c#, mysql in my project.
In that i create a rdlc report. I dont know to pass winform textbox value to rdlc report text field.
I googled and try some set of code. but cant get that.
If you worked in report. please help me.
My requirement is,..
I am doing college project. In that they asked bonafide certificate. So i create a winform With reportviwer, name, course, year, semester, academic year, purpose textboxs and one button. Click the button when the textboxes are filled. those text values want to pass the record textboxes.
Is it possible any way.
my report...
Set the parameters using LocalReport property in the Report Viewer
C# Code :
ReportParameterCollection reportParameters = new ReportParameterCollection();
reportParameters.Add(new ReportParameter("ParameterName", "Value"));
this.reportViewer.LocalReport.SetParameters(reportParameters);
One way would be to setup a parameter for each of the fields you want to bring in and set the value of the parameter to whatever you want in your C# app. In the report you would then set the value of each text box to be the parameter and it should work just fine.
Or if you are using RDLC files (which you are) you could put your data into a dataset and pass that to the report and then have each field in the report a column in the dataset
1) Create parameter in RDLC Report.
2) Place the parameter Where you want in the RDLC Input Textbox property.
3) Type the below code in Reprot.cs page.
4) Passing the parameter value where you redirect the Report page.
ReportParameter[] parms = new ReportParameter[n];
parms[0] = new ReportParameter("param_name", textbox(n-1).text);
parms[1] = new ReportParameter("param_course", textbox(n).text);
this.reportViewer1.LocalReport.SetParameters(parms);
this.reportViewer1.RefreshReport();
following method worked for me i used vb.net2010
1: In Visual Studio 2010, open your .rdlc file, and open “Report Data” window (If you can not see this window, go to View menu to open it);
2: Right click the “Parameters” node, and add a new Parameter, ie: named it “startdate“;
3: In your .rdlc file, add a textbox, named it tbContent, and set its filed express to :
=Parameters!startdate.Value
4: Go to your Form file which include your reporterview control, and add the following code:
Dim rptparameter As ReportParameter
rptparameter = New ReportParameter("content", txt_startdate.Text)
rv_param.LocalReport.SetParameters(New ReportParameter() {rptparameter})
rv_param.LocalReport.Refresh()

I am trying to do a simple thing. I want the user to enter the date on a form and for the report viewer to show a report reflecting the transactions of that date. Using Crystal Reports, I have created a parameter of type date. I put a selection formula referencing that date and ran it. I get a flash of the report viewer followed by a screen that asks for the parameter. I enter the parameter and the form closes. So I tried dropping the record selection formula. The same thing happens - the form opens, asks for the date then closes when I hit OK and closes the form. I think the problem is the way I'm calling it. Please take a look and kindly help if you can:
reports.BalanceDetail report = new reports.BalanceDetail();
crystalReportViewer1.ShowLogo = false;
crystalReportViewer1.ReportSource = report;
report.SetDataSource(MSDataSet);
crystalReportViewer1.Refresh();
crystalReportViewer1.Show();
Create a parameter in the crystal report and generate a formula field based on this parameter.
I use vs 2010 and telerik reporting 2013 Q1
use the next code to bind a datatable to report.
Reports.Report1 report = new Reports.Report1();
Telerik.Reporting.ObjectDataSource objectDataSource = new Telerik.Reporting.ObjectDataSource();
objectDataSource.DataSource = CreateData().Tables[0];
report.DataSource = objectDataSource;
Telerik.Reporting.InstanceReportSource reportSource = new Telerik.Reporting.InstanceReportSource();
reportSource.ReportDocument = report;
TelRptViewer.ReportSource = reportSource;
My report contains a simple table dataitem with 3 columns.
I have already read this topic in help.
Working With Data at Design Time-Data source available only at runtime
"This approach is useful when you cannot get the report's data source at design time or want to avoid loading real data into Visual Studio at design time. In this case you would have to mock your data just to enable the Report Designer to show any data schema. This will enable you to adjust the layout of the report and bind report items to the available data fields, while the real data will be loaded only at runtime either in NeedDataSource event or in the actual application. "
In simple reportviewer there was an xsd which prove the data schema for report.
