Question

From MSDN entry for Control.ResetText():

Resets the Text property to its default value.

Stupid question, but I can’t find where I can set this “default value”. When I invoke ResetText() on TextBox all text is simply cleared.

Answer 1

The default value used by ResetText in the TextBoxcontrol is not configurable and it happens to be the string.Empty so that’s why when you invoke the method the text is cleared.

However, since the ResetText method is virtual you can do the following:

class MyTextBox : TextBox
{
    public override void ResetText()
    {
        this.Text = "MyDefaultText";
    }
}

Now, you just need to use your MyTextBox instead of the TextBox control. This is of course complicating things just for the sake of setting the Text property, so you are better of by assigning your default text directly to the Text property if you have no requirements to support a default value specifically through the use of ResetText.
