We have many forms each one with 5 Tabs. In each tabpage we have almost 150 ultrnumericeditors. The first time the form is loaded it needs more than 13 secs.  The second time more than 6. For exactly the same form one of our competitors use a Tab control from another vendor (Devexpress) that support lazy tab page loading (The controls in a TabPage  is initialized when the TabPage is selected, So it needs less than 1/5 of the time). Even with that our form (Only one tab) needs almost 1.2 secs (second call) to show up. If we change to microsoft controls it needs 0.35 secs. Is there any way to speed up the show up of that kind of forms?

Thank in advance
