Property Value

ScrollBars

One of the ScrollBars enumeration values that indicates whether a multiline TextBox control appears with no scroll bars, a horizontal scroll bar, a vertical scroll bar, or both. The default is ScrollBars.None.

Exceptions

InvalidEnumArgumentException

A value that is not within the range of valid values for the enumeration was assigned to the property.

Examples

The following code example creates a multiline TextBox control with vertical scroll bars. This example also uses the AcceptsTab, AcceptsReturn, and WordWrap properties to make the multiline TextBox control useful for creating text documents.

public:
   void CreateMyMultilineTextBox()
   {
      // Create an instance of a TextBox control.
      TextBox^ textBox1 = gcnew TextBox;
      
      // Set the Multiline property to true.
      textBox1->Multiline = true;
      // Add vertical scroll bars to the TextBox control.
      textBox1->ScrollBars = ScrollBars::Vertical;
      // Allow the TAB key to be entered in the TextBox control.
      textBox1->AcceptsReturn = true;
      // Allow the TAB key to be entered in the TextBox control.
      textBox1->AcceptsTab = true;
      // Set WordWrap to true to allow text to wrap to the next line.
      textBox1->WordWrap = true;
      // Set the default text of the control.
      textBox1->Text = "Welcome!";
   }

public void CreateMyMultilineTextBox()
{
    // Create an instance of a TextBox control.
    TextBox textBox1 = new TextBox();
    
    // Set the Multiline property to true.
    textBox1.Multiline = true;
    // Add vertical scroll bars to the TextBox control.
    textBox1.ScrollBars = ScrollBars.Vertical;
    // Allow the TAB key to be entered in the TextBox control.
    textBox1.AcceptsReturn = true;
    // Allow the TAB key to be entered in the TextBox control.
    textBox1.AcceptsTab = true;
    // Set WordWrap to true to allow text to wrap to the next line.
    textBox1.WordWrap = true;
    // Set the default text of the control.
    textBox1.Text = "Welcome!";
 }

Public Sub CreateMyMultilineTextBox()
    ' Create an instance of a TextBox control.
    Dim textBox1 As New TextBox()
    
    ' Set the Multiline property to true.
    textBox1.Multiline = True
    ' Add vertical scroll bars to the TextBox control.
    textBox1.ScrollBars = ScrollBars.Vertical
    ' Allow the TAB key to be entered in the TextBox control.
    textBox1.AcceptsReturn = True
    ' Allow the TAB key to be entered in the TextBox control.
    textBox1.AcceptsTab = True
    ' Set WordWrap to true to allow text to wrap to the next line.
    textBox1.WordWrap = True
    ' Set the default text of the control.
    textBox1.Text = "Welcome!"
End Sub

Remarks

Horizontal scroll bars will not be shown if the WordWrap property is set to true, regardless of the value of the ScrollBars property.
