Namespace: Syncfusion.Pdf.Tables
Assembly: Syncfusion.Pdf.NET.dll
Syntax
public sealed class QueryRowCountEventHandler : MulticastDelegate
Examples
public string[][] datastring = new string[3][];
// Specify values for the table
datastring[0] = new string[] { "111", "Maxim", "100" };

datastring[2] = new string[] { "333", "Criss", "99" };
// Create a new document
PdfDocument document = new PdfDocument();
//Create a Page
PdfPage page = document.Pages.Add();
//Create the PdfLightTable
PdfLightTable pdfLightTable = new PdfLightTable();
// Setting the DataSourceType as Direct
pdfLightTable.DataSourceType = PdfLightTableDataSourceType.External;
//Subscribing Events
pdfLightTable.QueryRowCount += new QueryRowCountEventHandler(table_QueryRowCount);
pdfLightTable.QueryColumnCount += new QueryColumnCountEventHandler(table_QueryColumnCount);

//Draw PdfLightTable.
pdfLightTable.Draw(page, new PointF(0, 0));
//Save the document.
document.Save("Output.pdf");
//Close the document
document.Close(true);
