Textbox characters

Question

Hi I have a textbox where I will fill in a password (security is not important in this case). But I do want to display asteriks (*) when I fill in this textbox. I found a bunch of topics indicating that the textbox.passwordchar property should be changed but I'm not able to find that property... I noticed that there is a passwordbox control in VS2010 but it doesn't have the property pwbox.text or pwbox.content or anything like that... Any advice on this? Thanks in advance!

@ Murali: I adapted the datatype in my database and it works perfectly! Thank you very much!

@ Vulpes: That is indeed possible and graphically it is exactly what I need. The problem is that the value then no longer matches with the data I extracted from my database... Thanks for your input though!

I guess you could make a textbox into a password box with code such as this: private char[] password = new char[20]; // say private void textBox1_TextChanged(object sender TextChangedEventArgs e) { string text = textBox1.Text; for(int i = 0; i { if (text[i] != '*') password[i] = text[i]; } if (password.Length > text.Length) { for (int i = text.Length; i { password[i] = '\0'; } } textBox1.Text = new string('*' text.Length); textBox1.CaretIndex = text.Length; }

You need to do case sensitive comparision with LINQ to SQL queries. Please try the following. http://yourdotnetdesignteam.blogspot.com/2010/06/case-sensitive-linq-to-sql-queries.html Hope this helps you

That seems a little complicated for what I would like to do. I just want to display the filled in characters as asteriks... I also noticed that when filling in a password it is also accepted when putting it all in lowercase while on my sql server side it is clear that several characters are in uppercase. My code for the function behind the login: //Login Screen --> Click on Login private void btn_Login_Click(object sender RoutedEventArgs e) { VerifyLogin(tb_Username.Text tb_Password.Text); } //Method public bool VerifyLogin(string username string password) { //Connection to database DB_DataContext MyDataBase = new DB_DataContext(); var qry_LoginCredentials = from TblStaff in MyDataBase.TblStaffs where (TblStaff.Username == username.ToLower() && TblStaff.Password == password) select TblStaff; if (qry_LoginCredentials.Count() != 0) { return true; } MessageBox.Show(Username incorrect!); return false; }

There is in fact a dedicated PasswordBox control. Check out this MSDN link ( http://msdn.microsoft.com/en-us/library/system.windows.controls.passwordbox.passwordchar.aspx ) and this tutorial ( http://www.wpftutorial.net/PasswordBox.html ).
