If yes, then when I try to export, I get this error...

System.InvalidOperationException: {"Could not find neighbour element!"}

and the stack trace is at

Telerik.WinControls.UI.Export.ExportToExcelML.SearchForNeighbourElement(List`1 radElementList, Int32 index) at Telerik.WinControls.UI.Export.ExportToExcelML.CreateStyleElement(GridViewRowInfo gridViewRowInfo, Int32 cellIndex) at Telerik.WinControls.UI.Export.ExportToExcelML.CreateRowElement(WorkBookElement workbook, GridViewRowInfo gridViewRowInfo) at Telerik.WinControls.UI.Export.ExportToExcelML.AddWorkSheetWithHeaderRow(WorkBookElement workbook, FileStream fileStream, Int32& currentSheet, Int32& currentRow) at Telerik.WinControls.UI.Export.ExportToExcelML.RunExport(String fileName)


The code being used is
Dim cc As New ExportToExcelML(grid)
 cc.ExportVisualSettings = True
 cc.RunExport(saveFileDialog1.FileName)

Hi Deepak,

As far as I'm aware, exporting hierarcical data is not supported because Excel does not support hierarcical data. However, yuo should not be getting an error. The exporter should be just exporting the Master Tempalte rows.

Please can you try the following

Designer File
namespace RadGridView_hierarchy_C
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components;
  
        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
  
        #region Windows Form Designer generated code
  
        /// <summary>

        /// the contents of this method with the code editor.

Even though this is in C# (it's the quickest one I could come up with to get an answer to you) it should give you an idea to show that it can export, but only the top level rows.

Hi Richard,
 Thanks for your reply. Your code does not give me an error.However, I need to find a solution to export child templates on to excel. Infragistics supports it in a way by using the Display layout. I dont know why Telerik cannot find a solution. Microsoft not supporting does not carry support. At the very least, there should be a way of exporting the visual element, converting into HTML and exporting that to excel.

Thanks
Deepak

Thanks Richard, The thread doesnt really help me because it does not export the column definitions on to the spreadsheet. That is incredibly disheartening as the solution we are looking for needs to have the right column group headers on spreadsheets.
 I think we might also have a potential problem with printing if the column headers do not get printed.

Hi Deepak,

I'm sorry that this doesn't fulfill your requirements. I'll have a look as soon as I can to see if I can find any workaround, though this looks like quite a big one to try and solve. If I can come up with something that I think you would find useful, I'll let you know. In the meantime, I would suggest sending off a support ticket as a feature request (I haven't been able to find this in the Public Issue Tracking System).

Regards,
Richard

Hello Deepak,

I have answered already in your support ticket, but I am posting it here as well to be public available:

Curently we do not support exporting a RadGridView with ColumnGroupsViewDefinition or HtmlViewDefinition. We will consider adding this feature in one of the next releases.

As to the exporting hierarchical data, we are working on solution however I cannot give you a time-frame when it will be ready for release.

Looks like Telerik doesn't always get a chance to come back to these older threads. The ExportHierarchy feature is included in the latest release:

Is the hierarchical export available in Telerik ASP.NET Ajax as well?  The link above seem to be relevant to WinForm version of RadGridView...

Thanks,
