Is it possible to design such custom exception handling in ASP.NET webforms?

Then you need to increase this exception in your code appropriately Have Private: Zero login (string username, string password) {if (username! = Dbu name & password! = Db password) login details are incorrect ");} // Other Login ...} Private Zero Button (Object Sender, EventArgs E) {Log In (txtUsername.Text, txtPassword.Text);} Catch (LoginFileExchange Pre) {// Handle Exception}}
