I am developing a C# asp.net application. I have a webform which contains 2 dropdowns and a textbox with type="password". On "SelectedIndexChanged" event of the first dropdown, there is a postback, in order to fill the second dropdown according to the value selected in the first dropdown. The problem is that the password field which has been filled up before is cleared after postback. I know this is for security, but is there a way to keep the password??
