    <p>I'm exporting an ASP.NET gridview to Excel using the following function. The formatting is working really well, except I need to freeze the header row in Excel on the export. I'm really trying to avoid using a 3rd party Excel plugin for this, but unless there's some archaic excel markup in my AddExcelStyling function. </p> <pre><code> Public Sub exportGrid(ByVal psFileName As String) Response.Clear() Response.Buffer = True Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.ContentType = "application/vnd.ms-excel" Response.AddHeader("content-disposition", "attachment;filename=PriceSheet.xls") Response.Charset = "" Me.EnableViewState = False Dim sw As New StringWriter() Dim htw As New HtmlTextWriter(sw) sfggcPriceSheet.RenderControl(htw) Response.Write("&lt;meta http-equiv=Content-Type content=""text/html; charset=utf-8""&gt;" + Environment.NewLine) Response.Write(AddExcelStyling()) Response.Write(sw.ToString()) Response.Write("&lt;/body&gt;") Response.Write("&lt;/html&gt;") Response.End() End Sub </code></pre> <p>And the formatting black magic:</p> <pre><code> Private Function AddExcelStyling() As String Dim sb As StringBuilder = New StringBuilder() sb.Append("&lt;html xmlns:o='urn:schemas-microsoft-com:office:office'" + Environment.NewLine + _ "xmlns:x='urn:schemas-microsoft-com:office:excel'" + Environment.NewLine + _ "xmlns='http://www.w3.org/TR/REC-html40'&gt;" + Environment.NewLine + _ "&lt;head&gt;") sb.Append("&lt;style&gt;" + Environment.NewLine) sb.Append("@page") sb.Append("{margin:.25in .25in .25in .25in;" + Environment.NewLine) sb.Append("mso-header-margin:.025in;" + Environment.NewLine) sb.Append("mso-footer-margin:.025in;" + Environment.NewLine) sb.Append("mso-page-orientation:landscape;}" + Environment.NewLine) sb.Append("&lt;/style&gt;" + Environment.NewLine) sb.Append("&lt;!--[if gte mso 9]&gt;&lt;xml&gt;" + Environment.NewLine) sb.Append("&lt;x:ExcelWorkbook&gt;" + Environment.NewLine) sb.Append("&lt;x:ExcelWorksheets&gt;" + Environment.NewLine) sb.Append("&lt;x:ExcelWorksheet&gt;" + Environment.NewLine) sb.Append("&lt;x:Name&gt;PriceSheets&lt;/x:Name&gt;" + Environment.NewLine) sb.Append("&lt;x:WorksheetOptions&gt;" + Environment.NewLine) sb.Append("&lt;x:Print&gt;" + Environment.NewLine) sb.Append("&lt;x:ValidPrinterInfo/&gt;" + Environment.NewLine) sb.Append("&lt;x:PaperSizeIndex&gt;9&lt;/x:PaperSizeIndex&gt;" + Environment.NewLine) sb.Append("&lt;x:HorizontalResolution&gt;600&lt;/x:HorizontalResolution" + Environment.NewLine) sb.Append("&lt;x:VerticalResolution&gt;600&lt;/x:VerticalResolution" + Environment.NewLine) sb.Append("&lt;/x:Print&gt;" + Environment.NewLine) sb.Append("&lt;x:Selected/&gt;" + Environment.NewLine) sb.Append("&lt;x:DoNotDisplayGridlines/&gt;" + Environment.NewLine) sb.Append("&lt;x:ProtectContents&gt;False&lt;/x:ProtectContents&gt;" + Environment.NewLine) sb.Append("&lt;x:ProtectObjects&gt;False&lt;/x:ProtectObjects&gt;" + Environment.NewLine) sb.Append("&lt;x:ProtectScenarios&gt;False&lt;/x:ProtectScenarios&gt;" + Environment.NewLine) sb.Append("&lt;/x:WorksheetOptions&gt;" + Environment.NewLine) sb.Append("&lt;/x:ExcelWorksheet&gt;" + Environment.NewLine) sb.Append("&lt;/x:ExcelWorksheets&gt;" + Environment.NewLine) sb.Append("&lt;x:WindowHeight&gt;12780&lt;/x:WindowHeight&gt;" + Environment.NewLine) sb.Append("&lt;x:WindowWidth&gt;19035&lt;/x:WindowWidth&gt;" + Environment.NewLine) sb.Append("&lt;x:WindowTopX&gt;0&lt;/x:WindowTopX&gt;" + Environment.NewLine) sb.Append("&lt;x:WindowTopY&gt;15&lt;/x:WindowTopY&gt;" + Environment.NewLine) sb.Append("&lt;x:ProtectStructure&gt;False&lt;/x:ProtectStructure&gt;" + Environment.NewLine) sb.Append("&lt;x:ProtectWindows&gt;False&lt;/x:ProtectWindows&gt;" + Environment.NewLine) sb.Append("&lt;/x:ExcelWorkbook&gt;" + Environment.NewLine) sb.Append("&lt;/xml&gt;&lt;![endif]--&gt;" + Environment.NewLine) sb.Append("&lt;/head&gt;" + Environment.NewLine) sb.Append("&lt;body&gt;" + Environment.NewLine) Return sb.ToString() End Function </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
