move it to anotherserver, after we moved that, the membership database (aspnetdb) did not work.....finally i solved the problem, and now I have another problem. although in the web.config enablepasswordretrieval is set to true, and the type is clear, i get error in password retrieval.
