testing the validity of a proposed value with a TextEdit's Mask property

Hi Michael,

You can create a default MaskManager that provides mask functionality according to the current mask type and verify whether the assigned value is valid (see the code below):

private void simpleButton1_Click(object sender, System.EventArgs e) {
    string testedText = "sample text";
    MaskManager mm = textEdit1.Properties.Mask.CreateDefaultMaskManager();
    mm.SetInitialEditText(testedText);
    if(testedText != mm.GetCurrentEditText() || !mm.IsMatch) {
        // Do some stuff.
        MessageBox.Show("Invalid value", "Error");
    }
    else {
        textEdit1.Text = testedText;
    }
}
