Hi there,

after updating our reporting service to 10.2.16.914 we found this issue:

if using TextFields (like txtPeriodHeader) and set Value in a NeedDataSource event, they are empty.

After resetting to 9.2.16.1216 everything worked as expected.

This works in 9.2.16.1216 as expected, in 10.2.16.914 we got empty fields.

Best regards

Manfred

Hi,

I need To print 2 headers respectively to there data  in a report.

    i.e.:       - print the first Header on every page until it's data section all printed

                 - then break the page and start the next page with the 2nd Header and keep going with the second Header until the end of the report.

I tried binding in the Header Section  and set  

"PrintOnEveryPage" to : PageExec( "DetailSection...and other Items", Count(Fields.TriedManyItemFromDataObject)>0)

but it is returning a 0 all the way. I checked your invoice example to understand the function specially the scope parameter and I see that you are using "lineTotalDataTextBox" as scope in you examples. Could you explain why you are choosing only this textBox ?

I will appreciate any help in Advance.

Thanks.

I must be missing something obvious but I am unable to create a 'simple' grouped table according to the following layout:

-------------------

| GROUP1

| -item1

| -item2

| GROUP2

| -item3

| -item4

-------------------

The datasource i am using is flat.( Item1 { Group ="GROUP1", Name = "item1"}) etc.

Is it even possible to do this with a single table? I've been going at it for about two hours now, i've seen all kinds of results, but not what i need :-)

Hi, I am using VB.NET web application with Telerik Reporting (standalone designer) where I am passing some parameters from VB.net code to the Telerik report, as shown below. 

ReportViewer1.ReportSource.Parameters.Add(New Telerik.Reporting.Parameter("FromDate", dtpFromDate.SelectedDate))
ReportViewer1.ReportSource.Parameters.Add(New Telerik.Reporting.Parameter("ToDate", dtpToDate.SelectedDate))

This works fine for a single-value parameter, however, how can I pass on a multivalue parameter from VB.net to the Report. For instance, I am using a radCheckBoxList where the user can select more than one selection. How to pass the radCheckBoxList selected items/values to the multivalued parameter.

Thanks in advance,

Hi,

I want to set the detail height of the section in Telerik Report ..........

For Example :-  In detail section it must accomodate 10 records in this section, if the report contain 1 record ,9 empty records will be inserted in the detail section... 

using sqlDataSource with parametrized store procedure,

Is

it possible to show a "no data exists" message if the query returns no data?

Having a problem with one of my reports, it either gets blank or shows the same data regardless of which value I set the (using only one parameter) report parameter to.

I have discovered that if I set the parameter to a value in the "Configure data source parameters" it will allways show a report with data based on that value. Even if I set another parameter by source code.

If I don't set the value of the parameter in "Configure data source parameters" the report shows up blank, regardless of which value I put into it at designtime (Preview) or runtime (by code).

It's like the value set by designtime or at runtime gets overrided by the value in "Configure data source parameters". If I leave value in "Configure data source parameters" blank the report will be blank.

I've checked all the things mentioned in "http://www.telerik.com/support/kb/reporting/details/problem-telerik-reporting-renders-blank-pages". I've tried re-create the data source. 

Hi there,

I have deployed a Telerik Report (v9.1.15.731) on a machine, and the report itself works great. But when I try to “Export” the report, or click the "Print" icon on it, after the “Save As” window appears and I save, the file doesn't get saved.

It eventually does get saved, but once in every 10-15 tries. It is random. And this issue occurs only in reporting.

I have checked the EventViewer Log and found that the following exception appeared every time this issue was faced. Here is the full log:

Currently doing an evaluation of Telerik reporting for use in an ASP.NET development.

Really struggling to see how to access the subreport data from the main report. All I want to do is display some totals from the subreports onto the main report. Really easy in SSRS or even Access, can't see a straightforward way in Telerik. Please help.

I have .trdp report designed in the Telerik Report Designer and displayed with html5 report viewer with REST service.

Initially the report is loading only the group headers and when you expand one the whole report is reloading to get the rows in the group (same for collapsing).

Is it possible the report to load all the data at start, not only group headers, and the expand/collapse to only show/hide the rows html?
