'Declaration <LocalizabilityAttribute(LocalizationCategory.None, Modifiability := Modifiability.Unmodifiable)> _ Public Property MaxLength As Integer
Property ValueType: System.Int32
The maximum number of characters that can be manually entered into the text box. The default is 0, which indicates no limit.
You can use this property to restrict the length of text entered in the control for values such as postal codes and telephone numbers. You can also use this property to restrict the length of text entered when the data is to be stored in a database so that the text entered into the control does not exceed the maximum length of the corresponding field in the database.
This property does not affect characters that are added programmatically.
When this property is set to 0, the maximum length of the text that can be entered in the control is limited only by available memory.
The following example shows how to create a TextBox with a of 500 characters.
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <StackPanel> <TextBox Text="Initial text in TextBox" Width="200" TextAlignment="Center" TextWrapping="Wrap" MaxLength="500" MinLines="1" MaxLines="5" /> </StackPanel> </Page>
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 myStackPanel.Children.Add(myTextBox) Me.Content = myStackPanel
