Hi Jack,

  I had a similar issue and is resolved in the "internal build" which I believe will be released in the next Service Pack?

Pradeep

Hi Divyesh Chapaneri,

We believe that we have addressed this exception in the latest internal build as Pradeep said. Currently, we have not plans for Service Pack release, but the fix will be available in the next major version Q3 2009. You can download the latest internal build from your account and give it a try.

All the best,

Hi Ufuk KARTAL,

Thank you for contacting us.

ExportToExcelML class does not support exporting grid with ColumnGroupsViewDefinition. We will include this functionality in one of the feature releases.

I have updated your Telerik points for bringing this to our attention. Do not hesitate to contact me again if you have any other questions.

Best wishes,

Hi, 
there's something new on this topic?

Hello Marcello,

Thank you for writing.

Currently, RadGridView does not support export to Excel functionality for ColumnGroupsViewDefinition. You can track the feature request's progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item. Since we have already introduced the Document processing library in the Telerik UI for WinForms suite we will consider this feature in the next releases.

I hope this information helps. Should you have further questions, I would be glad to help.

Desislava

Hello Marcello,

It seems that there is a duplicate of this feature request. Here is the feedback item for your reference regarding the export functionality of RadGridView view definitions (ColumnGroupsViewDefinition and HtmlViewDefinition) : ADD. RadGridView - add export of ViewDefinition. The votes are transferred accordingly.

Regards,
Desislava
Telerik

The feature request now shows a status of "completed" as of December 2015.  However, I can't find an example of how to implement this using VB.NET.

What version did this become available in?  I am using 2016.2.608.40.

Could you please provide an example of how to utilize this new feature?

Here is a generic code snippet that could be called from a button, etc. to export 'RadGridView1' which has a ColumnGroupsViewDefinition applied to it.

            With New SaveFileDialog

                .Filter = "Excel Spreadsheet (*.xlsx)|*.xlsx"

                .FilterIndex = 1

                .Title = "Export Grid to File"

                .FileName = fileName

                If .ShowDialog() = DialogResult.OK Then

                    Dim spreadExporter As New GridViewSpreadExport(RadGridView1)

                    Dim exportRenderer As New SpreadExportRenderer()

                    spreadExporter.ExportFormat = SpreadExportFormat.Xlsx

                    spreadExporter.SheetName = sheetName

                    spreadExporter.ExportVisualSettings = True

                    spreadExporter.SummariesExportOption = SummariesOption.ExportOnlyTop

                    spreadExporter.SheetMaxRows = ExcelMaxRows._1048576

                    spreadExporter.HiddenColumnOption = HiddenOption.DoNotExport

                    spreadExporter.HiddenRowOption = HiddenOption.DoNotExport

                    spreadExporter.FileExportMode = FileExportMode.CreateOrOverrideFile

                    spreadExporter.ExportViewDefinition = True

                    spreadExporter.ExportGroupedColumns = True

                    Try
                        spreadExporter.RunExport(.FileName, exportRenderer)
                        Process.Start(.FileName)
                    Catch ioEx As IOException
                        MessageBox.Show(ioEx.Message.ToString, "Info")
                    End Try

                End If

            End With

 

Thanks in advance.

Hello Kent,

Thank you for writing. 

I have prepared a sample project demonstrating how to export ColumnsGroupViewDefinition in RadGridView. Please refer to the attached screenshot illustrating the result on my end with the latest version. The following help article is quite useful as well: http://docs.telerik.com/devtools/winforms/gridview/exporting-data/spread-export

I hope this information helps. Should you have further questions I would be glad to help.

Hi Dess,

Thanks for responding so quickly.  Your sample project seems to work fine, but when I add in the two additional lines required in my code base the export still fails.

Two lines of code from your sample that I added into my project:

spreadExporter.ExportViewDefinition = True
spreadExporter.ExportGroupedColumns = True

For your knowledge, I had tried this prior to posting yesterday and it didn't work.  I then looked at the help article that you posted, and it didn't indicate that I was missing something.  Hence, my initial post about this.

Moving on... when I try to run the export, this line of code fails:

spreadExporter.RunExport(.FileName, exportRenderer)

This is the error generated:

System.ArgumentOutOfRangeException was unhandled by user code
  HResult=-2146233086
  Message=Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

       at Telerik.WinControls.Export.GridViewSpreadExport.RunExport(String fileName, ISpreadExportRenderer exportRenderer)
       at ******.Utilities.TelerikExportGridToExcel(RadGridView spread, String fileName, String sheetName) in ...

Does that help?  Am I missing something in the code that creates the viewDefinition?  The grid appears correctly.  I have attached a screenshot for reference.

Any help would be appreciated.

Thanks,

Kent

Also, your sample project was pointing to the same Telerik .dlls that I am using.  It was referencing the .NET framework 4.5 whereas my project is referencing 4.6.  I really don't know if that would make a difference, but wanted to let you know just in case.

Thanks,

Kent

Sorry for all the posts.

I have this running as a common routine which is utilized by many grids within the application.  Even with the two new lines of code that reference viewDefinitions and exporting column groups, it works fine with all the other grids.  This is the only grid that uses a viewDefinition to create column groups, and the only grid that the export fails on.

The first parameter in this routine is the RadGridView (which I presume also contains the viewDefinition).  The other two parameters are strings for the suggested filename and the sheetname.

Thanks,

Kent

Hello Kent, 

Thank you for writing back. 

I am still unable to replicate the error you are facing. It seems to be something specific in that particular grid. That is why I would kindly ask you to open a support ticket and provide a sample project demonstrating the issue. If it is more convenient to you, feel free to modify my sample project in a way to reproduce the exception. This would be the fastest way to make an adequate analysis of the problem and assist you further. Thank you in advance.

I am looking forward to your reply.
