Typing in the Textbox

Question

I’m doing a project in the visual studio and I need help. I wonder if there is a way or how to make it so that when I type in the textbox,this I typed start at the front regardless of the position of the cursor or that it was sort of excluding until I got to the front. A textbox would be phone kind of like this:(__)____-____.

Answer 1

You can use the event Enter of MaskedTextBox that will be triggered whenever the user clicks on the component and inside it uses the method Select, in this way:

In the method below, it is also validated if the Textbox is empty to place the cursor at the beginning.

To use this way, you need to change the property TextMaskFormat for ExcludePromptAndLiterals. - This will make the property Text of TextBox contains only the text typed by the user.

private void maskedTextBox1_Enter(object sender, EventArgs e)
{
    var txtbox = (MaskedTextBox)sender;
    if (string.IsNullOrWhiteSpace(txtbox.Text))
    {
        this.BeginInvoke((MethodInvoker)(() => txtbox.Select(0, 0)));
    }
}
