I'm having some problems with reporting and I thought you could help me:
I have created a dataset (mydata.xsd). I also have designed a Report.rdlc, and I did the same with a frame with a ReportViewe inside, wich use mydata.xsd as a source data.
I have designed mydata.xsd to have 2 columns (user, time). How would you fill this dataset? The reporting tool get the data from this "xsd" file, but I never fill it anywhere. I fill another dataset I have as a private member of my class, and that's all.
Thanks in advance.

What dataset are you filling and from what dataset are you want to fetch records ? If u have two columns say user and time then create a dataset with wizard , it will generate the queries and tables. Now set this dataset as the datasource of report. From Field Explore drag drop the column to report.

Hi i want to create a rdlc report with a table in it such that the table have two columns. the first columns is hard coded during design and describe label of values in next column. The next column should be filled by values coming at run time.
Report format
.Creating this table with no database gives me error that
"the tablix "table1" refers to an invalid dataset name which does not exist"
Is there anyway to fill values in next column without creating a data set?
if not then can/how I create a mock data base but values in column still be filled by parameters?
You can add a empty dataset to your reports like this:
Add a object DataSet to your report if there aren't any, the object can be anything as this does not matter.
Then add these line before rending the report:
ReportDataSource rdl = new ReportDataSource("DataSet1", new List<string>());
ReportViewer1.LocalReport.DataSources.Add(rdl);
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.
Until now I am using a DataSet and a single DataTable, to gather data from my database add rows to the table and display it to the report. Something like that:
report.SetDataSource(ds.Tables[1]); //ds(DataSet)
Is there any possible way of adding multiple DataTables to the DataSet and display each table into a new page to the report in a single document?
Thanks for your time
I have a table in my dataset that I create it in dataset design view in Visual Studio 2010. Then in my XtraReport1 class I have some labels that refer to these table columns. At the beginning this table is empty. When program is run, this table fill with with data, and then i make a new XtraReport in my code and call .ShowPreviewDialog() for it to show report. But it's empty and there is no error. Where i don't understanding ?
XtraReport1 report = new XtraReport1();
report.ShowPreviewDialog();
I think when I new up a XtraReport in my code and ShowPreviewDialog, in this specific time XtraReport look at dataset and get its data. Am I wrong? I'm sure that table that XtraReport is using is full with data because I show its data in exact time in a GridView - the GridView has data but the XtraReport doesn't!!
Answer is what Davide Piras said in comment : You are not associating the datatable to the report object. before calling the showpreview assign it to the report datasource
In my project, I want to give a report. For that i create a report with dataset.
name, course, year, semester all the textbox datas are passing from form. (I am using parameters to passing the data). but the table datas are taken from dataset. In that dataset have all the student data. But i want display one particular student data.
For that i want to filer the data at run time in rdlc report. How can i filter the data?.
My Form
Report Design
Mysql Table:- In that admin_no column is there. I planed to filter the data with the help of admin_no.
Thanks in advance!.
Filter Datatable in DataSet using Select method and put returned data to another table and pass the table to the report
