Dear Friend's

I am facing one issue the scenario is as given below.

I have created an application which is has a master page, multiple pages map to that master page.
The master page has a menu control which is populated using data coming from Execute Procedure.
The menu map has child menu for each process.

But every time any page is accessed through menu, the page loads, as well as master page. This leads to the execution of the procedure and populate the menu control.

Is there any easy and perfect way to overcome this issue which effects the performance of the application.

Thanks in advance
