I use sub report in the footer of parent report.
There is a field of Document Type.
i want that Sub Report Visibility is false when Document Type = "DELIVERY ORDER".
I give the condition

Expression                               Operator                      Value
=Field.DocumentType                   =                      ="DELIVERY ORDER"

But this is not working it is show that report.
Help me.

The Export options are missing from the Report Viewer - I'm using the HTML5 Report Viewer.  The icon is visible but clicking it does nothing. 

I can successfully call api/reports/formats and see the available formats in the returned json
I have references to DocumentFormat.OpenXML and Telerik.Reporting.OpenXmlRendering

According to the docs this is enabled by default, so what am I missing?

Hello,

I am trying to create Telerik reporting table programmatically , facing an issue with Telerik.reporting.table where my datatable rows are not getting rendered. Report is showing up only columns not rows. For more info, please find attached images for datatable and Telerik.reporting.table.

Here is code snippet my using


Please advise how to resolve this issue? 

The report I'm building is using a CustomReportResolver and has System, ReportName and Footer parameters that I am adding to the report at runtime.  Whenever the user selects new criteria for the report (handled separately) and then refreshes the ReportViewer in the MVC page (razor), I then rebuild the report from scratch - re-adding the parameters with respective values, along side my custom data object source.  The problem is with displaying the footer text parameter that contains a big long string describing the criteria that the user has selected.  However, even though I can see, using breakpoints, that the report being built contains the updated footer text, when the report refreshes (html5 / web/api) the footer parameter still contains the text from the first time it was built.  Why are the parameters being cached even though its a brand new Telerik.Report object? and how can I stop this so it will show the latest text that I've added?

Here's my current scenario. I have 100+ records, grouped by one of their column values. Each detail record has a "Days Elapsed" integer value. I am trying to determine the value of Days Elapsed at the 90th percentile for each group. I can find what record I need, ie a group has 77 records, the record at the 90th percentile is the 69th. So what I want is to display the Days Elapsed value for the 69th record within that group.

Is there any way to do this?

I am using a trial version of Telerik Reporting and I can't get past a connection string issue. I'm using the HTML5 Report Viewer and running it locally.

I have created a simple report in VS2012 with a SqlDataSource that uses the default connectionstring:


In my app.config I have the connection defined:

I can preview the report in Visual Studio, but when I view it through the report viewer I get the error:


Telerik Reporting is very new to me and I seem to be going round in
circles trying to find the solution. Can anyone shed any light on this?

Hi all,

Is there an easy way to add a trendline (trend line) to a Telerik Scatter Chart? This is something management is doing in Excel, and they want to see it on the Telerik reports too. See attached. 

Right now I'm going down the path of calculating my own line from the data to add to the chart. Is this the easiest way?

Thank you

Hi, 

When the right set of data points present themselves, the smooth curve line will go outside the boundaries of the graph. (see attached image)

Any best practices to help prevent this?

Thank you
