Web Forms :: Disable Textbox Autofill - Automatically Displays CurrentUser

I've tried a few methods to get around this however none seem to work, whether its something to do with rendering or compiling Im not sure (both of which I have little knowledge in how they work). The problem is when the 'add new user' page is first loaded, the Page_load event gets the currentuser to ensure they are logged in and they have the correct authorisation. From this the textboxes where you would specify a new Username and Password are automatically populated with the current users details. I have not set anything to do so and in contrast Im tryin to get a way to stop it.

I've tried endless ways to get around it, things from jsut specifying the textboxes are empty or null to telling the textbox to remove all characters at character start int 0 (remove method). I'll give a few examples, they might not have been fully programmed write or maybe Im not utilising the methods as intended.


1. txtUsername.text = ""
2. txtUsername.text = null

3. if (txtUsername.Text == obj.Username || txtNewPassword.Text == obj.AdminPassword)
{
txtUsername.Text.Remove(0);
txtNewPassword.Text.Remove(0);
}
(tried && instead of || to)

4. if (txtUsername.Text == obj.Username || txtNewPassword.Text == obj.AdminPassword)
{
txtUsername.Text.Replace(Convert.ToChar(obj.Username), Convert.ToChar("Enter New Username"));
txtNewPassword.Text.Replace(Convert.ToChar(obj.AdminPassword), Convert.ToChar("Enter Password"));
}

5. if (txtUsername.Text == obj.Username.ToString() || txtNewPassword.Text == obj.AdminPassword.ToString() || txtUsername.Text != null && txtNewPassword.Text != null)
{
String.IsNullOrEmpty(txtUsername.Text);
String.IsNullOrEmpty(txtNewPassword.Text);
}

There are more, like if txtUsername visible then make the text = "" etc, so im thinking its probably something specific. Here is the page and script code below: .ASPX:
