BreakForwardLink

Breaks the link to the next TextBox.

public void BreakForwardLink()

Remarks

BreakForwardLink doesn’t break all other links in the current sequence of shapes. For example: 1-2-3-4 sequence and BreakForwardLink at the 2-nd textbox will create two sequences 1-2, 3-4.

Examples

Shows how to link text boxes.

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

Shape textBoxShape1 = builder.InsertShape(ShapeType.TextBox, 100, 100);
TextBox textBox1 = textBoxShape1.TextBox;
builder.Writeln();

Shape textBoxShape2 = builder.InsertShape(ShapeType.TextBox, 100, 100);
TextBox textBox2 = textBoxShape2.TextBox;
builder.Writeln();

Shape textBoxShape3 = builder.InsertShape(ShapeType.TextBox, 100, 100);
TextBox textBox3 = textBoxShape3.TextBox;
builder.Writeln();

Shape textBoxShape4 = builder.InsertShape(ShapeType.TextBox, 100, 100);
TextBox textBox4 = textBoxShape4.TextBox;

// Create links between some of the text boxes.
if (textBox1.IsValidLinkTarget(textBox2))
    textBox1.Next = textBox2;

if (textBox2.IsValidLinkTarget(textBox3))
    textBox2.Next = textBox3;

// Only an empty text box may have a link.
Assert.True(textBox3.IsValidLinkTarget(textBox4));

builder.MoveTo(textBoxShape4.LastParagraph);
builder.Write("Hello world!");

Assert.False(textBox3.IsValidLinkTarget(textBox4));

if (textBox1.Next != null && textBox1.Previous == null)
    Console.WriteLine("This TextBox is the head of the sequence");

if (textBox2.Next != null && textBox2.Previous != null)
    Console.WriteLine("This TextBox is the middle of the sequence");

if (textBox3.Next == null && textBox3.Previous != null)
{
    Console.WriteLine("This TextBox is the tail of the sequence");

    // Break the forward link between textBox2 and textBox3, and then verify that they are no longer linked.
    textBox3.Previous.BreakForwardLink();

    Assert.IsTrue(textBox2.Next == null);
    Assert.IsTrue(textBox3.Previous == null);
}

doc.Save(ArtifactsDir + "Shape.CreateLinkBetweenTextBoxes.docx");
