Public Sub SetRepeatBlock(ByVal jaggedArray As Object()(), ByVal columnNames As String(), ByVal bookmark As String)

Parameters

Param

	jaggedArray
	jaggedArray

An jagged array of objects to use as a data source. the first dimension corresponds to row and the second to column (that is, Object[row][column]). WordWriter will insert these values in the repeat block's merge fields.

Param

	columnNames
	columnNames

A string array of data source field names. These must be the same as the corresponding merge field names in the template.

Param

	bookmark
	bookmark

The bookmark name of the template repeat block. The bookmark passed to SetRepeatBlock must exist in the template Word file. To see a list of template bookmark names:

Open the template in Microsoft Word.
Open the Edit menu.
Select Go To...
Select Bookmark.
Under Enter bookmark name, open the drop-down list of bookmark names.

Remarks

A repeat block is a fragment in the template document that will be repeated for each row in a data source. In the template document, repeat blocks are defined by Word bookmarks that contain merge fields.

You can call SetRepeatBlock several times for a single instance of WordTemplate. The repeat block specified by the parameter bookmark must exist in the template.

If you pass an empty data source to SetRepeatBlock WordWriter will not include the specified repeat block in the generated Word file.
Not all Word features can be included in a repeat block:
