Load Text Boxes dynamically

Hello, I am developing an online game panel.  As per screenshot there is  top menu with different values  and Middle menu with some values.

In top menu 0000-0999 is selected and in Middle menu 0000-0099 is selected and there are labels and text boxes from 0000 to 0099 - 100 boxes.

So when user will click on 0100-0199 menu from Middle menu it should show next 100 text boxes and labels with value 0100 to 0199.

Likewise if user selected 1000-1999 menu from Top menu the value of Middle menu will change and of all the  labels and text boxes.

I have to load these labels and boxes dynamically so that page will not take much time to load because if you calculate there are 10,000 labels and text boxes.

Can someone tell me how could I do this.?  Also when user click on any menu, labels and boxes will load but it should not refresh the page and I don't wish to use ASP.NET AJAX.

Page performance is very important for me.  I am loading these values from db.  I am using ASP.NET 4.0
