CR SP26 VS2019 Parameter Panel Missing Parameters

[kevin_hicks]

I have run the the update to SP26 for some reason my parameters are no longer showing up in the parameter panel on the web crystalreportviewer after the report has initially loaded. The parameter(s) is prompted initially to run the report.

As a work around I have set HasToggleParameterPanelButton= false, HasRefreshButton=true, and ReuseParameterValuesOnRefresh=false.

<CR:CrystalReportViewer ID="Report" Runat="server" AutoDataBind="true" Height="1250px" HasCrystalLogo="False" HasRefreshButton="True" HasToggleParameterPanelButton="false" BestFitPage="True" ReuseParameterValuesOnRefresh="false" ToolPanelView="None" DisplayStatusbar="True" HasToggleGroupTreeButton="false" EnableDatabaseLogonPrompt="False" PrintMode="ActiveX" />

This does show the parameter(s) as expected. My report parameters are set to editable and when you loop through the parameterfield using the code below the Usage2 values is already set to all the available values (side note, this snip came from another post, but if you try it you will get a Not Supported exception)

foreach (CrystalDecisions.Shared.ParameterField parameterField in reportDocument.ParameterFields)
{
  parameterField.ParameterFieldUsage2 = ParameterFieldUsage2.ShowOnPanel;
}

As you can see from pic here the parameter for this report is missing from the Parameter Panel. Not sure how to fix this issue. Any suggestions would be appreciated. Thinking it might be a bug. I included my code below for reference. Prior to SP25 I was clearing the parameterfieldinfo property using Report.ParameterFieldInfo.Clear() in the report init method. This might have something to do with the missing parameters, but I have no way of testing, because if I add that back I cannot get the report to load as when you click the OK on the parameter dialog the report's ajax postback just returns the parameter dialog back instead of the rendered report.

Notes about my upgrade:

I ran the exe as the admin as instructed. I let it install the 64bit msi. The 32bit msi was already installed, but did not get updated. I updated it manually. The VS toolbox still has the .3500 controls referenced so I removed them and added the new items (not sure if that was suppose to happen automatically). I did remove all my references in the image below and added them back which updated the project file to the .4000 dll's.

So I have made some progress. I have updated my viewer to the following:

<CR:CrystalReportViewer 
           ID="crReportViewer" Runat="server" AutoDataBind="True" Height="1250px" HasCrystalLogo="False" BestFitPage="True" DisplayStatusbar="True" ToolPanelView="None" PrintMode="ActiveX"
           EnableDatabaseLogonPrompt="False" 
           ReuseParameterValuesOnRefresh="True" 
           HasRefreshButton="True" 
           HasToggleParameterPanelButton="True"
           HasToggleGroupTreeButton="True" 
           /> 

Now the parameters are showing in the parameter panel and the report is loading correctly after the original parameter prompt closes. However, now whenever there is a postback on reports that includes optional prompts in the report, the parameter prompt is shown again with just those optional parameters. He is an example of the flow.

1. Load report in web viewer that include 4 parameters, 2 of which are optional
2. Built-in viewer parameter dialog shows and only the required parameters are picked and click OK
3. Report loads in viewer correctly.
4. Any postback is fired from viewer (this example let's say you click Next Page button)
5. Built-in viewer parameter prompt appears with only the 2 optional parameters
6. You just click OK and the prompt closes, but you are still on page 1.
7. You click Next Page again, but this time when the 2 optional parameters appear you select values for both and click OK. 8. Report not loads with values set for all 4 parameters.
9. You not click Next Page again, but this time you are shown page 2 as expected.

So it appears to me something is up with the optional parameters after the initial loading of the report. Here is my code that handles my report loading. I cannot figure out what I am doing wrong. Like I said before this all worked prior to SP25. Something has changed and I am not sure what I need to do now for the optional parameters not to appear after the report is loaded unless I pick the parameter from parameter panel.

            If rpt IsNot Nothing Then rptPath = Server.MapPath("~/reports/cr/" + rpt)
            If rptPath IsNot Nothing Then

                    crReportDoc = New ReportDocument

And just to be clear. I can load this very same report is optional parameters in CR 2013 SP12 and after the initial parameter selection I go directly to page two without getting prompted for the optional parameter. So this would make me believe nothing is wrong with the actual report itself.

Is there any resolution to this issue? I am having the same problem with my reports. Parameter panel is missing parameters.

Ok don.williams I have run the processmonitor, but I have no clue what I am looking for. I ran it just on iisexpress and only when I clicked the next page button in the crystal report viewer and when it prompted for the optional parameters I clicked stop on the process montior. Captured 42000 events. Should I filter those events with just SAP in the path? I am going to start reviewing now just to see if I can find anything that makes sense.

Also, I added two additional notes to the main question. I am starting to believe this might a bug related to handling optional prompts (parameters). Thanks for the help so far!

[kevin_hicks]

don.williams so now I am really thinking this might be a bug with SP26. Will you please see if you can reproduce the optional prompt issue?

I have attached a sample project. (sample project here) This project was created using the crystal reports website template. I have one test.rpt file. Run the project and select the Name property only. Once report loads, then click next page. You should get a prompt for Color which is the optional parameter. If you just hit ok, then window closes but still on page 1. If you select a color it updates the report, but still on page 1. Only then can you click next page and page 2 will load.

My project is a web app and this a newer website project, so I am convinced it has to be a bug. Hopefully you will get the same results.

Don't forget to add the asp_net virtual directory to the vs/applicationhost.config file so the viewer loads. I also updated the physicalPath, but you might have to update that too if VS doesn't do it for you.
