Word-Docx (OOXML) Export

DOCX is a well-known format for Microsoft Word documents introduced with the release of Microsoft Office 2007, the structure of this new Document format was changed from plain binary to a combination of XML and binary files. Docx files can be opened with Word 2007 and lateral versions but not with the earlier versions of MS Word which support DOC file extensions.

This format accommodates the Office Open XML (OOXML). Documents under this Standard were given .docx extension, the “X” being for XML.

Telerik ASP.NET AJAX Controls support this format since Q3 2014 by utilizing the Telerik Document Processing Libraries (DPL).

The DPL is included in the Telerik UI for ASP.NET AJAX suite, see Included Assemblies .

In order to use this export format, be sure to reference the DPL assemblies and change the <ExportSettings-Excel-Format> property to Docx.


<telerik:RadGrid ID="RadGrid1" runat="server">
        <Excel Format="Docx" />

Requires Assemblies

The assemblies that must be referenced in order to export RadGrid to Word are:

  • Telerik.Windows.Documents.Core.dll
  • Telerik.Windows.Documents.Flow.dll
  • Telerik.Windows.Zip.dll

Export Events

Customizing the Export Output

Data Formatting

When you set DataFormatString of RadGrid columns, the format will be applied to the exported file. Note that only the custom numeric format strings (Example 1)will work because in most scenarios they match the Microsoft Excel's custom numeric format. The built-in .NET standard numeric format strings (Example 2) can still be used, but the output will not be as expected. It is important to note, that the exported file is based on the actual RadGrid cells values. When DataFormatString is applied, these values will already be formatted which could be prevented by setting the SuppressColumnDataFormatStrings property to true.

Example 1

<telerik:GridBoundColumn DataType="System.DateTime" DataField="DateField" DataFormatString="{0:tt dd-MM(yyyy) }" />

Example 2

<telerik:GridBoundColumn DataType="System.Double" DataField="DoubleField" DataFormatString="{0:C2}" />

Hiding Columns / Rows

Hiding rows and columns is pretty straightforward. Actually you can hide these elements in the same way you hide them in a normal server-side scenario.

RadGrid1.MasterTableView.GetColumn("Col1").Visible = false;
RadGrid1.MasterTableView.Items[1].Visible = false; //when IgnorePaging is false
RadGrid1.MasterTableView.GetColumn("Col1").Visible = False
RadGrid1.MasterTableView.Items(1).Visible = False 'when IgnorePaging is false

Additionally you could use the Exportable property that allows you to choose whether a certain column should be included in the exported file or not. By setting this property to false the related column will be excluded from the exported file.Its default value is true.

Styling Columns / Rows / Cell

In order to style the elements of the RadGrid you could use the standard ASP.NET style properties such as ItemStyle,AlternatingItemStyle, HeaderStyle and FooterStyle to provide a custom style for the items of RadGrid control.

<AlternatingItemStyle BorderColor="Red" BorderStyle="Solid" BorderWidth="1px" />
<ItemStyle ForeColor="Green" />
<HeaderStyle BackColor="Yellow" />

Another approach is to hook OnInfrastructureExporting event handler and apply the styles in code behind. Note that styling via CSS classes is not possible.

Styling Columns

xls.Column col = e.ExportStructure.Tables[0].Columns[2];
col.Style.BackColor = Color.Gray;
col.Style.ForeColor = Color.Yellow;
Dim col As xls.Column = e.ExportStructure.Tables(0).Columns(2)
col.Style.BackColor = Color.Gray
col.Style.ForeColor = Color.Yellow

Styling Rows

xls.Row row = e.ExportStructure.Tables[0].Rows[2];
row.Style.BackColor = Color.Blue;
Dim row As xls.Row = e.ExportStructure.Tables(0).Rows(2)
row.Style.BackColor = Color.Blue

Styling Cells 1

xls.Cell cell1 = e.ExportStructure.Tables[0].Cells["B2"];
cell1.Style.BackColor = Color.Yellow;
Dim cell1 As xls.Cell = e.ExportStructure.Tables(0).Cells("B2")
cell1.Style.BackColor = Color.Yellow

Styling Cells 2

xls.Cell cell2 = e.ExportStructure.Tables[0].Cells[3, 3];
cell2.Style.ForeColor = Color.Tomato;
Dim cell2 As xls.Cell = e.ExportStructure.Tables(0).Cells(3, 3)
cell2.Style.ForeColor = Color.Tomato

Default Cell Alignment

You can specify a default alignment to all cells by using DefaultCellAlignment. This property is supported since Q2 2015 and its default value is NotSet. Typical values include Left, Right and Center.

    <Excel DefaultCellAlignment="Center" />

Additionally you can change the default alignment on OnInfrastructureExporting event.

Image Support

This format supports exporting of images. The images are included automatically in the exported document and you do not have to set any specific property. Keep in mind images with an absolute or relative path are supported, but binary images are not.


Exporting the following features are not supported

  • Hierarchy
  • Binary Images
  • Automatic column/row resizing
  • Custom skins whose images are set via the ImagesPath property instead of referenced in the stylesheet.
