MaxLines Property

TextBox.MaxLines Property


Gets or sets the maximum number of visible lines.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public int MaxLines { get; set; }

Property Value

Type: System.Int32

The maximum number of visible lines. The default is Int32.MaxValue.

Exception Condition

MaxLines is less than MinLines.

Getting this property returns the current value of MaxLines. Setting this property causes the text box to resize if the number of visible lines exceeds the limit specified by MaxLines.

This property applies only to visible lines, and does not constrain the actual number of lines. Depending on its configuration, a text box may contain additional non-visible lines that are accessible by scrolling.

If the Height property is explicitly set on a TextBox, the MaxLines and MinLines property values are ignored.

Identifier field


Metadata properties set to true