In this viewer how its is possible to make this data schema or similar? Or there is another way to do this?
Thx.
You never said whether you have added report items (e.g. TextBoxes) in your Report1 class. Those textboxes need to have binding expressions as Value i.e. = Fields.MyDataColumn1.
Only then, would the report actually show data. You could also add a call to TelRptViewer.RefreshReport(); which is required for some viewers (e.g. Windows Forms)
Good luck!
You can bind Telerik Reports to objectdatasource at design time and drag your fields directly to the REport using Visual Designer
To create and run the reports using Visual Studio or the new Desginer while binding it to a objectdatasource : All you have to do is hardcode the connection string into the class of your data method . and inside that method use the connection string. Check my blog: http://flying2mind.blogspot.com/2013/10/creatingrunning-telerik-reports-in.html

Basically, you can add your datasource code in NeedDataSource event of your report and set the datasource. NeedDataSource event is used when there is no data source for the report.
private void Report1_NeedDataSource(object sender, EventArgs e)
{
Telerik.Reporting.Processing.Report rpt = (Telerik.Reporting.Processing.Report)sender;
this.Report1DS.Parameters[0].Value = your value to be passed to data source..;
// Similarly you can add more values of parameters.
rpt.DataSource = Report1DS;
}
I have two datasets I need to pull from, A base that both reports use and then a separate one that only one report pulls from. I get the error
Error 12 The Value expression for the text box ‘Textbox9’ refers to
the field ‘Name’. Report item expressions can only refer to fields
within the current dataset scope or, if inside an aggregate, the
specified dataset scope.
My best guess is I have to associate them with the correct dataset but I have not been able to find any documentation on this.
edit: I am trying to access property files that I created for the fields on the report document.
Can someone please tell me where in the rdlc document I need to code something like name.value, "dataset1" or something similar?
When you create a table in a RLDC, in the Tablix properties (selecting a row or a column) you must associate a DataSet.
After doing that, you have to write in each cell the name of the field (in the dataset) that you will use. You can do that by clicking on the "little table" in the cell, when you put the mouse over it
In images (with Visual Studio 2010)
If you don't see the dataset in the list, you must add it.
For that, click on view menu -> report data.
Then, in the DummyDataSource, click Add Dataset..
And select it from the list, or create a new one instead, in the same form.
If this doesn't work, well I don't know haha
If the two datasets has the same structure, then you could use one just, and in the code assign it to the datasource
I ran into this same error and the only way I could resolve it was by closing and reopening BIDS and then refreshing the fields from the stored procedure (Right click the data set -> Dataset Propoerties -> Query -> Refresh Fields).
Thanks for the troubleshooting tips!
If you are trying to embed the results of one set into a table that is using another data set, have you considered a subreport?
After some careful research and error checking I found that I had to create my base model property file and when I drag the actual data points on to my form I had to associate them with their correct set:
I clicked the value and associated the correct dataset.
I am new to RDLC reports in Visual Studio 2010.
I am working on a Website, in this I have used report feature of VS2010. I use ReportViewer to show Report1.rdlc. It is showing it perfectly. Now my requirement is to filter data in report at runtime. I go through this question but not able to understand it's answer.
Because Report1.rdlc is not available in code behind.
Now, how can I filter report's data at runtime?
Surely you assign the dataset to the rdlc report, and in the page of your reportviewer, you would be using an object datasource (and therefor an XSD dataset with datatables), which encapsulates the query.
The query naturally has a where clause, in which you insert your parameters to filter the data by, like:
WHERE (Table.Field = #Param OR #Param = A_Default_Value)
Now add the controls you like to the page before calling the report (drop-down lists, textboxes, etc..), those controls filter the Object datasource, which is mapped to a dataset in the rdlc report, and thus, the report would be filterd upon clicking on a certain button, e.g. Show Report, to refresh the object datasources (databinding them) and re-showing the report in the reportviewer.
You may consider assiging the values of the filtering controls to parameters in the rdlc, so that you may show the parameters of the report in its header upon generating it:
Parameters!ParameterName.Value
Hope that helps you.
