c# WinForms can you get the NumericUpDown text area

Question

Is it possible to get the text area of a NumericUpDown control? I\'m looking to get it\'s size so that I can mask it with a panel. I don\'t want the user to be able to edit

Answer 1

You can get this by using a Label control instead of the baked-in TextBox control. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.

using System;
using System.Windows.Forms;

class UpDownLabel : NumericUpDown {
    private Label mLabel;
    private TextBox mBox;

    public UpDownLabel() {
        mBox = this.Controls[1] as TextBox;
        mBox.Enabled = false;
        mLabel = new Label();
        mLabel.Location = mBox.Location;
        mLabel.Size = mBox.Size;
        this.Controls.Add(mLabel);
        mLabel.BringToFront();
    }

    protected override void UpdateEditText() {
        base.UpdateEditText();
        if (mLabel != null) mLabel.Text = mBox.Text;
    }
}
