About templates and data markers
An PowerPointWriter template is an PowerPoint presentation that contains PowerPointWriter data markers. A data marker is a line of text beginning with %%= that specifies a database column, variable, or array to insert into the presentation. PowerPointWriter supports data markers embedded in text. Data markers are added to a presentation in PowerPoint and then bound to data sources in code. PowerPointWriter populates the data markers with values from the data sources when the code is executed.
| Excerpt |
|---|
This tutorial demonstrates how to use data markers to import single and multiple rows of data, using the repeat slide marker, and removing slides. |
Data marker syntax
The basic syntax for a data marker is %%=[DataSourceName].[ColumnName], where DataSourceName is the name of the data source and ColumnName is the name of the column in the data source. You need to follow these rules when naming data markers:

Adding data markers to the the template
Our template consists of 5 slides populated with text and data markers.
...
In this section, we are only importing single rows of data. Importing multiple rows will be handled in part 2. The finished slide should look like the one below.
Adding a PowerPointWriter Reference in Visual Studio
| Info | ||
|---|---|---|
| ||
In the sample code, the reference to SoftArtisans.OfficeWriter.PowerPointWriter.dll has already been added to the ProjectProposal project. |
...
- Open Visual Studio and create a .NET project.
- The sample code uses a web application.
- Add a reference to SoftArtisans.OfficeWriter.PowerPointWriter.dll
- SoftArtisans.OfficeWriter.PowerPointWriter.dll is located under Program Files > SoftArtisans > OfficeWriter > dotnet > bin

PowerPointTemplate pptt = new PowerPointTemplate();
pptt.Open(Page.MapPath("//templates//part1_template.pptx"));
DataBindingProperties dataProps = pptt.CreateDataBindingProperties();
object[] valuesArray = { "Project Name", "Project Date", "Review", "Leader Name", "Start Date", "Cost Estimate", "Project Summary" };
string[] columnNamesArray = {"Name", "Date", "ReviewStatus", "Leader", "Start", "Estimate", "Summary"};
pptt.BindData(valuesArray, columnNamesArray, "Proposal", dataProps);
pptt.Process();
pptt.Save(Page.Response, "Part1_Output.xlsx", false)
