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. |
| Note |
|---|
Word WordWriter formulas are only supported with the Word 2007 OOXML file format (.docx/.docm). |
Code Sample: WordTemplate Formula Demo

This is an Enterprise Edition only feature. |
Placing Formulas in Merge Fields

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:

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

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