Null Password Char in Winform
c#, textbox, winforms
Solution
To reset `PassswordChar`, do this `txtPassword.PasswordChar = '\0';`
For your convenience:
private void checkBox1_CheckedChanged(object sender, EventArgs e){
txtPassword.PasswordChar = checkBox1.Checked ? '*' : '\0';
}
Problem
I have a `textbox` in a c# windows form i am having problems in assigning a null values to a `PasswordChar`. What i want to do is that if a `checkbox` is checked then the `PasswordChar` should be `null` i.e the actual text should be displayed else the `PasswordChar` should be `*`. This what i have tried ``` private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!checkBox1.Checked) { txtPassword.PasswordChar = '*'; } else { txtPassword.PasswordChar = ''; } } ``` but this line ``` txtPassword.PasswordChar = ''; ``` is generating an error. I have even tried ``` txtPassword.PasswordChar = null; ``` but i still get an error. Please help me correct my code.
