Blazor Reporting - Parameters not visible by default

[Andrew]

Telerik Reporting - Telerik.ReportViewer.Blazor Version 14.0.20.115

This is the entirety of the page on which the ReportViewer is displayed:

 

<ReportViewer ViewerId="reportViewer1"
              ReportServer="@(new ReportServerOptions {  Url = "https://reporting.$WEBSITE.com", Username = "$NAME", Password = "$PASS" })"
              ReportSource="@(new ReportSourceOptions()
                            {
                              Report = "Foundation/LicenseUsages.trdp"
                            })"
              ParametersAreaVisible="true"
              ScaleMode="@(ScaleMode.Specific)"
              Scale="1.0" />

 

Expected behavior: The parameters area should be visible when the report loads.

Observed behavior: The parameters area is not visible by default, even though the button on the ReportViewer implies it should be. The button must be toggled off then on again to see the parameters area.

Hi Andrew,

I was able to replicate this locally and have attached a short video that displays the behavior. I believe this is caused by the Parameter Options from within the report. Can you confirm that the Visible property is set to true as shown in the below screenshot? Note that if this is set to true, the ParametersAreaVisible property from the Report Viewer defaults to true and can be safely removed.

If the issue still persists after confirming the property value, I will need to review a sample report that produces the same behavior. 

In the meantime, please let me know if you need any additional information. Thank you for using the Reporting Forums.

Hi Eric,

Both parameters have Visibility = true set in the Report Designer. This issue happens regardless of ParametersAreaVisible being explicitly set in the blazor markup.

Hi Andrew,

Thank you for confirming the Visibility property is set to true in the report. Although, without a sample that reproduces the same behavior I am unable to troubleshoot this in great detail. Let me provide a couple of troubleshooting options below.

1. I have attached a working sample that can be used for comparison. To get started, I recommend verifying the references are identical between the projects. To run the sample ensure the Telerik NuGet Feed is configured in Visual Studio. Can you let me know if you find any differences between the two projects?

2. Another option is to preview the Report through the Report Server UI. If the parameters area is not visible there this could be the result of a custom template on the Report Server machine. Can you confirm that the Parameter Area is visible during preview?

In the meantime, please let me know if you need any additional information. Thank you and I look forward to your reply.
