Rafnas T P · Answer

no one will retrive password from database, this is a secured one,user has to enter that, thats why when you made textmode to password its not displaying, if you change this mode to text then it will show but it wont show as dots, I do not know why are you retriving password and showing to textbox, which is wrong

or you can just double click on the form now you can see form load event, inside that you can write as below textBox1.PasswordChar = '*'; instead of textBox1 you can give your textbox name

Thats not much likely if it is really a Windows Forms Application. This property is there, if i remember it rightly, ever since the first version of Visual Studio.

Krutika Karekar · Answer

Sir...I did not get property like PasswordChar....

Nitin Sontakke · Answer

If this is still not resolved, click on the text-box on the Windows Form, the press F4, which should open properties window. Locate PasswordChar property and type your preferred char (*, ., etc.) there. While you are there, I suggest you also set MaxLength property to an appropriate value.

Rafnas T P · Answer

if you are using sql then you can use nvarchar(50) as I have said before or you can use any string datatype
