Thanks Maria, but that sample doesn't really show how to use it within a form template. I hammered this out with a little bouncing back and forth with support and wrote the following code which seems to handle this quite well. Assuming the javascript from the sample you mentioned is already on the page....

Added the column:

    
            <telerik:GridAttachmentColumn MaxFileSize="5000000" DataSourceID="ResResDS" EditFormHeaderTextFormat="Upload File:" 
        
                                    HeaderText="Download" AttachmentDataField="uploadfile" AttachmentKeyFields="id" 
        
                                    FileNameTextField="FileName" DataTextField="filename" UniqueName="AttachmentColumn"> 
        
                                </telerik:GridAttachmentColumn> 
        
                            </Columns>

In my EditFormSettings - EditFormType="Template", nice boring HTML and then added the RadUpload control:

    
             <tr> 
        
                                            <td> 
        
                                                File Attachment: 
        
                                            </td> 
        
                                            <td> 
        
                                                <telerik:RadUpload MaxFileSize="5000000" runat="server" ID="FileUpload1" MaxFileInputsCount="1" 
        
                                                    AllowedFileExtensions=".zip,.jpg,.pptx,.docx,.doc,.xls,.pdf,.gif,.ppt,.txt,.csv" 
        
                                                     ControlObjectsVisibility="None"> 
        
                                                </telerik:RadUpload> 
        
                                            </td> 
        
                                        </tr>

In the code behind:

    
                    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
        
                    { 
        
                        if (e.CommandName == RadGrid.UpdateCommandName || e.CommandName == RadGrid.PerformInsertCommandName) 
        
                        { 
        
                            GridEditFormItem gridEditFormItem = (GridEditFormItem)e.Item; 
        
                            if (!(gridEditFormItem is GridEditFormInsertItem)) 
        
                            { 
        
                                recid = (int)gridEditFormItem.GetDataKeyValue("id"); 
        
                            } 

            //If more than one file is allowed, change to foreach 
        
                            RadUpload radUpload1 = (RadUpload)gridEditFormItem.FindControl("FileUpload1"); 
        
                            if (radUpload1.UploadedFiles.Count > 0) 
        
                            { 
        
                                UploadedFile uf = radUpload1.UploadedFiles[0]; 
        
                                filedata = new byte[uf.ContentLength]; 
        
                                uf.InputStream.Read(filedata, 0, filedata.Length); 
        
                                filename = System.IO.Path.GetFileName(uf.FileName); 
        
                            } 
        
                        } 
        
                    }

Now that sample will work in an edit form template :).
Thanks,
