Hi everyone,

I'm working with Telerik Report Designer, and I have a table inside a panel. The panel represents the entire page that gets printed. The table is bound to a JSON data source.

In my JSON data, I have several objects, and some of them have a value of 0.0 If two specific objects have a value of 0.0 I want to hide the panel (and therefore the entire page) to avoid printing out a table with no meaningful values.

The data source is linked to the table, not to the panel, so I am not sure how to make this condition work. I need to hide the panel based on the values within the data.

Does anyone have any idea how I can set up conditional formatting or report parameters to achieve this?

Thanks in advance!

We are trying to create a user interface with UI for Blazor that allows users to view and choose parameter values for their reports without having to go into the report viewer. However, the complexity of some of the expressions used for things like display value, available value filtering, and default values pose a challenge to evaluating those parameters ourselves. Is there a way to programmatically evaluate those parameters for the above using the telerik reporting library so that we can display them in our UI?

We are using the Telerik.Reporting.Report object to get the parameter data, and have also tried instantiating a InstanceReportSource for the object as well but both have only given the expression for display value/available values/default values rather than the evaluated values.

Has anyone tried to append a pdf page when a report is generated or printed, is there any solution to this issue?

Hi

Using telerik report in react, showing report in Report Viewer and all fine.

Now need to get the PDF (inline, not download) of this report from Report Viewer programmatically. (Not in backend). Is there is a way to get the PDF.

I can download PDF using viewer.current.commands.export.exec("PDF"); but i need to get pdf contents. (need to upload to azure blob)

Also when we export PDF manually, ReportViewer calls the CreateDocument endpoint  [HttpPost("clients/{clientID}/instances/{instanceID}/documents")] 

to get the document id. and then uses clientid, instanceid and documentid to get pdf.

In react how can we get the client id and instanceid from Report Viewer.

Thanks

Hello all!

I have what feels like a very simple example of using 2 cascading parameters in a report. The first parameter is loaded with no issue but come time for the second, I get a "Response status code does not indicate success: 400 (Bad Request)".

I notice in the REST service call that it is passing hasChildParameters as false. I don't see an option to set that as true.

I've found when I run the download in designer with matching values that are expected in the parameter it retrieves without issue. This is purely a runtime issue.

Here are a few screenshots of what I have setup. Any advice is appreciated.

hi,

    I want to display a report book with the .trbp suffix in the ReportViewer component of Telerik UI For Blazor, but when I assign the ReportSource, it prompts that it cannot be converted from Telerik.Reporting.UriReportSource to Telerik.ReportViewer.Blazor.ReportSourceOptions. Is there any specific case reference?

<ReportViewer ViewerId="rv1"
              ServiceUrl="API/Reports"
              ReportSource="@BookReportSource"
              Parameters="@(new ParametersOptions { Editors = new EditorsOptions { MultiSelect = EditorType.ComboBox, SingleSelect = EditorType.ComboBox } })"
              ScaleMode="@ScaleMode"
              ViewMode="@ViewMode"
              PageMode="PageMode.SinglePage" />

public object BookReportSource { get; set; } = new Telerik.Reporting.UriReportSource()
{
    Uri = $"{ReportParameters.ReportName}.trbp"
};

protected override Task OnParametersSetAsync()
{
    switch (ReportParameters.ReportName)
    {
        case nameof(Report.StaffCapitalisationRatioReport):
            BookReportSource.Parameters.Add("StartDate", ReportParameters.StartDate);
            BookReportSource.Parameters.Add("EndDate", ReportParameters.EndDate);
            BookReportSource.Parameters.Add("BusinessUnit", ReportParameters.BusinessUnit);
            BookReportSource.Parameters.Add("FormatDate", Convert.ToDateTime(ReportParameters.EndDate).ToString("yyyy / MMMM"));
            BookReportSource.Parameters.Add("StaffNo", ReportParameters.StaffNo);
            BookReportSource.Parameters.Add("NormalWeekdayHours", ReportParameters.NormalWeekdayHours);
            BookReportSource.Parameters.Add("NormalWeekendHours", ReportParameters.NormalWeekendHours);
            break;
    }

    return base.OnParametersSetAsync();
}
