Hello.

I am trying to dynamically create a report, without any designer, just c# code. I am using instance report source with a report document, to which i add items on the fly, based on a custom report definition containing the user required report format (columns, rows, sorting, etc). 

No matter what i do, the final report gets rendered on pdf with an empty page. The problem is that with the same report items, i am getting results when using visual studio designer. I am referring to teleric report examples in C# (ListBoundReport). I have modified the designers class report items to just include a singe section with a table having one column and row. The output in the designer preview is an empty table having only visible borders.

I have copied the report items from the above example in my reporting library implementation. The difference is that the items are constructed in a custom builder class instead of the report item constructor as in your example. The outcome is a pdf with no visible table. 

I can post the builder class that creates the report items, but it has a lot of custom information that will get you confused. Instead, i will post the modified code from the designer file in your example. I can attach my builder class code, as well, if needed.

Please let me know what i am doing wrong because i have created a whole infrastructure in the idea of creating on the fly reports based on some user configuration.

Hi All,

I have a date field in my sql query.

I want to create a report in which i want to show Current year(2016) and previous year(2015) data only.In the same way i want to show current month and previous month data.

 

So can someone tell me how i can convert my date to current year and the previous year or current nonth and previous year.

 

I am using Standalone report designer.

Hi. I try to select report engine for my application and play with Telerik reporting. Almost all clear and working as expected.
One question. In what way I can get selected page size, orientation etc in reportViewer?
After call ShowPageSetupDialog for example...

New to Reporting.  Trying to evaluate for our product launch.  

Context:

1. Visual Studio 2017

2. WPF App

3. Data is "contained in" our library

4. I would like to use the designer by editing a trdp file for setting up the report

5. Configuration is AnyCPU

No matter how I modify the app.config file, I can't get any object entities to show up anywhere in the designer.  what am I doing to prevent that?  Examples of this anywhere would be helpful.  Couldn't find anything using Google.

Hi,

 

I have a main report and 3 sub reports. I referred to the telerik documentation and the forum. I have a objectdatasource in the main report and the sub report relies on the parent datasource --> =MainReport.objectDataSource1. I have also set field value to =MainReport.objectDataSource1.FieldName in the subreport.

The report loads successfully but there is no data. It's very frustrating and I have a spent of lot of time trying to resolve the issue.

I will appreciate it, if you can please assist me with this. 

 

Thanks,

Ashith.

I've looked through other posts, and I think I'm doing this correctly...but I must be missing something. I have a report that I created within VS2015 using 2018 R2. I don't want to show the report in a viewer. When I click a button, I have it rendering straight to a PDF. I only want the report to show info for the record I'm on in the application, so I created a parameter. When I pass the parameter, it doesn't use what I'm passing. Maybe I'm not understanding parameters. I want the report to pull info using the following SQL: select id, employee_id, employ_badge from employee where id = @id. (this is an example of what I want). I've included the code below. What am I missing? Am I loading the report wrong? Have I misunderstood parameters? Also, how do I set the datasource in the code behind? I've looked at the example that attached with a similar post and it looks like what I have.

protected void btnPrint_Click(object sender, EventArgs e)
{
Telerik.Reporting.Processing.ReportProcessor reportProcessor =
new Telerik.Reporting.Processing.ReportProcessor();
// set any deviceInfo settings if necessary
System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();
Telerik.Reporting.TypeReportSource typeReportSource = new Telerik.Reporting.TypeReportSource();
// reportName is the Assembly Qualified Name of the report
typeReportSource.TypeName = typeof(Report1).AssemblyQualifiedName;
int RowID = Convert.ToInt32(ViewState["FORMROWID"]);
typeReportSource.Parameters.Add(new Telerik.Reporting.Parameter("id", RowID));

Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", typeReportSource, deviceInfo);
string fileName = result.DocumentName + "." + result.Extension;
string path = System.IO.Path.GetTempPath();
string filePath = System.IO.Path.Combine(path, fileName);
using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
{
fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
}
WebClient User = new WebClient();
Byte[] FileBuffer = User.DownloadData(filePath);
if (FileBuffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", FileBuffer.Length.ToString());
Response.BinaryWrite(FileBuffer);
}
}

Hi,

I need to build a report which has its DataSource a List<Object1>
Object1 has a List<Object2>
Object2 has a List<Object3>

All objects have a property Name(and some other details)

Report should show like:

Object1.Name
* Object2.Name
** Object3.Name
** Object3.Name
* Object2.Name
** Object3.Name
** Object3.Name

Object1.Name
* Object2.Name
... and so on.

I`ve created a list1 which has the datasource - List<Object1>, but after this I got stuck, I can't find a way to set the datasource for the next list which would need to show Object2 list, and after that, Object3 list. How can I achieve this without building the controls from code?

I must mention i`m new in working with telerik, in case this was not found out yet.

Thanks in advance.

Hello,

I have a problem with the group footer section. My objective is to stick it to the last printed row of a table in the detail section.

I have it configured to PrintAtBottom = false

On the page i have only 2 groups and in the detail i have a table. 

When the table row is too height and it doen't fit in that page, the group footer section is printed always on bottom of the page, and i do not want that, i want it to be printed right below the last row of that table in that page.

I already play it around with the keeptogether and it didn't work.

Can somebody help me?
Thanks,
Nuno

I'm trying to evaluate some fields inside a table in my report, however I see that the table has its own datasource property, I want to set the datasource property to be the same as the report's datasource, how can I do so? thanks!
