Export to Excel XLSX with Hyperlinks


Example RadGrid

Example Exported Excel (XLSX) File

When it comes to exporting HTML content to Excel, only the HTML-Based exporting supports it out of the box.

The built-in functionality to export to XLSX (OpenXML) will only export data, meaning that the content of Template Columns will not be included by default, see Export Template Columns.

This article will show how to Export Hyperlinks to XLSX (OpenXML) Excel using the Telerik Document Processing Libraries (DPL).


You will need to access the Excel Document Output generated by the Grid (see Generate Export Output), and using the APIs provided by the Telerik Document Processing Libraries (DPL), you can loop through the cells and rows of the Workbook and create Excel (XLSX) compatible Hyperlink for the affected cells.

RadGrid Markup Definition

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="true" AllowPaging="True" Width="400px" OnNeedDataSource="RadGrid1_NeedDataSource" OnItemCommand="RadGrid1_ItemCommand">
    <ExportSettings HideStructureColumns="true">
        <Excel Format="Xlsx" />
    <MasterTableView AutoGenerateColumns="False" DataKeyNames="Id" CommandItemDisplay="Top">
        <CommandItemSettings ShowExportToExcelButton="true" />
            <telerik:GridBoundColumn DataField="Id" UniqueName="Id" HeaderText="Id" ReadOnly="true"></telerik:GridBoundColumn>
            <telerik:GridTemplateColumn UniqueName="MyColumn" HeaderText="HyperLink">
                    <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("WebUrl") %>' Target="_blank" Text='<%# Eval("Name") %>'></asp:HyperLink>
            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="WebUrl" HeaderText="Web URL" UniqueName="WebUrl"></telerik:GridBoundColumn>

NeedDataSource Event

The event used to bind data to RadGrid

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    var listOfItems = new List<MyItem>();

    listOfItems.Add(new MyItem() { Id = 1, Name = "Progress", WebUrl = "" });
    listOfItems.Add(new MyItem() { Id = 2, Name = "Google", WebUrl = "" });
    listOfItems.Add(new MyItem() { Id = 3, Name = "Amazon", WebUrl = "" });

    (sender as RadGrid).DataSource = listOfItems;
public class MyItem
    public int Id { get; set; }
    public string Name { get; set; }
    public string WebUrl { get; set; }

using xlsx = Telerik.Windows.Documents.Spreadsheet.Model;

ItemCommand Event

This event is used to manipulate the export output

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    var grid = (RadGrid)sender;
    // If exporting to excel and the Excel Format is XLSX
    if (e.CommandName == RadGrid.ExportToExcelCommandName && grid.ExportSettings.Excel.Format == GridExcelExportFormat.Xlsx)
        // Cancel the original event.
        e.Canceled = true;

        // Generate a Workbook object with the Grid's structure
        xlsx.Workbook workbook = grid.MasterTableView.GenerateXlsxOutput<xlsx.Workbook>() as xlsx.Workbook;
        // Access the worksheet
        xlsx.Worksheet worksheet = workbook.Worksheets[0];
        // Access the used cells
        xlsx.CellRange usedCells = worksheet.UsedCellRange;
        // Number of columns used in the Worksheet
        int colCount = usedCells.ColumnCount;
        // Number of rows used in the Worksheet
        int rowCount = usedCells.RowCount;

        // If the CommandItem is displayed on the top
        if (grid.MasterTableView.CommandItemDisplay == GridCommandItemDisplay.Top || grid.MasterTableView.CommandItemDisplay == GridCommandItemDisplay.TopAndBottom)
            // Remove the first empty line from the Worksheet
            worksheet.Rows[0, 0].Remove();

        // If Filtering is enabled
        if (grid.MasterTableView.AllowFilteringByColumn)
            // Remove the Empty line below the Column Headers
            worksheet.Rows[1, 1].Remove();

        int rowOffset = 0;

        // If the header is shown, create an offset
        if (grid.ShowHeader)
            rowOffset += 1;

        // Get the Template Columns' Index/Position in RadGrid
        var colIndex = (grid.MasterTableView.GetColumn("MyColumn") as GridColumn).OrderIndex;

        // Discount the first two columns (GridExpandCollapseColumn & GridRowIndicatorColumn)
        colIndex -= 2; 

        // Loop through the Grid items
        for (int i = 0; i < grid.MasterTableView.Items.Count; i++)
            // Apply the Offset to exclude the Header row
            int affectedRowIndex = i + rowOffset;
            // Access the Grid item
            GridDataItem dataItem = grid.MasterTableView.Items[i];

            // Access the HyperLink control in the Grid row
            HyperLink myHyperLink = dataItem["MyColumn"].FindControl("HyperLink1") as HyperLink;

            // Select the Cell in Worksheet that will have a Hyperlink
            xlsx.CellSelection affectedCell = worksheet.Cells[affectedRowIndex, colIndex];
            // Create an Excel HyperLink based on the Hyperlink control from the Grid row
            xlsx.HyperlinkInfo webAddres = xlsx.HyperlinkInfo.CreateHyperlink(myHyperLink.NavigateUrl, myHyperLink.Text);
            // Add the Excel HyperLink to the selected Worksheet cell
            worksheet.Hyperlinks.Add(affectedCell.CellRanges.First(), webAddres);
            // Set the Selected Worksheet Cell's Text


        // Once done manipulating the Workbook, convert it to Byte array and download it
        // See "Helper Functions" section below for more info about the Download Function.
        DownloadXlsxFile(WorkbookToByteArray(workbook), grid.ExportSettings.FileName);
