    Good evening everyone.

    I'm trying to create new Web App then add 'Telerik Web Forms Report Viewer Forn R1 2019' to it.

    My problem is export option : it should have .xlsx, .docx and pptx

    Once I used R3 2018 , it work as I aspect

    I also attach image. export 2018 is what i use to do and what I expect and export 2019 is what i struck.

    PS. I'm not native English.

    Hello Atipong,

    Check if you have all of the required references listed in the Open XML SDK for Microsoft Office. You may also need to add a binding redirect in the Web.config file of the application through a piece of code like (when using DocumentFormat.OpenXml version 2.5.5631.0) :

    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="DocumentFormat.OpenXml" publicKeyToken="31bf3856ad364e35" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-2.5.5631.0" newVersion="2.5.5631.0" />
      </dependentAssembly>
    </assemblyBinding>

    For more information, you can refer to Missing DOCX, XLSX, PPTX, XPS export options KB Article.

    Note also that there is a known issue with our latest official release (13.0.19.116) described in the Telerik Reporting R1 2019 fails to load assembly DocumentFormat.OpenXml 2.7.2+ KB article.
