Initialize TextBox with the Password TextMode

I'm trying to initialize the TextBox with the Password TextMode in 开发者_运维知识库my C# code. I do it in Page_Load function. But after the output in a browser there is no text.

this.passwordTextBox.Text = this.GetData().Password;
this.confirmPasswordTextBox.Text = this.GetData().Password;

How can I assing a value to this property?

You can set the password using:

this.passwordTextBox.Attributes["value"] = this.GetData().Password;

or

this.passwordTextBox.Attributes.Add("value", this.GetData().Password);
