Merging more than one rdlc into single reportviewer control - c#

I want to merge 2 .rdlc files (with C#) into a single .rdlc so that it prints in a single file in reportviewer control.
This is what I'm trying:
this.reportViewer1.LocalReport.DataSources.Clear();
reportViewer1.LocalReport.ReportPath = "model1.rdlc";
reportViewer1.LocalReport.ReportPath = "model2.rdlc";
this.reportViewer1.LocalReport.DataSources.Add(datasource);
this.reportViewer1.RefreshReport();
but it's only showing me the second report (model2.rdlc)


Reportviewer show's just one report file at time
because you overwrite the report path at the second line
it behaves like that (showing the last report)
You have some options:
1- Using subreport inside the first report and setting the supreport parameter as report 2.
2- Using multiple data sourses for one report and merge the two reports in the report.
3- Using the page brake option to split your report to multiple pages but it has some limitation because of it cannot work at any area unless it has a container in the report like (table - rectangle - matrix).

Subreport is getting truncated on Active Report

When I am running the report and if subreport has more than 1-page data then it is showing data on the first page only and truncate all remaining data. I have used BandedList for the report.
PFA
I have 20 more Fields which are not showing on next page.
UPDATE (12/07/2017)
I am using RDL report. I have attached screen shot
CompletedOpsSubReportPortrait.rdlx is my subreport.

I need to change source in rdlc report

I made an rdlc report before and now I increased two columns in database table. These two columns are not showing in report, what should I do?

In the Report Data Window, refresh the Dataset. new fields will be available in the dataset and you may need to add new fields to your report accordingly

RDLC Dynamically Add multiple child report (rdlc) to Parent report (rdlc) from codebehind and show it on reportviewer

I am new to RDLC and the report viewer so I am not sure if this is possible.
I have a parent report and based on user selection I want to add all the sub report to the parent report and display it to user in report viewer.
Example: We have following report.
1) Master Report A.rdlc
2) Report B.rdlc
3) Report C.rdlc
4) Report D.rdlc
5) Report E.rdlc
Sample scenario: If the user selects Master report and select 2 reports, Report E and report C.
So the output of the report should include selected report and it should also maintain the order in which the report is display in report viewer.
Master Report A
Report E
Report C
I tried using sub-report it works good for me only if I know the order and no of the sub - report at design time, but how to do it dynamically at run time on user selection,I don't know how to handle order and how many reports will be added at run-time.

To control which reports are being displayed and in which order, you could introduce additional dataset which would "drive" report order and set visibility properties of the reports, for your example it would be something like this:
<?xml version="1.0" encoding="utf-8"?>
<reportWrapper>
<reportSetting order="0" type="A" visibility="false"/>
<reportSetting order="0" type="B" visibility="false"/>
<reportSetting order="2" type="C" visibility="true"/>
<reportSetting order="0" type="D" visibility="false"/>
<reportSetting order="1" type="E" visibility="true"/>
</reportWrapper>
Then, add new dataset as datasource to your Master report, add Tablix to the report body, assign new dataset as datasource to this tablix (set order by column "order"). Then, you can place your subreports into that Tablix in the detail row and set visibility on each of them separately according to their type and visibility column of new dataset. For example, for report A it would be - hidden when:
= Fields!type <> "A" OR Fields!visibility <> "true"

Generate RDLC Report with two columns

I need to build a report (.RDLC in visual studio 2012) that contais a long text in two columns by page.
I can't just add a new column in the report, because the content above of this long text will be dynamically, so, this control (to fill the text in the second column) must be dynamically too.
Also, i need to add others parts of the report after the text ends.
Somebody knows how to do this?

C# create report programmatically

I want to create a report, using either Crystal reports or RDLC, doesn't really matter which. I can get all the data sources together as a series of dynamically generated textboxes etc, but how do I add that to a report?
Eg I want customer name and all of their ordered items in a report. Now I can get all of the information in an array... how would I then place that into a Crystal Report?
Any good introductions that cover non-wizards for Crystal Reports would be amazing.

Every datasource of your report has a name (menu report->datasources, It can be not exact because my vs is not in English).
Supose that one of your datasources name is prj_folder_classSample, and classSample is a class of your project. Then you need to add a List to the report.
Let's do it.
List<classSanple> lst = new List<classSample>
lst.Add(...) //Add various instances of classSample
BindingSource thisIsABindingSource = new BindingSource();
thisIsABindingSource.DataSource = lst;
reportDataSource rds = new ReportDataSource("prj_folder_classSample", thisIsABindingSource);
ReportViewer1.ProcessingMode = ProcessingMode.Local;
ReportViewer1.LocalReport.EnableExternalImages = true;
ReportViewer1.LocalReport.ReportEmbeddedResource = "YourProject.Folder.reportName.rdlc";
ReportViewer1.LocalReport.DataSources.Add(rds)
I do it in this way. Hope It helps you.

Look at this link http://msdn.microsoft.com/en-us/library/cc281022.aspx#RDCE if you want to dynamically change your report. This extension is called just before the report is rendered. Microsoft has created a RDL Object Model. With this one you can customize your whole report. But maybe you don't need this extension. Just try first your stuff in the Report Designer.
