Hello!

I have designed a table inside a Group Header.

Now I want to filter the datasource of the table with the key value of the group header.

How can I make this?

I create my report form  and it can export docx file (click preview mode and select export with "Word Document").

but after I resize textbox43 to fit content, it get the corrupt docx file. How can I solve this problem . 

I recently upgraded by ASP.Core beta web project to an ASP.NET Core 2.0 application with an ASP.NET Core 2.0 API behind it.

Before the upgrade, my Telerik reports ran fine.

Now, the HTML5 viewer appears, and throws the following error:

"Error registering the viewer with the service. An error has occurred. The type initializer for 'Lock' threw an exception."

In Chrome developer's console, the following javascript error shows:

1#:1 Uncaught (in promise) Invalid cliendID
Promise.then (async)
refreshReport @ telerikReportViewer-12.0.18.227.js:1442
start @ telerikReportViewer-12.0.18.227.js:5417

I have followed the exact steps from here to support ASP.NET Core 2.0 apps:

https://docs.telerik.com/reporting/html5-report-viewer-asp-net-core-2#html5-report-viewer-in-asp-net-core-2

Any ideas what the error means and how to fix it?

Thanks!

I get this error when I load a report from internal IIS 10 server, on my local developer machine it works : 

Unable to get report parameters

                reportSource: {
                    report: "IntraReport.Arr_Bekraeft, IntraReport",
                    parameters: { ID: @Model }
                },
                viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
                scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
                scale: 1.0,
                ready: function () {
                    //this.refreshReport();
                }
            });

        sqlConnection1.Open()
        sqlDataAdapter1 = New SqlDataAdapter("exec [daterange_report] '8/25/2009','8/27/2009' ", sqlConnection1)
        Dim dataSet As New DataSet()
        sqlDataAdapter1.Fill(dataSet)
        Me.DataSource = dataSet.Tables(0)
    End Sub
End Class

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
      
        Dim report As IReportDocument
        report = New Report1()
        Me.ReportViewer1.Report = report
        ReportViewer1.DataBind()
       
End Sub

Please give any suggestions to solve it.

Thanks in advance.

I need to consume an API and pass parameters using the POST method.

Placing a query via POST
Where I hope in the message body an object with an integer attribute PatioID.

When I configure the datasource, I inform the URL and Parameters via POST, when I command to execute of the error. (415 - unssupported media type )

Dear All,

I created a cross tab report that results in a single grid that is sometimes longer than one page. When it is less than one page, the cross-tab grid begins on page one. But when it is greater than one page, it leaves the first page blank and starts on the second page. How do I make it start on the First page regardless?
I removed the "keep together" in the section expert and I was told about a "Keep Object Together" in the Cross tab expert but I did not find it in there but I did find a "keep columns together". But none of that fix it.
Help?
Thanks.

I need to create a chart that contains a column chart and two line charts imposed over the column chart.  The data set that I am working with looks like the one I have attached in the data.jpg image and the chart should look similar to the one in the chart.jpg that is attached.  I have been trying to figure out how to make this work but all to no avail.  If someone has any tips on how to get the chart designed I would appreciate it.
