Setting up the Template

About templates and data markers

A PowerPointWriter template is a 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.

Part 1 of this tutorial demonstrates how to use data markers to import single rows of data.
This tutorial demonstrates how to create a presentation for a proposal of a new software product.

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:

For more specific information about creating data markers, see How to use Data Markers

Adding data markers to the the template

The template for Part 1 consists of 2 slides populated with text and data markers.

In the downloadable PowerPointWriter_BasicTutorials.zip under ProjectProposal, there is a completed template file located in ProjectProposal/templates/part1_template.pptx.

1. Start with a blank .pptx file. Save the file as part1_template.pptx.

2. Set the presentation theme by going to the Design tab.

3. Add 3 text boxes to the first slide. These will hold our data markers for the title, date and review status of the proposed product. Populate the one you want to use as the title with the data marker %%=Proposal.Name. When the data is bound to the template, the name of the proposal will replace the data marker.

In the other two text boxes, add the %%=Proposal.Date, %%=Proposal.ReviewStatus data markers. The final slide should look something like the one below.

4. Add a new slide to the presentation. This slide should consist of two text boxes, one for the title and a large one for the body of text. In the title text box, place the data marker %%=Proposal.Name. Note that this is the same as the data marker used on our first slide, and will import the same data.

The rest of the slide will contain additional data about the proposal from the 'Proposal' data source. The data markers we are adding are: %%=Proposal.Leader, %%=Proposal.Start, %%=Proposal.Estimate, %%= Proposal.Summary and %%=Proposal.ReviewStatus.
PowerPointWriter supports data markers embedded in text, so only one text box is needed for all of our data markers.

The finished slide should look like the one below.

Adding a PowerPointWriter Reference in Visual Studio

In the sample code, the reference to SoftArtisans.OfficeWriter.PowerPointWriter.dll has already been added to the ProjectProposal project.

Create a .NET project and add a reference to the PowerPointWriter library.

  1. Open Visual Studio and create a .NET project.
  2. Add a reference to SoftArtisans.OfficeWriter.PowerPointWriter.dll

Writing the Code

There is a sample web application page Part1.aspx and code behind Part1.aspx.cs available in the ProjectProposal/templates/part1_template.pptx directory that shows the completed code.

1. Include the SoftArtisans.OfficeWriter.PowerPointWriter namespace in the code behind

using SoftArtisans.OfficeWriter.PowerPointWriter;

2. In the method that will actually create the presentation, instantiate the PowerPointTemplate object.

PowerPointTemplate pptt = new PowerPointTemplate();

3. Open the template file for the presentation.

pptt.Open(Page.MapPath("//templates//part1_template.pptx"));

4. Create a DatabindingProperties object for binding data to the template.

DataBindingProperties dataProps = pptt.CreateDataBindingProperties();

5. Create two arrays to hold the values for the presentation. The first is the array of values to add to the presentation. The second contains the column names. The column names values must match the data markers in the template.

//The values to display
 object[] valuesArray = { "Project Name", "Project Date", "Review", "Leader Name", "Start Date", "Cost Estimate", "Project Summary" };

//The column names are the same as the data markers
string[] columnNamesArray = {"Name", "Date", "ReviewStatus", "Leader", "Start", "Estimate", "Summary"};

6. Bind the data to the template. Make sure the data source name is the same as the name used in the template.

pptt.BindData(valuesArray, columnNamesArray, "Proposal", dataProps);

7. Call process to import the data into the template and save the file.

pptt.Process();

//Stream the output in the response as an attachment
pptt.Save(Page.Response, "Part1_Output.xlsx", false);

Final Code

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)
