Beginning in WordWriter version 4.1, WordTemplate now has the ability to evaluate a certain number


of formulas


 on data fields that are brought into a template.


WordWriter formulas are only supported with the Word 2007 OOXML file format (.docx/.docm). This is an Enterprise Edition only feature.


The following code opens the template and binds data to it using the SetDataSource and SetRepeatBlock methods, then streans the resulting document to the user:

Code Block

protected void OnDownload(object sender, EventArgs e)
     WordTemplate wt = new WordTemplate();

     string[] fields = new string[] { "TestDate", "School", "Town", "Version" };
     object[] values = new object[] { 
     new DateTime(2009, 11, 16).ToShortDateString(),
          "Samuel Adams HS", 
     wt.SetDataSource(values, fields, "");

     DataTable dt = GetScores();
     wt.SetRepeatBlock(dt, "Items");

     wt.Save(Response, "ScoreReport.docx", false);

private DataTable GetScores()
     DataTable dt = new DataTable();

     dt.Columns.Add("StudentID", typeof(string));
     dt.Columns.Add("ReadingScore", typeof(int));
     dt.Columns.Add("WritingScore", typeof(int));
     dt.Columns.Add("MathScore", typeof(int));
     dt.Columns.Add("TotalScore", typeof(int));

     Random rand = new Random();

     int rScore, wScore, mScore;
     for (int i = 0; i < 30; ++i)
          rScore = rand.Next(400, 800);
          wScore = rand.Next(400, 800);
          mScore = rand.Next(400, 800);
               string.Format("S{0:000000}", rand.NextDouble() * 1000000),
               rScore, wScore, mScore, rScore + wScore + mScore

     DataTable dtSorted = dt.Clone();
     foreach (DataRow row in dt.Select("", "StudentID asc"))

     return dtSorted;
