How can i improve my page loading

I would suggest you to use Page inheritance. You can achive it in this fashion.

1. First you create a Base page which is inherited from the System.Web.UI.Page class.

public class BasePage : System.Web.UI.Page
{
    // ...Add Header and Footer Information here or any other information.

    protected override void OnLoad(EventArgs e)
     {
       // ... add custom logic here ...
      
       // Be sure to call the base class's OnLoad method!
       base.OnLoad(e);
    }

    // ... You can
   
}

2. Then you create your all other page inherited from this BasePage.

public class CustomPage : BasePage // changed ": System.Web.UI.Page"
{
    // ...
}


Base Pages are executed faster then User Controls.
