I need to add a second DataTable from our app's main DataSet into a report, but not having much luck.
We have several simple local reports in RDLC files, each with a single DataTable based on a view in our application DB. I need to improve one of the reports to add information from another table. This other table is defined in the same core DataSet which we use for reports in our .NET 2.0 WinForms application. Since the two tables are in the same DataSet, can I just make sure that both tables are loaded into the DataSet and then point the report at the DataSet instead of the DataTable? Something else?
Needless to say, I've been playing around with this for a while and not getting anywhere.
TIA,
Matt
OK, I got this working and, in retrospect, it was pretty easy. I just didn't know which menus to use for getting VS to hook everything up, and which order to do them in.
Looking at the Designer.cs for my form was actually the most helpful thing I did. I noticed was that the ReportViewer has a default BindingSource pointed at the first table. Originally, I was hung up on trying to give the BindingSource a DataSet instead of a DataTable, but then I decided to try making a second BindingSource instead.
Maybe there's a better way, but here's basically what I ended up doing:
With the RDLC in the designer, clicked the Report menu then Data Sources.
On the Report Data Sources dialog, chose the additional DataTable from the drop-down and clicked Add to Report. (I also renamed the new data source to just be the name of the additional data table; VS had created some gigantic long name based on the full namesspace.) OK to close the dialog.
On the designer for the form that contains my ReportViewer control, clicked the ReportViewer's smart tag (the little arrow in the top right corner of the control) and then selected Rebind Data Sources. This made a second BindingSource appear at the bottom of the Designer surface.
Clicked the ReportViewer's smart tag again and this time chose "Choose Data Sources" to confirm that the ReportViewer now had two data sources, each bound to one of BindingSource instances now on the form.
Revised the my form's OnLoad code to load rows into the second DataTable.
Went back to the RDLC file, added a new table and set the detail cells to fields in the second DataTable -- and it worked!
Hopefully this will save someone else a couple hours someday.
Figured out a way to use it in Visual Studio 2010.
Click on View > ReportData and when the report data is seen , click on Datasources and then click on add. DO this as many times as the number of datasets needed.
Now in the smart tags of the reportviewer, click on choose datasources, this will show each of the datasets. To associate the datasets with a binding source, you will have to click on Project and then further click till you get the appropriate class, this will cause the binding sources to be created.
This work around is very useful if you have multiple tablixes and you have to associate a binding source to them within the same report when the report is displayed on the report viewer

I'm modifying an SSRS report inside a Visual Studio project. The report is based on a view in SQL Server that I've modified. The DataSet properties refuses to pick up the new columns in the view without manually editing the XML .rsd file. Searching through these posts and on other sites going back as much as 10 years, there seems to be a "Refresh Fields" solution on the DataSet properties but my DataSet Properties dialog has no such button. I don't want to delete the data set and lose all the report formatting that is already done. There has to be a way to update the data set with new fields.
I am currently working in a RDLC report-generating application, and one of the reports is bound to a DataTable in my DataSet, which has multiple FillBy methods, which are needed depending on some criteria the user has already chosen. My problem is, one of the FillBy methods is generating additional columns that I need in my report, but they don't appear through the available columns to populate controls in the report. I can only choose between the columns available from the default FillBy method of the DataTable.
Is there any way of choosing which FillBy method is used in the DataSet when I want to set the source of my report's controls? I would like not to change the default FillBy method since it is already needed in other parts of my application.
P.S. If there is any code needed, table structure etc just tell me and I will reply as soon as possible. Also, either VB.NET or C# is accepted, since I can easily translate between these two.
Scenario:
I have an RDLC file - TestReport.rdlc
I have a form - Form1.cs
I have a ReportViewer - rptViewer
My datasource for the report will be an XML file or a datatable defined at run time (in button click event). Now when I am in design mode for the report how do I add the DataSource or DataSet to the report so I can "add" the columns/fields into the report?
Right now in the report when I click New -> DataSet I am asked to pick from Database, Service, Object or SharePoint but I want to use an object which exists in memory.
I am using VS2012.
Thanks,
Andrew
In case of XML, you have to create the schema for it and then add it to the report in the design view.
A little example is exaplained in this blog (it's old but still good to understand what you have to do).
If also the XML's schema is dynamic, the only solution I came out is about to create one paramater for each node/attribute of your XML and build one or more .rdlc files for every type of XML
I have little to no experience in using Datasets and Crystal Reports so please don't bash me if the answer is really obvious, I didn't manage to find the answer on-line.
I have a C# Winforms application, containing a Crystal Report that takes its data from a DataSet. I populate the DataSet dynamically from inside the application.
In the past, if I added another column to the DataSet, I could right click the DataSet in the Crystal Report and click "Verify Database" to make the new columns available in the Report.
Now, if I do this the following window pops up:
There is no item available in the Class Name combobox, and if I check the checkbox, another combobox appears which is also empty.
Please note that I populate the DataSet from inside the program, so there is no connection.
How can I update the DataSet in the Crystal Reports, so that the new columns become available?
Thank you.
P.S.: I have tried the following solution but it didn't work: Update DataSet Schema On Crystal Reports for VS2008 because I am presented with the same window as above.
Also, this is what I see, might be useful:
Edit1: The fields appear in the Data Sources but do not appear in the Field Explorer.
I already have some Formula Fields that have the same name as the newly added Columns but removing them didn't help either.
I finally managed to solve it by myself. There are three things I did and I'm not quite sure which one did the trick since I can't seem to manage to recreate the problem.
I renamed the Formula Fields that had the same name as the DataTable columns I added.
I clicked the " ... " box and reselected the same file.
I added the Internal Connection ID {294de39c-3e3c-4748-9138-53d4be2a74a6} in the Class Name textbox.
The first two probably didn't help since they didn't work before. It did work when I added the string so that's probably the solution, but this didn't work the first time either.
Hopefully my wasted hours would save someone's time.
This is my solution. Here is the steps:
Create New DataSet and drag the table from SQL Server ObjectExplorer
Right click on Database Fields
Choose Datasource Location
Click on the table on new DataSet created on step 1
Click Update
Hope it can help
We are using Crystal Reports XI R3 for our reporting purposes. We have created typed dataset which act as the datasource for the reports.
I am facing an issue including a bar chart along with the grid on one of the reports. The chart gets embedded into the header section by default and the grid is generated out of the details section.
If I design the report without the chart, it all works fine. If I supply 8 rows of data, it publishes 8 rows in the report too. But if I include a chart on the same report, the data in the details section gets multiplied, and I get 64 rows or something with the same datasource.
This should be a pretty straight forward functionality, but it doesn't seem to be working for me. I tried include a sub-report and have the details section in the sub-report and it works fine. But, I can't go with this approach either as this report in itself would be included to another as a sub-report and we cant have nested sub-reports in Crystal.
Please help me with some pointers on what could be going wrong ?
Edit: On further investigation, it looks like a problem with having two different tables to populate the chart and the grid. If I use a single table for both, it works fine.
Attaching screenshot on #Kalyan's request:
The issue indeed was with using multiple unrelated tables for a single report. Crystal Reports by default doesn't allow using multiple tables, unless they are linked in someway. If you dont specify a link, it tries to apply a link on its own and runs a join while publishing the report.
Due to this join, the data was getting repeated for me.
To resolve the issue, I created a group on the primary key of the table corresponding to the grid, and used the group to generate the grid and suppressed the details section. Problem resolved.
