Is it possible to conditionally hide (or show) columns when exporting a report to CSV?

We've noticed that our reports are including subtotals as a column with the value repeated for each row in the same group.  

I figured I could bind the visibility of the textbox to some value that indicates the rendering type (CSV, or other), but I can't find anything that indicates how the report is being rendered.

I'm using Reports 2017 R2

hi team,

we created a parameter in telerik report designer by providing option as multi selected value and in the preview mode we can see multiselected checkbox drop down appeared. But when we show .trdp file in asp.net telerik report viewer, same control is coming like multi selection list box.but we want multi selected checkbox drop down , how to achieve this? this urgent please respond.

We have been working with Telerik for around six months now. Everything has been functioning fine; however, it seems recently we are experiencing problems with the Cache eating up a few GBs on our virtual server. This leads to us not being able to load reports unless we login remotely and delete the Temp folder for the reporting. We are looking for a long term solution. We are working on increasing space on our server; however, we would like to be able to somehow limit the cache size (which would hopefully make things a little more predictable). I've also thought about tying into the database for caching; however, I'm hesitant to do that because I don't know how much space it would take up.

I want to make a table like blow:

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

category   |  Name |   Amount | Total |

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

                 |paper   |   5           |          |

AAAA       | Pen     |   10         |    20  |

                 |XXX     |   5           |          |

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

What can I do?

Hello,

I have created a Telerik Reporting REST service in order to render "telerik reports" on my Web Application in HTML 5 view. I am currently using the following code on my Web Application page "Report.aspx" to consume the service.

 <script type="text/javascript">
       
        $("#reportViewer1")
            .telerik_ReportViewer({
                serviceUrl: "http://localhost:62355/api/reports/",
                templateUrl: '/ReportViewer/templates/telerikReportViewerTemplate.html',
                reportSource: {
                    report: "VB.ReportLibrary.ReportCatalog, VB.ReportLibrary",
                    parameters: {
                    }
                },

                viewMode: "ViewModes.INTERACTIVE",
                scaleMode: "ScaleModes.SPECIFIC",
                scale: "1.0",
                PersistSession: "true"

            });
       
    </script>

When I open "Report.aspx" it throws an error "Client with ID '[object Object]' not found. Expired" on locally running Service App (See attached image "ServiceError.jpg"). At the same time client side(Web App page Report.aspx) shows an alert message "Gone" (See Image 410_Gone.jpg). ReportsController.vb code is as follows:

Imports Telerik.Reporting.Cache.Interfaces
Imports Telerik.Reporting.Services.Engine
Imports Telerik.Reporting.Services.WebApi
Imports System.IO
Imports System.Web.Http.Cors

'The class name determines the service URL.
'ReportsController class name defines /api/report/ service URL.

<EnableCors("http://localhost:53274", "*", "*")>
Public Class ReportsController
    Inherits ReportsControllerBase

    Shared configurationInstance As Telerik.Reporting.Services.ReportServiceConfiguration

    Shared Sub New()
        'This is the folder that contains the trdx or trdp report definitions
        'In this case this is the Reports folder
        Dim appPath = HttpContext.Current.Server.MapPath("~/")
        Dim reportsPath = Path.Combine(appPath, "Reports")

        'Add resolver for trdx report definitions,
        'then add resolver for class report definitions as fallback resolver;
        'finally create the resolver and use it in the ReportServiceConfiguration instance.
        Dim resolver = New ReportFileResolver(reportsPath) _
                       .AddFallbackResolver(New ReportTypeResolver())

        'Setup the ReportServiceConfiguration
        Dim reportServiceConfiguration As New Telerik.Reporting.Services.ReportServiceConfiguration()
        reportServiceConfiguration.HostAppId = "reportViewer1"
        reportServiceConfiguration.ReportResolver = resolver
        reportServiceConfiguration.Storage = New Telerik.Reporting.Cache.File.FileStorage()
        reportServiceConfiguration.ReportSharingTimeout = 0
        reportServiceConfiguration.ClientSessionTimeout = 9999
        configurationInstance = reportServiceConfiguration
    End Sub

    Public Sub New()
        'Initialize the service configuration

        Me.ReportServiceConfiguration = configurationInstance
    End Sub

    Protected Overrides Function CreateCache() As ICache
        Return Telerik.Reporting.Services.Engine.CacheFactory.CreateFileCache()

    End Function

End Class

Can you please provide a solution regarding same. My end goal is to render telerik report on web form page using html 5 report viewer (See expected_result.jpg).

One of our client when to repeat a table on every page of the report. My idea was to use the page header to achieve but I discover that the page header doesn't accept any data-bound items on it.

So my question, does it exist a way to repeat a data-bound item (texbox, table) on every page of the report?

Hi,

I am using Telerik Reporting Q2 2015 with ASP.net MVC ReportViewer (UI for ASP.net MVC). In this I am not able to disable cache at server side, can you please share the option to disable cache from both client & server side.

 This will help me to pull the report every time from database & share the update data in the report.

-thank you
