TextBox.MinLines Property

Gets or sets the minimum number of visible lines.

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

Public Property MinLines As Integer
<object MinLines="int" .../>

Property Value

Type: System.Int32
The minimum number of visible lines. The default is 1.

Identifier field


Metadata properties set to true



MinLines is greater than MaxLines.

Getting this property returns the current value of MinLines. Setting this property causes the text box to resize if the number of visible lines is less than value specified by MinLines.

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

The following example shows how to create a TextBox with a MinLines value of 1.

<Page  xmlns=""
      Text="Initial text in TextBox" 
      MaxLines="5" />

			Dim myStackPanel As New StackPanel()

			'Create TextBox
			Dim myTextBox As New TextBox()
			myTextBox.Width = 200

			' Put some initial text in the TextBox.
			myTextBox.Text = "Initial text in TextBox"

			' Set the maximum characters a user can manually type
			' into the TextBox.
			myTextBox.MaxLength = 500
			myTextBox.MinLines = 1

			' Set the maximum number of lines the TextBox will expand to 
			' accomidate text. Note: This does not constrain the amount of 
			' text that can be typed. To do that, use the MaxLength property.
			myTextBox.MaxLines = 5

			' The text typed into the box is aligned in the center.
			myTextBox.TextAlignment = TextAlignment.Center

			' When the text reaches the edge of the box, go to the next line.
			myTextBox.TextWrapping = TextWrapping.Wrap

			Me.Content = myStackPanel
