Set the value of an input tag with type="password" using C# and ASP.Net

Question

So I have this input tag:

<input type="password" id="password" name="password" runat="server" />

I'm trying to set its value using C# and ASP.Net before the page loads, but I can't get it to work.

Answer 1

Don't set the input type in your markup or ASP.NET will clear the input before it is rendered. Instead, use the following markup:

<input id="tbPassword" name="password" runat="server" />

...and the following code in your code-behind:

tbPassword.Value = "your password";
tbPassword.Attributes["type"] = "password";

However, I strongly advise against this approach. For one, you shouldn't be storing passwords in plain text. It's a really bad security practice.

Two, if you're just going to set the password in code, why require it at all? The point of a password input is for user interaction (entering a password). If you do that for them, then having it on the page is pointless.
