Hello,

I have an existing report that consists of two pages and should have the same header on both pages, but different footers. How can I transfer the existing report to the report book without changing the code under which the report was saved? Or how can I add two different footers into one report?

Thank you for your reply.

When ever I rotate the textbox angle within (90,180,270), this work. 

I have  a problem dealing with angles like ( 315),  the text is always wrapped to the next line regardless of the size of the textbox and number of characters of the textbox value .  So for example, "Etzebeth Thomas" is shown as "Etze" first line and the rest disappear or get displayed within the second line and so forth. 

Look at the below picture

This looks like an old issue based on the below post.

Hello,

can I disable Expressions on a TextBox? I am using Telerik Reporting in a C# Project.

I have a TextBox in my Report that has its value set to a string in the Reports code. If the string starts with an "=", the entire string is treated as an expression and is calculated in the rendered Report. Is there a way to display the raw text in the Report TextBox with a "=" at the start and without any calculations applied?

Addind Quotation marks to the string in C# code does not seem to work, as it now adds these Quotation marks to the rendered TextBox.

Thanks.

 I am using Telerik report in my c# project using their REST service, I am using the R1 2017 version, the parameters are all loading and their respective data from the database is also loading but I am getting this error when I click on preview,

When I analyzed the Telerik DLL with the error it meant that the parameters values list is null, but it can't be because I checked the network log, all the parameters are being passed to the REST API. This is the payload I'm sending

{"report":"Activity/Registered Users Report.trdp/VisionReport","parameterValues":{"CPR":"353464654","EMAIL":"","MOBILE":"","FromDate":"2023-12-31T00:00:00.000Z","ToDate":"2024-01-01T00:00:00.000Z","ChannelId":["006","002","005"]}}

to this telerik URL :

https://localhost:44302/api/reports/clients/aaf42228070/instances

When I run the same code and report in my local environment it runs properly. Still, when I deploy the code to the server, I receive this error, I ran the report on Telerik Designer on the server, there also it loads fine, it only causes issues when I am loading it in the browser on the server. Following is the complete error I'm receiving from Telerik.

Hi,

We are implementing Telerik Reporting in our ASP.NET hosted Blazor WASM application (using .NET 6).
So far we based our implementation on the following sample: https://github.com/telerik/reporting-samples/tree/master/BlazorViewerAndDesignerExample.

We are looking for a way to pass the User from HttpContext of the ReportsController (for viewer and designer controller) to the WebService datasource, so we can authorize the datasource request based on the user ClaimsPrincipal. The webservice datasource is an api controller that is part of the same ASP.NET project.

Is this possible?

Alternatively, if we could pass a certain cookie from the request to the ReportsController to the webservice datasource request, we could make the authorization work with that.

Kind regards,

Lennert

Hi Team,

I've dabbled with this a little bit, but I've got a parameter in a report that's set to take an array of images. I've inserted a list and set the datasource to the value of the parameter.

The value of this parameter will be something like:

[ "www.images.com/cat.jpg", "www.images.com/dog.jpg", "www.images.com/goldfish.jpg"]

How can I use this structure to assign these values to a Picture Box? I know ReportItem.DataObject exists, but I'm never quite sure how to use it, or if that's even the right approach. Guidance is much appreciated!

Thanks,
J.T.

Hello,

I am having an issue with creating a new style sheet in the web report designer. I would like to use a "StyleSelector" selector type, but when adding a new selector to the style rule, it defaults to "TypeSelector". How do I change this to be a "StyleSelector"?

Thanks,

Dan
