I have some table groups. I would like to hide the dynamic of each column group depending on the user option.
the example I have 3 groups
with 2 checkboxes.
if check box 1 = tick =>display group 1
if checked 2 box = tick =>display group 2
If I used <TableGroup Name="group28" Visible="True/False"> it can show/hide. But not dynamically
If I used like this. It can not work.
<TableGroup Name="group28">
                      <Bindings>
                        <Binding Path="Visible" Expression="= IIf( Parameters.InclAccessDetails.Value=True,False,False)" />
                      </Bindings>
Does TableGroup not support Visible with expression?
Thanks

This is no longer an issue. Is export fine with latest packages:
<PackageReference Include="DocumentFormat.OpenXml" Version="2.8.1" />
<PackageReference Include="Telerik.Reporting" Version="16.0.22.225" />
<PackageReference Include="Telerik.Reporting.OpenXmlRendering" Version="16.0.22.225" />
Problem was "xlxs" rather than xlsx".

CMD dotnet test.dll --environment developmentHi Friends,
 I am unable to render the  Telerik Report in the .net core App.
          ReportSource report = new InvoiceTest(); //calling from the dll
                    report.Parameters.Add("id", 1);
                    report.Parameters.Add("UserId", invoice.userId);
                
                    RenderingResult result  = reportProcessor.RenderReport("PDF", report,null);
                    if (!result.HasErrors)
                    {
                        string fileName = result.DocumentName + "." + result.Extension;
                        string path = System.IO.Path.GetTempPath();
                        string filePath = System.IO.Path.Combine(path, fileName);
                        using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
                        {
                            fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
                        }
                    }My error message like :
InnerException = {"Format of the initialization string does not conform to specification starting at index 0."}
your help on this would be greatly appreciated
Hi,
I am using Standalone Telerik Report Designer and trying to input a data into text box highlighted with red square (refer the attachment). I was inserting the textbox directly (look blue arrow) without inserting a table first as pageHeaderSection cannot be inserted with table. However, I found that No data source shown in the data explorer. Can someone guide me on how to input data into the textbox directly without inserting table first?
Thank you.

I have the requirement for setting a vector based picture (svg) as page background on every page in a report.
I tried setting the graphic as page watermark, but rendering the report as PDF the graphic is rasterized.
Is there another way of setting a vector graphic as page background and when rendering the report as PDF it stays vectorized ?
