Not supported to value: /xl/worksheets/sheet1.xml'  I have 2 examples one works fine and other is not. can you please guide us why one file is failing and other is not?

Hello, 

I am trying to get the total rows from a table in my detail section that is bound to a secondary data source, that is, not the data source of the report.

The report is bound to a header data source that contains client information, and has one row.  The table in the detail section is bound to a second data source that contains all that client's products.

I would like to put a footer textbox with the total products from the table's total rows.

I'm trying the query builder for the first time, trying to create a very simple query. IDItemMaster and ItemMasterID are the keys. I click on add new relationship but nothing pops up and when I click on edit on the blank relationship the relationship tab closes. 

We converted the .rpt file to .trdp file using Telerik Standalone Report Wizard. We have a header and the details consist of many sub reports. we need to display the values in the sub reports getting the data from different select queries. We are not sure about specifying the data source for each sub report. 

Need help on the below items

1) How to set the data source to main report? how to set the separate data source to each sub report?

2) When we tried to set the data source for one of the sub report, we are able to only invoke the fields of that data source in another sub report. But we are able to create a separate data source in common. Can you help us with this?

Have been making some changes and updates to an existing Blazor web assembly project, and I have most things fixed/resolved regarding the reporting.   However, I get the following when trying to actually display a report:

"The version of the Report Viewer '18.1.24.606' does not match the version of the Reporting REST Service '18.1.24.709'. Please make sure both are running same version"

The dependencies in the projects all show Telerik Packages with version 18.1.24.709... so clearly I am overlooking something.  Clean & Rebuild does not help -- what am I overlooking.

Thanks.

Thanks in advance.

Trying to integrate the native blazor report view into my we app, but running into all kinds of issues...I have the Rest Api installed, and the reportviewer.  I keep getting      

 Failed to load resource: the server responded with a status of 404 (Not Found)
telerik-report-viewer:1 Uncaught (in promise) Report '%2FReports%2FSampleReport.trdp' cannot be resolved. 

 or         

Failed to load resource: net::ERR_CONNECTION_REFUSED
telerik-report-viewer:1 Uncaught (in promise) Invalid ClientId  

The documentation is horrible and I can't get a response from support...hope somebody has some experience with this.

Also, .net 8 web app in auto mode...

I have a program to Order a widget.  When they order widgets, they are allowed to pick and choose options for those widgets.

The options are stored as individual records in a SQL table like this:

ProductID      OptionID
     5                     6
     5                      13
     5                      101

So, I want my report to show the total list of options as checkboxes, when that value is present in the datasource.  Options not selected should be unselected checkboxes.

I'm guessing this will be a subreport, passing in my ProductID.  The result would be a datasource with three records.  How do i associate these records to trigger checkboxes on my report?

Thanks

I would like to avoid writing my SQL to include record fields for every possible value as the options will change and I'd have to re-write the SQL every time.

This is VERY URGENT: a business database migration from SQL Server to PostgreSQL, due to happen this weekend, is dependant on it.  I'll ask the question in 2 parts:

1. We have a SQL Server database called TelerikReportingCache, containing tables tr_AppLock, tr_Object, tr_Set and tr_String, which is used by Telerik Reporting. I have been told that this database cannot exist on a PostgreSQL server. Can you confirm that this is correct, please?

2. We have been told to use a file for the cache instead of a database. However, we have many users, and the file gets locked, causing an error message in reports - see image in attached file. If we cannot use a file as a cache, then what other alternatives do we have?

Error Message Text: Error creating report instance (Report = 'ConnectReports. Finance.CustomerInvoiceSummary, ConnectReports"). An error has occurred. The process cannot access the file '\\172.21.23.75\Telerik ReportingCache\ConnectReports 16.0.22.225\Is\A\value.dat' because it is being used by another process.

My titled should be "Can I DECRYPT my connection string" - however, I cannot modify the title above.

In my .Net 8 appsettings.json config, I have these two connection strings:

"ConnectionStrings": {
  "MyReports.Properties.Settings.dev": "Data Source=Eng-Server;Initial Catalog=devsvr;Persist Security Info=True;User ID=myID;Password=myPass",
  "Encrypted.Properties.Settings.devEncr": "jjwerjwerjwerjwerjwerjwerjwejwerjwer=="
},

The first conn string works fine when Telerik Reporting resolves the DataSource connections at runtime, however if I try to use the Encrypted string - it does NOT work.

Can you point me to some documentation on how I can get it to work with encrypted connection strings ?

I know that the Report Config object is exposed at the ReportsController level, for example:

public class ReportsController : ReportsControllerBase
{

    public ReportsController(IReportServiceConfiguration reportServiceConfiguration, IConfiguration configuration)
        : base(reportServiceConfiguration)
    {
    }

}

however where would I decrypt my string ?

By the way, I also have a ClassLibrary with some custom code. I use that DLL in the standalone report designer to hook up a DataSourceObject for some custom methods I need to call. Would I possibly hook into the connect string, and decrypt it here ?

Thanks,

Bob
