HI,

   I tried to export from my winform radgridview data which contains view definition using example provided in link https://docs.telerik.com/devtools/winforms/controls/gridview/exporting-data/spread-export. Once I tried this code application is not compiling. There were no errors in output window when we carefully checked I found that there is an error related to SpreadExportRenderer. The error was "error BC30002: Type 'Telerik.WinControls.Export.SpreadExportRenderer' is not defined". My TelerikExport.dll version is 2016.1.216.20. Can you please help me out how to solve this issue.

Regards

Hello, Harsha,

It seems that use GridViewSpreadExport. The spread export functionality is located in the TelerikExport.dll assembly which must be added to your project. You need to include the Telerik.WinControls.Export namespace in order to access the SpreadExportRenderer.

Then, you can use the following code snippet to export the grid:

  private void radButton1_Click(object sender, EventArgs e)
  {
      GridViewSpreadExport spreadExporter = new GridViewSpreadExport(this.radGridView1);
      SpreadExportRenderer exportRenderer = new SpreadExportRenderer();
      spreadExporter.FileExportMode = FileExportMode.CreateOrOverrideFile;
      spreadExporter.RunExport("D:\\exportedFile.xlsx", exportRenderer);
      Process.Start("D:\\exportedFile.xlsx");
  }

I hope this helps. Let me know if you have other questions.

Hello, Harsha,

Yes, the TelerikExport.dll is available in the 2016.1.216.20 version. You should carefully check in your installation folder:

I would encourage you to upgrade to the latest version if possible. Thus, you can benefit from all the introduced improvements since 2016. The latest version is 2020.3.1020.
