Working with Project Pages

Aspose.Tasks for .NET can retrieve the total number of pages in a project. The GetPageCount method offered by Aspose.Tasks.Visualization namespace returns the total page count in a project with options of rendering them based on Timescale.Days, Timescale.Months or Timescale.ThirdsOfMonths.

Get Number of Pages in Project

The Project class exposes the GetPageCount method.

You can specify different timescales:

• Timescale.Days – shows tasks/resources per day
• Timescale.Months – aggregates by months
• Timescale.ThirdsOfMonths – splits each month into three equal parts

To save a project to PDF:

1. Load a Microsoft Project file.
2. Get the project’s total page count using the GetPageCount method with optional timescale settings.

Programming Sample: Get Number of Pages in Project

The following lines of code shows how to achieve this using C#.

Project project = new Project("New Project.mpp");

// Get number of pages,  Timescale.Months, Timescale.ThirdsOfMonths
int iPages = project.GetPageCount();
iPages = project.GetPageCount(Timescale.Months);
iPages = project.GetPageCount(Timescale.ThirdsOfMonths);

Getting Number of Pages for Different Views

Aspose.Tasks for .NET supports rendering Resource Usage, Resource Sheet, and Task Usage views to PDF. You can also calculate the number of pages for each view separately. This programming sample demonstrates rendering a projects’ usage view and getting the number of pages in the rendered output.

Example: Get Page Count for Views (C#)

Project project = new Project("New Project.mpp");

// Get number of pages,  Months and  ThirdsOfMonths
Console.WriteLine(string.Format("Number of Pages = '{0}'", project.GetPageCount(PresentationFormat.ResourceUsage, Timescale.Days)));
Console.WriteLine(string.Format("Number of Pages = '{0}'", project.GetPageCount(PresentationFormat.ResourceUsage, Timescale.Months)));
Console.WriteLine(string.Format("Number of Pages = '{0}'", project.GetPageCount(PresentationFormat.ResourceUsage, Timescale.ThirdsOfMonths)));

Filtering Page Count by Date Range

If you need to calculate the number of pages for a specific date range (Start–End), Aspose.Tasks provides an overload of the GetPageCount method that accepts DateTime parameters.

Programming Sample: Get number of pages based on Start and End Dates

Project project = new Project("New Project.mpp");

ImageSaveOptions options = new ImageSaveOptions(SaveFileFormat.PNG)
{
    SaveToSeparateFiles = true,
    PageSize = PageSize.A3,
    Timescale = Timescale.Months,
    StartDate = project.Get(Prj.StartDate) - TimeSpan.FromDays(10),
    EndDate = project.Get(Prj.FinishDate) + TimeSpan.FromDays(30)
};
int pageCount = project.GetPageCount(
    PageSize.A3,
    Timescale.Months,
    project.Get(Prj.StartDate) - TimeSpan.FromDays(10),
    project.Get(Prj.FinishDate) + TimeSpan.FromDays(30));

Console.WriteLine(pageCount);
