2. We are going to bind a single string value to a slide in a template file. To do this, we will first need to add a data marker to the slide where we want the value to appear.

...

Below is a screenshot of the completed template file from the Hello World sample:

3. Now the template file is done. Next is writing the code to bind the string value to the data marker.

...

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

using SoftArtisans.OfficeWriter.PowerPointWriter;

2. Instantiate the PowerPointTemplate object.

PowerPointTemplate PPTT = new PowerPointTemplate();

3. Open the template file with PowerPointTemplate.Open.
The PowerPointTemplate object corresponds to a single template file, so a given PowerPointTemplate instance can only have one template file open.

PPTT.Open(Page.MapPath("templates\\Hello World.pptx"));

4. Create a DataBindingProperties object

DataBindingProperties DataProps = PPTT.CreateDataBindingProperties();

...

5. Get the data and create 2 arrays to hold the values and column names of the data you are importing.The column names should match the name of your data marker.

string value = DataValueBox.Text.Trim();
string[] values = { value };
string[] colNames = { "DataValue" };

6. Call PowerPointTemplate.BindData() to bind the data to the data marker. The data source name should match the value in your data marker.

PPTT.BindData(values, colnames, "DataSource1", DataProps);

...

7. Call PowerPointTemplate.Process() to insert the data into the file

PPTT.Process();

PowerPointTemplate.Process() handles everything relating to inserting the data into the file.

8. Save the output

PPTT.Save(Page.Response, "Output.pptx", false);

...

Congratulations, you have completed Hello World for PowerPointTemplate!

Final Code

using SoftArtisans.OfficeWriter.PowerPointWriter;
...
PowerPointTemplate PPTT = new PowerPointTemplate();
PPTT.Open(Page.MapPath("Hello World.pptx"));
DataBindingProperties DataProps = PPTT.CreateDataBindingProperties();
string value = DataValueBox.Text.Trim();
string[] values = { value };
string[] colNames = { "DataValue" };
PPTT.BindData(values, colNames, "DataSource1", DataProps);
PPTT.Process();
PPTT.Save(Page.Response, "Output.pptx", false);
