Hello,

Today i have made an update from R1 2018 to R3_2020_SP1_14_2_20_1021_DEV and now all my reports does not behave as usual.

For instance, a simple data ItemDataBinding of a PictureBox to populate the phisical path of an image is not working ... 

Same thing to htmltextbox ... it is not puting the value with ItemDataBinding to the report.

Can you help me? What do you need from me to solve my situation?

This is my code, that in the version R3 worked:

    Private Sub PictureBox3_ItemDataBinding(sender As Object, e As EventArgs) Handles PictureBox3.ItemDataBinding

        Dim item As Processing.ReportItemBase = DirectCast(sender, Processing.ReportItemBase)
        If IO.File.Exists(System.Configuration.ConfigurationManager.AppSettings("Images").ToString() & "cabecalho.PNG") Then
            PictureBox3.Value = System.Configuration.ConfigurationManager.AppSettings("Images").ToString() & "cabecalho.PNG"
        End If

    End Sub

    Private Sub HtmlTextBox12_ItemDataBinding(sender As Object, e As EventArgs) Handles HtmlTextBox12.ItemDataBinding

        Dim item As Processing.ReportItemBase = DirectCast(sender, Processing.ReportItemBase)
        If IO.File.Exists(System.Configuration.ConfigurationManager.AppSettings("Images").ToString() & "contrato_header.txt") Then

            Dim fileReader As String
            fileReader = My.Computer.FileSystem.ReadAllText(System.Configuration.ConfigurationManager.AppSettings("Images").ToString() & "contrato_header.txt")
            HtmlTextBox12.Value = fileReader

        End If
    End Sub

Thanks,

Nuno

hi

I tried to use angular report viewer + dotnet core 3.1 to represent my report in Linux. The sample I refer to is
AspNetCore3 AngularReportViewer.zip ,

angular report viewer：11.20.1021

Telerik Reporting：14.2.20.1021

But I had two problems,
1，Set for .trdp definition

Error：Unable to get report parameters. An error has occurred. Type: Telerik.Reporting.ReportSerialization.V4_0.ReportSerializable`1[Telerik.Reporting.Report]
2，Set for Core Library definition

Error：Unable to get report parameters. An error has occurred. Invalid report type

Please refer to the attachment for details.

I want to know what caused my mistake and what I should do.
thank you.

I have a multicolumn report that I would like to have leading dots between the two fields, but I can not find setting in the designer.  How do I get the report designer to add leading dots between fields?  

Item #1 ...... Reference

Item #2 .. Reference #2

Hi all,

I hope that you can help me.
I want to start using Redis cache for my reports but the initial few tests seem problematic as the entries in Redis have a TTL of -1 and therefore also never expires. I must be doing something wrong, any help would be appreciated.

Tech. stack:

• ASP.NET Core 3.1
• HTML5 Report Viewer
• Telerik Reporting Version 14.2.20.916
• Telerik.Reporting.Cache.StackExchangeRedis.2 Version 14.2.20.916

Code sample of the report configuration:

I created DataMatrix on Report Designer R3 2020 at next settings

    Encoder:  DataMatrix

    Encodation: Ascii

    SymbolSize: SquareAuto

    TextEncoding: Unicode (UTF-8)

    Module: 2pt

    Value:1

But, it could not read by barcode reader.

If the SymbolSize is "RectangleAuto", it can be read. But, I should be use "SquareAuto".

And, my barcode reader can read the same type DataMatrix generated by other web site generator .

Curiously, the DataMatrix for Reporting Designer reports and the DataMatrix for other websites are in the form of mirrors.

Can anyone tell me what's wrong?

Hello Telerik Team,

I am using Telerik Standalone Designer.

IsNull Function is not working for me.

=IsNull(Fields.status, " ") 

My Response is "status": null,

It showing an error like this. "textbox cannot perform "=" Operation on Newtonsoft.Json.Linq.Jvalue and System.String"

i have attached screenshot of the error for the more information to help you.
Please Reply as soon as Possible.

Thanks In Advance.

I'm using a JsonDataSource, InlineData, and I'm trying to edit/paste JSON in the data field. This is resulting in a 500-error stating that the parameter stream cannot be null. This only happens when I edit this data field. If I edit other parts of my report, everything is fine.

It seems like this is a front-end error, because if I set a breakpoint on the Save-function it seems to Base64-encode this field unless I try to edit it manually. If I paste in the data as Base64-encoded, it saves as normally and displays correctly upon refresh.

Is this a bug, or is there something wrong in my setup?
