Implementation of sharing a page with different asp.net Parameters

1. I thought of iframe. After using it, the problem is that the Add interface is also executed in iframe. This is useless.

2. Add the parameter Type in the address bar of the database configuration. The problem is that the left sidebar is not displayed when the parameter is added in the address bar of the database. You do not need to change the previous code.

3. initialize js load on the page. This can be implemented, but it is too slow and useless at last.

4. the user control, which is used at the end, defines the Type parameter in the user control background and gives the value on the interface used.
