Conditional table column type creation, base on DataSource Field

[molaie]

creating table column type (or value) base on some condition on DatSource

And it is not a calculated field.
Say, for example in PdfReportSamples.Models, UserMonthCalendar, i have this new field:

 public class UserMonthCalendar {
    public int Id { set; get; }
    public string Name { set; get; }
    //new field added
    public bool Nodata { set; get; }
    public CalendarData MonthCalendarData { set; get; }
}

then i want to be able to do something like :

            columns.AddColumn(column => {
               if ( (bool)list.GetValueOf<UserMonthCalendar>(x => x.Nodata)) {
                    column.PropertyName<UserMonthCalendar>(x => x.Name);
                    column.CellsHorizontalAlignment(HorizontalAlignment.Center);
                    column.IsVisible(true);
                    column.Order(2);
                    column.Width(1);
                    column.HeaderCell("نام");
                } else {
			column.PropertyName<UserMonthCalendar>(x => x.MonthCalendarData);
			column.CellsHorizontalAlignment(HorizontalAlignment.Center);
			column.IsVisible(true);
			column.Order(3);
			column.Width(3);
			column.HeaderCell("تقويم ماهيانه");
			column.ColumnItemsTemplate(itemsTemplate =>
			{
				itemsTemplate.MonthCalendar(new CalendarAttributes
				{
					CalendarType = CalendarType.PersianCalendar,
					UseLongDayNamesOfWeek = true,
					Padding = 3,
					DescriptionHorizontalAlignment = HorizontalAlignment.Center,
					SplitRows = true,
					CellsCustomizer = info =>
					{
						if (info.Year == 1391 && info.Month == 1 && info.DayNumber == 1)
						{
							info.NumberCell.BackgroundColor = new BaseColor(System.Drawing.Color.LimeGreen.ToArgb());
							var phrase = info.NumberCell.Phrase;
							foreach (var chunk in phrase.Chunks)
								chunk.Font.Color = new BaseColor(System.Drawing.Color.Yellow.ToArgb());
						}
					}
				});
			});
                }

            });

but list is avaiable only in CalculatedField, and here the column is not a CalculatedField but a ConditionalColumn

Also, many thanks for your great work.

i'm going to generate something like attached picture. obviously, this is Html, and i need to export it.
Be careful that row 1 has just a simple value from datasource, and second row, is a full table, with same instance of Datasource.

Move your datasource

 var listOfRows = PersianMonthCalendarDataSource.CreateDataSource();

before

return new PdfReport().DocumentPreferences

Now you can access listOfRows everywhere.

[molaie]

It is not about accessing listOfRows anywhere, i already pass datasource as input parameter to function.
I need to access current row index, to get some value of it, and then base on on some filed value, have 2 type of column rendering.
is there any way to do that?

[VahidN]

You can't do that. columns.AddColumn is a one time action. It's a definition of the structure of the table. you can't change it for the row n.

[molaie]

thanks for your patience, and how to create something like i want in picture that i have attached? (or any link to a sample on itextsharp).
it is really a nested table.

[VahidN]

Custom table cells are supported by PDFReport. Here you can return whatever you want as a pdfCell based on the attributes.RowData.TableRowData. It can be an HTML cell too. Also it can be defined as an inline custom cell provider.

[molaie]

And not related to main question, but how to hide table header row?
as in attached image(in second comment), i don't need to show any cell header.

[VahidN]

Set ShowHeaderRow to false
