How to determine the number of pages in a report.

Hey David,

I think you may be experiencing unintended behavior.

I add new pages in a slightly different manner than yours:

theSection.AddPage().AddText(50f, 50f).AddContent("This page intentionally left blank #1");

I do this rather than adding a page break however, both should work similarly.

I notice that whenever I call theReport.Generate( ), anything I add afterwards is not added. It seems that something internal to the Report is causing anything that is added after the Generate( ) method to not be added.

At this point there are 2 things you can do:

1: If you need to make this work right away without any delay, you will have to execute your logic 2 times: First to determine your page count and then a second time to use the page count (without calling Report.Generate() ) to perform your page adding logic.

2: Submit a bug to Developer Support. Use the following code to create a sample based on your particular assembly build:

Create a Web Project and add a WebGrid that is bound to some dummy data. Add a button and handle its Click event handler. Put this code in the Page to make it all work:

protected void Button1_Click(

object sender,

EventArgs e)

{

this.CreateReport(this.UltraWebGrid1, this.Response, false);

}

/// <summary>

/// Creates a PDF Document by walking a flat WebGrid

/// </summary>

/// <param name="theGrid">This is the Grid that will be walked</param>

/// <param name="theResponse"> This is the current HTTP Response object that will receive the PDF</param>

/// <param name="openInline">Option to show the PDF within the Browser itself OR to present it as a download prompt. </param>

public void CreateReport(

UltraWebGrid theGrid,

HttpResponse theResponse, bool openInline)

{

Report theReport = new Report();

ISection theSection = theReport.AddSection();

//Table Pattern (think of this as a kind of "Style Sheet" for ITable

TablePattern theTablePattern = new TablePattern();

theTablePattern.Header.Repeat = true;

theTablePattern.Header.Cell.Background = new Background(Infragistics.Documents.Graphics.Brushes.Red);

theTablePattern.Row.Cell.Background = new Background(Infragistics.Documents.Graphics.Brushes.LemonChiffon);

ITable theTable = theSection.AddTable();theSection.PageMargins = new Margins(20f);

theTable.ApplyPattern(theTablePattern);

ITableCell theHeaderCell = null;

IText theHeaderText = null;

//Iterate through the Grid Cols and create corresponding headers in the ITable

foreach (UltraGridColumn c in theGrid.Columns)

{

theHeaderCell = theTable.Header.AddCell();

theHeaderText = theHeaderCell.AddText();

theHeaderText.Style.Brush = new Infragistics.Documents.Graphics.SolidColorBrush(Infragistics.Documents.Graphics.Colors.WhiteSmoke);

theHeaderText.AddContent(c.Header.Caption);

}

ITableRow theRow = null;

ITableCell theRowCell = null;

IText theRowText = null;

//Now create your rows:

foreach (UltraGridRow r in theGrid.Rows)

{

theRow = theTable.AddRow();

foreach (UltraGridColumn c in this.UltraWebGrid1.Columns)

{

theRowCell = theRow.AddCell();

theRowText = theRowCell.AddText();

theRowText.Style.Brush = new Infragistics.Documents.Graphics.SolidColorBrush(Infragistics.Documents.Graphics.Colors.Black);

theRowText.AddContent(r.Cells.FromKey(c.Key).Value.ToString());

}

int thePageCount = 0;

//UNCOMMENT THIS LINE AND THE PAGES AND IMAGE THAT ARE ADDED AFTER THIS LINE

//DO NOT SHOW UP IN THE GENERATED REPORT: TomP

//thePageCount = theReport.Generate().Count; //1;

if (thePageCount % 2 != 0)

{

theSection.AddPage().AddText(50f, 50f).AddContent("This page intentionally left blank #1");

}

else

{

theSection.AddPage().AddText(50f, 50f).AddContent("This page intentionally left blank #2");theSection.AddPage().AddText(50f, 50f).AddContent("This page intentionally left blank #3");

}

//add an image:

theSection = theReport.AddSection();

theSection.AddText().AddContent(this.GetImage(@"http://www.infragistics.com/App_Themes/Default/images/logo.gif"));

//Set up the response for publishing the Report:

theResponse.ContentType = "application/pdf";if (openInline)

{

//Opens in Browser Itself.

theResponse.AddHeader("content-disposition", "inline; filename=Document.pdf");

}

else

{

//Prompts user for a file download.

theResponse.AddHeader("content-disposition", "attachment; filename=Document.pdf");

}

//Write out to the response.Output Stream and you are done.

theReport.Publish(theResponse.OutputStream, FileFormat.PDF);

}

/// <summary>

/// This method returns an Infragistics

/// Image object that represents the

/// Image that exists at an accessible URL

/// </summary>

/// <param name="theImageURL">

/// This is the URL to your image.

/// E.G.

/// http://www.infragistics.com/App_Themes/Default/images/logo.gif</param>

/// <returns>The Infragistics.Documents.Graphics.Image object that is used in your Report</returns>

public Infragistics.Documents.Graphics.Image GetImage(string theImageURL)

{

System.Drawing.Image theImage = null;

WebRequest theRequest = WebRequest.Create(theImageURL);

WebResponse theResponse = theRequest.GetResponse();

theImage = System.Drawing.Image.FromStream(theResponse.GetResponseStream());

theResponse.Close();

theResponse = null;

theRequest = null;

return new Infragistics.Documents.Graphics.Image(theImage);

}

Now David, when you put together your sample for Developer Support, be aware of the code comment I placed in my CreateReport( ) method. If you run the sample without calling the Report.Generate( ) then the resulting PDF is going to have the Rows of data, a blank page and then the Infragistics image on the last page.

If you uncomment the line where it says so, it WILL call the Report.Generate( ) method and therefore cause anything else added to the report (the blank pages and image) to not be included in the PUBLISHED report.

If this is indeed a bug, it will be checked out by a developer and the bug will be associated with your incident and therefore be expedited as quickly as possible. This is why I am asking you to submit the support incident, so that you get the quickest response.

Thanks,

Tom
