Hello, Im new at this, I am watching how the Telerik Reporting and I have the following questions:

We need a developer to download and install the Telerik Reporting Trial solution to see if it addresses our needs.  We need to specifically look at the following feature evaluation:

1. What type of data source specifications are supported?  Can we specify a data source at run-time?  This may be necessary to properly implement our multi-tenant reporting solution.
2. Can we build a chart/graph only report that would work in our dashboard.  These would have a different data source than the standard reports.
3. Can parameters be passed via URL to a report?
4. How is the reporting solution installed?  Will it require a dedicated server?
5. Can we foresee any security issues?  Will we have to expose the reporting or transactional database to the web tier?
6. How effective is it's support for MySQL?
7. How do we implement hidden parameters in a report?  We need to be able to implement a CustomerID parameter that is programatically set which cannot be intercepted or modified by the end user.  This is required for multi-tenant security.
8. Need to determine if we need to purchase the source code.
9. Can we programatically invoke an existing report, intercept the output and send it to a mail server as an attachment to an email?  Basically, this would be a roll-your-own report scheduler.
10. How are reports persisted (file system, compiled code, etc.)?  How difficult to add new reports to the system?

I hope you can help me.
Thank you!

Hello everybody...

I have created a report and i need to display images. This images are in db. On the design of my report I put this code:

this.pictureBox3.Value = "=Fields.Front";

When I run my report from a Windows Form , I get the "Parameter is not valid" exception.

Please, if someone has an idea, tell me what must I do...
Thanks...

Hello,

When I use expression to bound a value to a textbox I would have something like this:
this.textBox2.Value = "=Fields.JobID";
Now, how can I access this value in the code.
I tried:
string str = textbox2.value.ToString();
but I got "=Fields.JobID" which I expected to get an integer number.
I also tried string str = "=Fields.JobID" and it didn't work either.
How can I get this fields value in the code.

Many thanks

Hello,

When exporting a report to excel, I always get the following error:

"Trying to subtract from Unit.Empty!"

After some tests, I discovered that when I copy/paste all the objects of the report one by one or a group of objects to a new report, everithing works fine. But, when I select a specific area of the report (repor theader, report details, etc.) and do a copy/paste, then the error appears.

Can you tell me what seems to be the problem? This behavior is very strange and I think that its not a good idea do a copy/paste everytime this error appears in a report.

Thanks for your support.

I have a Parameter that is a list.  Is there a way to automatically refresh the report when the parameter has chaned?

Hi,

I am a bit confused in the different previews when designing the reports. Why is it that what I see in the Preview is a bit different from the HTML preview?

For instance, I would like to have a textbox with a few line of information.

"I want to go there:             Washington"
In this case, in the preview is working fine but when in html preview, the tab in between is gone and I  am not sure if when print how it will show. I am assuming that when print, it follows what is shown in the preview tab and not the html preview tab. Is this right?

"I want to <b>go</b> there: Washington"
In this case, I want the 'go' to be bold and the other words not. I have to put the <b> tag so that in the html preview it is shown bold but in the preview tab it shows the tag. When I print it out it also show the <b> tag and the word 'go' is not bold.

Basically I am facing a lot of confusion as what I will see in my application and what I print out is different. How can I go about it that what I see is what I will print out? And lastly is that whenever I made changes to the report design, I cannot preview the latest changes until I do an iis reset and close open Visual Studio then only I can see the latest changes in the preview and application.

Lastly is that lets say I design a report in which will span a few pages. In the preview tab shows how many pages I will have. However, in the html preview and application, it shows the report as 1 page with no page break indication or how many pages. In the report viewer in the application shows only 1 page. But when I print out, it will show like maybe 2 pages or 3 pages and when print of course 2 pages or 3 pages.

So I have problem in the designing the report, showing in the preview tab, html preview tab and application report viewer shows different things and also that I cannot see the latest changes made to the report without reseting iis and close open visual studio to view the latest changes.

Thanks.

Hi,
 I have a master report with 3 subreports and there is a bar chart on one of the subreports. In the bar chart report class, I have a databind fiunction, for testing, I am manually populate the data, but later on I need to pass a dataset into this function. 
public void DataBind(DataSet aDS)
{
           ChartSeries chartSeries = new ChartSeries();
            chartSeries.Name = "Sales";
            chartSeries.Type = ChartSeriesType.Bar;
            // add new items to the series,
            // passing a value and a label string
            chartSeries.AddItem(120, "Internet");
            chartSeries.AddItem(140, "Retail");
            chartSeries.AddItem(35, "Wholesale");
            chart1.Series.Add(chartSeries);
            
//bind DAtaSet

chart1.ChartTitle.TextBlock.Text =

"My Test Chart";

chart1.Report.DataSource = aDs;

chart1.Series.Clear();

ChartSeries s = new ChartSeries();

s.Type =

ChartSeriesType.Pie;

s.DataYColumn =

"Value";

s.DataLabelsColumn =

"Desc";

chart1.Series.Add(s);

 }

On the master report class I have a function that call the databind function, 
 public void SubReportChartDataBind(DataSet aDS)        
{            
             MyChartReport rpt = new MyChartreport();
             rpt.DataBind(aDS);
            subReport3.ReportSource = rpt;
 }

and this SubReportChartDataBind function called by the report viewer aspx page. 

DataSet oDS = GetDataSetForChart();

MyReportMaster rptMaster = new MyReportMaster();
rptMaster.SubReportChartDataBind(oDs);
this.ReportViewer1.Report =rptMaster;

But on the chart, ther is no data shown, the error is "there is no or empty series". Anybody can give me a hand?

Thanks in advance

Hi,

I would like to try the fantastic Reporting Control in a winform application.
Unfortunately I got an error on the first line of my application... Look at the code below.

The error is
Exception has been thrown by the target of an invocation
The type initializer of 'MyObj.OrdersData' threw an exception

In fact the OrdersData could not find (I think) the connection string in my app.config

What could I do ?

Partial

Public Class Report1
Inherits Telerik.Reporting.Report
Public Sub New()
    InitializeComponent()
    Dim Orders As MyObj.OrdersCollection = MyObj.OrdersFacade.GetAll
      ' me.datasource = Orders
End Sub
Public Sub main()
End Sub
End Class
