Percentage in maskedTextBox display improperly

Question

I'm trying to display a percentages in a MaskedTextBox the string being passed in its "40.99" but when it displays on the form it is "409.9%".

populating value

 if (_person.Percentage != null)
    maskedTextBoxPercentage.Text = _person.Percentage.ToString();
 else
 {
    maskedTextBoxPercentage.Text = 0.00.ToString();
 }

maskedTextBoxPercentage properties

 this.maskedTextBoxPercentage.Location = new System.Drawing.Point(437, 125);
 this.maskedTextBoxPercentage.Mask = "000.00%";
 this.maskedTextBoxPercentage.Name = "maskedTextBoxPercentage";
 this.maskedTextBoxPercentage.Size = new System.Drawing.Size(129, 20);
 this.maskedTextBoxPercentage.TabIndex = 65;

enter image description here

@aliboy38 Right now i got it displaying correctly using "00.00%" as the mask , but it won't allow me to enter "100%" — Antarr Byrd, Aug 10 '12 at 20:23
@aliboy38 no error just ignore any input once it has four digits — Antarr Byrd, Aug 10 '12 at 20:28

If you expect it to display "40.99%", change your mask to "00.00%"

I tried that somewhat. Tried using "000.00%", since it can be 100% but now it displays "409.9_%" – Antarr Byrd Aug 10 '12 at 20:18

Try this :

try
            {
                this.maskedTextBoxPercentage.Mask = "00.00%";

            }
            catch (Exception)
            {
                this.maskedTextBoxPercentage.Mask = "000%";
            }

Or you can try this too :

try
        {
            this.maskedTextBoxPercentage.Mask = "00.00%";

        }
        catch (Exception)
        {
            this.maskedTextBoxPercentage.Text = "100%";
        }

This would be used at OnTextChanged ? – Antarr Byrd Aug 10 '12 at 20:34
I've never seen a try/catch used in InitializeComponent() – Antarr Byrd Aug 10 '12 at 20:46
i didn't know you used in InitializeComponent(). try TextChanged – Ali Vojdanian Aug 10 '12 at 20:55
It doesn't seem to have an effect. Responds just as it did before. – Antarr Byrd Aug 10 '12 at 20:56
