The Value property determines the currently visible text. By default the C1MaskedTextBox control starts with its Value not set but you can customize this at design time, in XAML, and in code.
To set the Value property add Value="123" to the <c1:C1MaskedTextBox> tag so that it appears similar to the following:
<c1:C1MaskedTextBox Height="23" HorizontalAlignment="Left" Margin="10,10,0,0" Name="C1MaskedTextBox1" VerticalAlignment="Top" Width="120" Value="123"></c1:C1MaskedTextBox>
To set the Value property add the following code to your project:
C1MaskedTextBox1.Value = "123"
c1MaskedTextBox1.Value = "123";
To set the Value property at run time, complete the following steps:
This will set the Value property to the number you chose.
