Hi all,

I have installed Telerik controls first and then installed Telerik reporting on win 7 64bit but only telerik report are not showing in visual studio 2008 and 2010 both.

Kindly let me know how to resolve this issue , I have to develop sample report and give the demo as my company is willing to purchase any RAD controls, I have proposed Telerik controls as I'm familiar with it.

Thanks

Leo

Reporting version 2019 R3 SP1 (13.2.19.1213)

In the Standalone Designer, with a .trdp file open, you can see the fields from the data source in the Data Explorer. For me, these come from a stored procedure.

If change the stored procedure to add/remove columns, then click the "Refresh" icon at the top of the Data Explorer, nothing happens; Data Explorer still shows the old items. Closing/re-opening the Reporting tool will fresh the Data Explorer list. You should not have to close/re-open. Isn't that what the "Refresh" button is for?

Hi,

I have been following https://docs.telerik.com/reporting/web-report-designer-setup-in-net-core to add the web report designer to an aspnetcore project both on .net core 2.1 and 3.1 and I am getting javascript errors because of these files:

<script src="..../js/telerikReportViewer"></script>

<script src="..../js/webReportDesigner"></script>

The article does not explain where are these references and how they work. And also why do you have to register services  in a different class instead of the ConfigureServices method of Startup.cs?

I'm trying to set things up for the first time in a .Net Core ASP 3.1 Application.

My ReportsController appears to be recognized properly (the constructor is called with the IReportServiceConfiguration) and the client attempts to call:

api/reports/resources/js/telerikReportViewer (with a ?_=<number> on the end)

But i'm getting this error:

"Message": "An error has occurred.","ExceptionMessage": "An item with the same key has already been added. Key: Cache-Control"

Full:

Hi,

I use a multi-value Parameter to select a subset of data in an IN clause.

On SQL Server if the User selects a lot/all of the possible values, this occasionally leads to the following error:

Too many parameters were provided in this RPC request. The maximum is 2100.

Since SQL Server does not support arrays as parameters, I assume the reporting engine does some magic to rewrite the parameters to

IN(@p1, @p2, @p3 ...)

Is there a way to workaround the problem, for example by using a temporary table with the parameter values?

Regards

Erwin

Is it possible to display server timezone in this format "DD-Mmm-YYYY hh:mm:ss timezone" in Telerik Reports

For Example -

Example 1: "13-May-2020 03:30:53 AM EST".
Example 2: "13-May-2020 12:30:53 AM PST".
Example 3: "13-May-2020 01:30:53 PM IST".
