ConditionalStyleCollection indexer (1 of 2)

Retrieves a ConditionalStyle object by conditional style type.

public ConditionalStyle this[ConditionalStyleType conditionalStyleType] { get; }

Examples

Shows how to work with certain area styles of a table.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

Table table = builder.StartTable();
builder.InsertCell();
builder.Write("Cell 1");
builder.InsertCell();
builder.Write("Cell 2");
builder.EndRow();
builder.InsertCell();
builder.Write("Cell 3");
builder.InsertCell();
builder.Write("Cell 4");
builder.EndTable();

// Create a custom table style.
TableStyle tableStyle = (TableStyle)doc.Styles.Add(StyleType.Table, "MyTableStyle1");

// Conditional styles are formatting changes that affect only some of the table's cells
// based on a predicate, such as the cells being in the last row.
// Below are three ways of accessing a table style's conditional styles from the "ConditionalStyles" collection.
// 1 -  By style type:
tableStyle.ConditionalStyles[ConditionalStyleType.FirstRow].Shading.BackgroundPatternColor = Color.AliceBlue;

// 2 -  By index:
tableStyle.ConditionalStyles[0].Borders.Color = Color.Black;
tableStyle.ConditionalStyles[0].Borders.LineStyle = LineStyle.DotDash;
Assert.AreEqual(ConditionalStyleType.FirstRow, tableStyle.ConditionalStyles[0].Type);

// 3 -  As a property:
tableStyle.ConditionalStyles.FirstRow.ParagraphFormat.Alignment = ParagraphAlignment.Center;

// Apply padding and text formatting to conditional styles.
tableStyle.ConditionalStyles.LastRow.BottomPadding = 10;
tableStyle.ConditionalStyles.LastRow.LeftPadding = 10;

table.Style = tableStyle;

// Our style applies some conditional styles by default.
Assert.AreEqual(TableStyleOptions.FirstRow | TableStyleOptions.FirstColumn | TableStyleOptions.RowBands,
