Hello,

i am using Telerik R1 2017 and created many reports. by default the background color of the report viewer is white. i want to change the background color of the report viewer so that the report stands out. 

i tried below mentioned style

    <style>
        #reportViewer { 
            position:absolute;
            left: 5px;
            right: 5px;
            top: 5px;
            bottom: 5px;
            font-family: 'segoe ui', 'ms sans serif';
            overflow:hidden;
            z-index:-1;
            background-color:ivory;
        }
    </style>

this does sets background color but now the main report is not visible at all. i can only see the color i have selected as background color.

Kind Regards,

Savan K. Parmar

I'm not sure where else to put this.  My users (usually using IE 10/11) have random issues when trying to view a report.  Sometimes they come up fine and sometimes they don't.  I've seen some similar issues related to the report cache but I can't figure it out.  One thing I did notice is that the site is HTTPS but the reportviewer request URL is http.

Here are the exception details:

I created a Rose Radar Graph to mimic a Polar Graph, I have the angular axis labeled at each 90 degree interval with a max of 360 degrees. Is there a way to add 180 to that value? also, the Graph Axis lines aren't showing as I want them too, i've attached a screenshot as well. 

Where the 0 is on the top, I want to display 180, 90 -> 270, etc. The axis lines I want to be a cross versus the x like configuration they are in now. 

Hi,

I'm having problem with a graph in a report. The lables get mixed together. See attached image.

Best regards,

When I generate my pie charts, sometimes all of the labels get stacked on top of one another and it shrinks the pie chart down to a tiny size to make room for all of them.

Is there any way to get the chart to move some to the left and some to the right so it doesn't do this?  See the attached image, compare the size of each pie chart and notice how one of them has 6 labels stacked in one spot

Thanks

I'm having trouble with re-running reports and the export button.  In this scenario, hitting the export button will export all previously opened version of the report, so you end up with multiple exports.  Here's the setup:

Lets say you create a telerik report and you have some kind of a parameter building UI.  You run the report and it opens up below your parameter building section.  Then you decide you want to add one more thing, you add the new parameter and run your report again.  The report correctly loads with the new parameter.

In both runs the report executes on the same element.  On run, it clears the data from the element with the following line of code: myReportData.removeData();.  After which it recreates the report. 

However, when you click "export to pdf", you get a pdf from both versions of the report.  It's as if the binding to that button still exists and the report is cached.  If it is a binding how can I remove it? If the file is caches somewhere, how can I delete that cache?

We are creating report for our Web application and We have following Issues:

Date Format issue  as default it always give (4/27/2017) - (MM/dd/yyyy) we need to Customize the Date format as (dd/MMM/yyyy).

I need to add Date validations in the report viewer is it possible, if So Share me the Sample code for it.

Hello,

currently i perform some tests with the reporting features but i have some questions about the licensing the exact differences etc.

I have a Windows Service as Server and as client a WPF Application. The communication works over two Web-Services (one for each side). This architecture is well tested and works very fine for our purposes.

Lets go to the questions:

1. i want to have the reports on all clients. The delivery of the reports should perform from my own Windows Service. Is it possible to implement a simple Webservice to render and manage the reports on the server side? Is the documented REST/WCF Reporting-Service the right one to choose? Or do we have to buy the report server as well?
2. I want to use the Standalone Report designer for creating and administrating the reports. Is it possible to connect the ReportDesigner to the above mentioned Webservice?

Thanks,

Michael

Hello all!
Could anyone help me out to provide a list of which Telerik version (Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms) is compatible with which .Net Framework? I tried finding it out a lot on net but couldn't obtain any concrete results.

My company is using Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=6.2.12.1025. Application is currently built on .Net Framework 3.5 using VS2008.. We are looking forward to upgrade the application to .Net Framework to 4.5 using VS2012. But am not sure if this version (6.2.12.1025) will support .Net Framework 4.5.

Any kind of help is appreciated.

Thank you.

Regards,

Nayana
