Setting up the Template

The template file should contain data markers following proper data marker syntax. Each copy of a given data marker will be populated with the same value. If the data marker appears in a table row or list entry, nothing will be automatically repeated if only one row is imported.

Binding Data

PowerPointTemplate has a single method for binding data to the data markers that are located in the template: {{[PowerPointTemplate.BindData]}}. Depending on the data source type and the number of rows in the data source, PowerPointWriter will either import a single row of data or [import multiple rows|Importing Multiple Rows of Data].

There are several ways to import a single row of data into a presentation:

1. Use a single dimensional array
2.  Use a multi-dimensional data source AND
   1. The data source only has one row of data
   2.  {{[DataBindingProperties.MaxRowsToImport]}} is set to 1

Single Dimensional Arrays

Arrays don't have built-in means to store column names. The user must specify the column names in a string array that is passed to {{PowerPointTemplate.BindData}} at run time.

Multi-dimensional data sources

If a multi-dimensional data source has only one row of data, the automatic repeating behavior will not occur. This is consistent for any of the multi-dimensional data sources supported by [BindData|PowerPointTemplate.BindData]:

•  Jagged and multi-dimensional arrays 
•  Custom objects (IEnumerable<T>) 
•  System.IDataReader and System.DataTable

Setting MaxRowsToImport to 1

MaxRowsToImport is a property on the [DataBindingProperties] object that can be used to limit the number of rows that are imported, regardless of how many rows are actually in the data source.
