Hi there,

I'm new to Telerik Reporting and I'm building a report that shows a list of images. The images are uploaded from a mobile app, processed, and then are made available to be displayed on the report.

In some cases there could be an issue with the processing and the image file is not available or the processing hasn't completed yet before the report is executed. In this case I would rather display nothing than the big red error message that shows when the image can't be found. Is there a way for me to suppress this message somehow?

I've attached a sample of the error message.

Thanks for the help,

Greg

How to get rid of this Error without copy subreport's trdp file in to debug folder ?

I successfully make an example Winforms App which is taking parameters from user and then exports report which has a subreport to pdf. But I have an problem which I can solve just by putting the subreport's trdp file in the debug folder which is in the project. But I want to put subreport's trdp file where I want to put without getting the error. How can I do that ? I will attach the error I am getting. The error is written in Turkish. But It basically says I couldn't find the file "C:\Users\OE\source\repos\TelerikReportsDenemeForm\TelerikReportsDenemeForm\bin\Debug\denemereportabv.trdp".

Here is my code :

Formatting the Zip code depending on size

I have a report (trdp) with a zip code field. some of the data has the zip code saved as 5 digits some have 9 (ie. 12345-4578). If the data length is 5 I want the report to display 01245 if it's length is > 5 I want to display 01245-7845.

How would one acomplish this without using a user defined function?

Setting ReportSource parameter does not set the ReportDocument parameter value.

PLEASE VIEW THE ATTACHED SCREEN SHOT.

Setting ReportSource parameter does not set the ReportDocument parameter value.

Why is the parameter value not flowing to the ReportDocument as the docs state it does?

Thank you!

How can I set the DataSource at runtime?

I have a TRDP or TRDX that I have resolved at runtime.

These TRDP and TRDX objects don't expose anything except parameters. Not sure why this is.

How can I set the DataSource at runtime?

(please don't ask why I want to do it, I just need to, thank you)

How to get report parameters in default constructor

Does anyone know how to get the value of report parameters in the default report constructor? I am using Telerik.ReportViewer.Html5.WebForms. You used to be able to get it by the example below but this no longer works. Is there another way to get a reference to a parameter within the default constructor?

    public partial class Report1 : Telerik.Reporting.Report
    {
        public Report1(int month)
        {
            //
            // Required for telerik Reporting designer support
            //
            InitializeComponent();

            //
            // TODO: Add any constructor code after InitializeComponent call
            //

           int MonthParam = month;
        }
    }
