The C1MaskedTextBox.PromptChar property sets the characters that are used to prompt users in the C1MaskedTextBox control. By default the C1MaskedTextBox.PromptChar property is set to an underline character ("_") but you can customize this. For more details about the C1MaskedTextBox.PromptChar property, see Prompts.

At Design Time

To set the C1MaskedTextBox.PromptChar property, complete the following steps:

  1. Click the C1MaskedTextBox control once to select it.
  2. Navigate to the Properties tab and enter "0000" in the text box next to the C1MaskedTextBox.Mask property to set a mask.
  3. In the properties window, enter "#" (the pound character) in the text box next to the C1MaskedTextBox.PromptChar property

In XAML

To set the C1MaskedTextBox.PromptChar property add Mask="0000" PromptChar="#" to the <Xaml:C1MaskedTextBox> tag so that it appears similar to the following:

Markup
Copy Code
<Xaml:C1MaskedTextBox Height="23" Name="C1MaskedTextBox1" Width="120" Mask="0000" PromptChar="#"></Xaml:C1MaskedTextBox>

In Code

To set the C1MaskedTextBox.PromptChar property add the following code to your project:

Visual Basic
Copy Code
Dim x As Char = "#"c
C1MaskedTextBox1.Mask = "0000"
C1MaskedTextBox1.PromptChar = x

 

C#
Copy Code
char x = '#';
this.c1MaskedTextBox1.Mask = "0000";
this.c1MaskedTextBox1.PromptChar = x;

Run your project and observe:

The pound character will appear as the prompt in the control. In the following image, the number 32 was entered in the control:
