Hi there,

I have a page to add new customer details with some textboxes to enter the data.
When I click addnew customer link it will be redirected to the "AddNewCustomerPage.aspx".

In another page I have a list of customers.
When I click a row and press edit button it should be redirected to the same "AddNewCustomerPage.aspx" file, with all the textboxes filled with the clicked user data, and there it is possible to change the textbox values and edit data.

My doubt is how to acknowldege the "AddNewCustomerPage.aspx" page with the status of the mode.

To add new customer details it should be in new mode with all textboxes empty in order to add new data, but if it is in edit mode the boxes will have corresponding user data.

I used QueryString values to differenciate "NEW" and "EDIT" mode.
Is there any other flexible method to do this other than "Querystring"?

Here the customer Id is the primary key so it is not possible to pass through the query string.

Thank You in advance

A better way would be to implement as follows:

Accept a QueryString parameter "CustomerId" in AddNewCustomerPage.aspx.cs. If the parameter value (CustomerId) is greater than 0, retrieve the Customer from the database using the CustomerId and set the customer properties in the text boxes. Otherwise, just show the text boxes.

You don't need to use the "NEW" or "EDIT" mode.

That is, you just implement the following logic in the Page_Load of AddNewCustomerPage.aspx.cs

int CustomerId = 0;
if(Request.Params["CustomerId"] != null)
{
    CustomerId = Convert.ToInt32(Request.Params["CustomerId"]);
}
if(CustomerId > 0)
{
    Customer customer = GetCustomerFromDB(CustomerId)
    PopulateUI(customer);
}
