    Hi,

    I use the spreadsheet part with much satisfaction, but since a while I get the following error

    'Could not load file or assembly Telerik.Windows.Zip, Version=2016.1.106.40'

    And i can't get any solution. I tried to upgrade all Telerik controls, but that didn't work yet.I will try again...

     

    Can someone please help?

    It breaks on the last line of my code block.

    IWorkbookFormatProvider formatProvider = new XlsxFormatProvider();
     
    var workbook = new EpicExcelExportManager().GetFilledWorkbook();
    byte[] renderedBytes;
     
    using (var ms = new MemoryStream())
    {
        formatProvider.Export(workbook, ms);

     

    Thanks.

    John

    Hello,

    This error indicates problem loading the assembly.
    I would ask you to:

    1) Make sure you have referenced all the assemblies and they are with the same version.
    2) After 1) delete the Bin and obj folders of the project manually, Clean and Rebuild it.

    Regards,

    Hi Anton,

    Thanks. After a few tries this is solved.

    But now I am running into another issue.

    I have an Error: 'HtmlImportSettings' does not contain a definition for 'ImageRootPath'

    I use a htmlFormatProvider with HtmlExportSettings and HtmlImportSettings. But it seems there is not ImageRootPath property in the HtmlImportsettings. That is strange, because in your Api documentation it says there is.

    http://docs.telerik.com/devtools/winforms/api/html/t_telerik_wincontrols_richtextbox_formatproviders_html_htmlimportsettings.htm

    In the documentation it says it is in the dll below, but there is not such dll in the winforms package

    Telerik.WinControls.RichTextBox (in Telerik.WinControls.RichTextBox.dll) Version: 2016.3.1024.40 (2016.3.1024.40)

    So now I use it from:Telerik.WinForms.Documents.FormatProviders.Html

    See for the code:

    _htmlFormatProvider = new HtmlFormatProvider
    {
        ExportSettings = new HtmlExportSettings
        {
            DocumentExportLevel = DocumentExportLevel.Fragment,
            ImageExportMode = exportImages ? ImageExportMode.ImageExportingEvent : ImageExportMode.None,
        },
        ImportSettings = new HtmlImportSettings
        {
            ImageRootPath = $@"{Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)}\",
        }
    };

     

    Can you help me again?

    Hello , 

    Thank you for writing back. 

    Since R3 2016 SP1 (version 2016.3.1024) RadRichTextBox is removed from codebase. Please use RadRichTextEditor instead, which is an improved and much more feature rich replacement of the RadRichTextBox. Feel free to use the providers located in the Telerik.WinForms.Documents.FormatProviders namespace: http://docs.telerik.com/devtools/winforms/richtexteditor/import/export

    I hope this information helps. If you have any additional questions, please let me know. 

    Regards,
