I have a multi-value parameter, @CountryID, that can also be set to null.  

I have a sql database query that uses this parameter like such:

"select * from Countries where CountryID is null or CountryID in (@CountryID)

Running the report, everything works as expected when I set the parameter value to NULL or to a single value.  However, if I set it equal to two or more values I get the following error:

An error has occurred while processing Table 'crosstab1': An expression of non-boolean type specified in a context where a condition is expected, near ','.

What am I missing?  How do I configure the parameter and/or adjust the query so that it works with NULL, single values and multiple values?

Thanks!

Hi，

I want to pass parameters to the report so that the font size in the Style of the report can be set according to the content of the parameters. For example, if the parameter ReportFontSize=9, then the font size of the content in the Label control and Table control in the report will be 9pt. Is there a way to achieve this currently?

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...
