As a security measure , text inputted to a password textbox is cleared on post backs. If any of you come across a situation where it needs to be keep password visible on post backs, it would be not as straightforward as you might have think.
Achieving this objective involves following steps.
1. Textbox definition (in the .aspx page)
2. PageLoad code behind
txtAdminPWD.Attributes("type") = "password"
If ViewState("Password") IsNot Nothing Then
txtAdminPWD.Attributes.Add("value", ViewState("Password").ToString())
End If
3. Password stored to the textbox in the value and in view state (can be inside a method to populate the password )
ViewState("Password") = Decrypt(cUser.AdminPWD).ToString()
txtAdminPWD.Attributes.Add("value", Decrypt(cUser.AdminPWD).ToString())
4.Use the javascript PageLoad to restore password textbox value
function pageLoad() {
setTimeout(function () {
$("input#ctl00_cphMainContent_txtAdminPWD").val($("input#ctl00_cphMainContent_txtAdminPWD").val());
}, 10);
{
5. Clearing the password
txtAdminPWD.Text = ""
txtAdminPWD.Attributes.Add("value", txtAdminPWD.Text)
