Extracting information from a password text form in asp.net

Hey there, I'm having issues retrieving data from a password textbox. Here is my ASP code:

<asp:TextBox ID="txtConfirmPassword" TextMode="Password" runat="server"></asp:TextBox>

And here is my C# code on the server side:

NameValueCollection nvc = Request.Form;
 if (!string.IsNullOrEmpty(nvc["txtConfirmPassword"]))
{ string pass = nvc["txtConfirmPassword"].ToString(); }

But unfortunately, every time the result is nvc["txtConfirmPassword"] = null. I am unable to retrieve the password value in the code site. Can anyone please assist me with this issue?

Answer №1

To retrieve the value, you can simply utilize the ID of the control, like this:

let userPassword = txtConfirmPassword.Text;

There's a chance that the value may not show up in the form collection because of altered identifiers caused by containers, but I don't foresee any specific motive for trying to access it that way.

Answer №2

To retrieve the input text, you can utilize the .Text property.

string strConfirmPass = txtConfirmPassword.Text;

Answer №3

Due to security measures, passwords are not displayed in asp.net and cannot be retrieved after a postback.

To work around this limitation, you can add the password value to the control as an attribute. As the TextBox is rendered as an HTML input control, setting the value attribute is similar to setting the Text property.

  txtConfirmPassword.Attributes.Add("value", "yourRealPassword");

Use this method to set the value instead of using the Text property. You can still access the value through the Text property.

EDIT -

Based on feedback, I will update my answer for clarity. In ASP.NET, the Password TextBox loses its value after a postback. Here are some links supporting this claim:

ASP:TextBox Value disappears in postback only when password

Additionally, here is a resource explaining how to securely maintain a password field during a postback:

I hope this information proves helpful.
