In your code, the try and catch blocks are correctly set up to catch exceptions that might occur within the try block. However, based on your requirement, it seems like you want to handle exceptions only when there's an error or issue with the code inside the try block. If you don't want to catch exceptions for business logic conditions like incorrect login credentials, you should modify your code as follows: protected void btnSubmit_Click(object sender, EventArgs e) { try { if (txtName.Text == "Jaya" && txtPwd.Text == "1234") { Server.Transfer("Retailer.aspx"); } else { // This is where you handle the case of incorrect login credentials // You don't need to catch an exception for this; instead, you can display a message to the user or log it as needed. ShowErrorMessage("Incorrect login credentials. Please try again."); } } catch (Exception ex) { // Handle any unexpected exceptions here oExceptionManager.LogError(ex.Message, "Error From btnSubmit_Click in Login.aspx.cs"); } } In the modified code, I've removed the catch block around the entire try block. Instead, I added a custom method ShowErrorMessage to handle the case of incorrect login credentials within the else block. This way, exceptions will only be caught and logged for unexpected issues, and you can handle business logic issues separately. Thanks Naimish Makwana
