I'm using a HTML5 Web Forms Report Viewer

Here is my code:

            var reportPackager = new ReportPackager();

            var reportInstance = new Report();

            using (var sourceStream = System.IO.File.OpenRead("PathToTRDPFile"))

            {

                reportInstance = (Report)reportPackager.UnpackageDocument(sourceStream);

            }

            var table3 = reportInstance.Items.Find("table3", true)[0] as Telerik.Reporting.Table;

            table3.DataSource = CreateDataTable(); //A function that returns a datatable

            var instanceReportSource = new InstanceReportSource { ReportDocument = reportInstance };

            this.reportViewer1.ReportSource = instanceReportSource;

The error that I got: 

Error CS0029 Cannot implicitly convert type 'Telerik.Reporting.InstanceReportSource' to 'Telerik.ReportViewer.Html5.WebForms.ReportSource'

Any idea on how to resolve this?

Hi,

I'm trying to install our application and one of the dependencies is Telerik.UI.for.AspNet.Core.  Our application is set up to work with version 2020.2.513 but when I build the app it automatically pulls down version 2021.3.914 (we're connecting through a feed).  The dependency is showing the warning that the app depends on 2020.2.513 and the approximate best version was found.  When I go to the Nuget Package Manager there are only three versions available, all from 2021.  Is it possible to pull down the specific 2020 version?

Thanks,

Nate

Recently I created a report.  The report was linked to a stored procedure in MS SQL.  When I would fire off the SPROC the data would return.  One issue I had with my SPOC was 1 column name was duplicated.  I had for example "column_1" in my output twice.  I know this is a bad design on the query, but it's even worse that telerik report designer just returns "No page to display".

The report designer lacks error messages, or anything to point to where the issue was.  Your message of No page to display is to generic.

Today I'm working with another issue.  I have a SPOC with 1 field being outputted, when I run the query in SQL it works.  When I run the in the data source setup to execute top 10, it works.  When I run the report in Preview mode, the generic error No page to display.  I have found no event logs, no information as to where I can see where the designer is getting stuck or not liking the data.  

Hello...

I have a report where pixel-accurate placement is critical. I understand the basic CanGrow functionality, how text boxes will grow with more data, how they will cause a panel to expand accordingly, etc. What I'm facing is a situation where I need to display ONLY upper-case letters or numerals toward the bottom of the panel, so there will be no descenders. I have the textbox set to CanGrow = False and CanShrink = False. But when I use a larger font (set dynamically), one that will display the characters properly in the report, the textbox DOES grow, causes the parent panel to grow, and destroys the rest of the report placement. 

You'll see in the attached partial screenshot of a preview that the item on the left has a textbox that has grown and caused the panel (in orange) to grow. What I believe it should do is NOT grow, even if that means it cuts off any descenders. Various threads and docs have said that a textbox would not grow with CanGrow set to false, but in this case it most definitely does. 

So... Is there a way to set a panel to a fixed size in some other way. I have every object in that panel set to CanGrow = False, but it does not seem to matter.  Can I set the Height programmatically in some way that will override the CanGrow internal logic? I've tried setting it in the Bindings, but it seems to get overridden.

I'm using Reporting R2 2021.

Any help is much, much appreciated!!! Cheers...

Hi,

As per screenshot I attach, on the screen, users have to do some filtering then click on Generate button to show the report.

However, there is an intermittent issue when user generate report, which is "Document/refresh with ID 'xxx' not found". Users have to refresh the screen or click on Generate button again.

Please advise how can we resolve the issue.

Thank you.

Upgraded Telerik Reporting DLL version From 12.1.18.516 to 15.1.21.616 But it doesn't show textbox data that comes from ItemDataBound or ItemDataBinding.

I am using report in asp.net vb project.

Please suggest solution

I have a dataset coming back:

Group      GrpAmt

PArent    $10.00

Standard $5.00

2 columns and 2 rows come back. Should this be formatted another way?

I have attached to the chart object but I am not getting the expected pie pieces.

Instead I get 2 round circles within each other. Not the doughnut version, changed to that and just got an extra white circle in the center.

How do I get the chart to show me the pieces?