How are you getting the data from Server, etc. Are you binding to a datatable result? If so, you can just have your query apply the filter when extracting data to begin with so you don't have to do anything special in the actual report.
Per your feedback, if you are getting a DataTable, then applying a filter should be easy like
DataTable oDT = YourSQLCommandToGetData();
oDT.DefaultView.RowFilter = "SomeColumn = x and OtherColumn = y";
And then run your report. If you want to take it to another level and ENSURE you don't have any unwanted records, you could even do something like
DataTable oNewFilteredResult = oDT.DefaultView.ToTable();
Then, you can assign the NEW table to call the RDLC.
I'm taking a look now to XtraReports reporting tool and there's something that I don't get it yet.
How do I set the data source for a certain field (showed in the report as a Label I guess), without having to build a connection, adapter and dataset at design time but doing it programatically.
For example, I can have a table called "User" with 3 fields: UserId, Username and Password.
In the report designer I place 3 labels (and here's my question) set the datasource for showing the 3 database fields.
Then, in the code behind, I create a connection, execute a command, fill a dataset, create a report instance, pass the datatable to it and show the report preview.
Is this possible? Let me know if it isn't clear enough.
Thanks!
You could set your Report's DataSourceSchema property to an XML schema that represents your DataSource. That will let you use the Report Designer to set your data bindings at design time without establishing a connection to the database each time.
Here's how I do it:
Once I have my report query mostly finalized, I run the code once with a call to
myDataSet.WriteXml("C:\myDataSourceSchema.xml", System.Data.XmlWriteMode.WriteSchema)
Then in the report designer I set the Report's DataSourceSchema property to the newly created file. This will populate the Report Designer's Field List tab so you can bind at design time. That way you only have to have a valid data source once (or any time you change your columns). You can definitely still do Przemaas's approach and do all of your data bindings in code, but I prefer to let the designer handle most of the work.
Building a report without a dataset, you would use an IList object ... so follow this nice tutorial
How to: Bind a Web Report to an Array List
https://documentation.devexpress.com/#XtraReports/CustomDocument3851
Yes, it is possible. You can define necessary databindings in the code:
this.xrLabel1.DataBindings.Add(new DevExpress.XtraReports.UI.XRBinding("Text", data, "Name", "aaa"));
Text here is property on the XrLabel
class. I assume that you want to
display bound field as text in label.
data is your object with data
"Name" is name of field that you want to display
"aaa" is display format, applicable in case you want to display values with custom formatting
Basically databindings in XtraReport act pretty much the same way as standard windows forms databindings.
Let me know is you need more guidelines
Here is an alternate..
rtpObject.DataSourceSchema = dataSet.GetXmlSchema();
before doing this set modifier property as public
InvoicePrinting_Rpt InvoicePrintingRpt = new InvoicePrinting_Rpt();//report object
InvoicePrintingRpt.BillDetails.Report.DataSource = ds_Invoice;
InvoicePrintingRpt.Report.DataMember = ds_Invoice.Tables[0].TableName;
//bellow third parameter as your column name.
InvoicePrintingRpt.lbl_BillHead.DataBindings.Add("Text", null, "BILL_DESCRIPTION");
InvoicePrintingRpt.lbl_Det_Date.DataBindings.Add("Text", null, "TRANSACTION_DATE");
InvoicePrintingRpt.lbl_ISINCode.DataBindings.Add("Text", null, "ISIN_CODE");
ReportViewer1.Report = InvoicePrintingRpt;//assign report obj
ReportViewer1.Report.Name = "DevExpress_Reports.InvoicePrinting_Rpt";
ReportViewer1.DataBind(); //binding
XRBinding binding = new XRBinding("Text", ageingBindingSource, "ageing_contactsLookup.name");
this.xrLabel19.DataBindings.Add(binding);
// or //
XRBinding binding = new XRBinding("Text", dbaDataSet, "transactions.fk_transitems_transactionid.name2");
this.xrTableCell1.DataBindings.Add(binding);
