My application has several tabs (sections) and user is going to move between them . but them problem is that when I move between them, it appears slowly and part by part. actually it's not smooth.
for example in Reports tab , I have 2 forms that one of them is behind the another one, and when I click Report tab , the second one that is behind, loads for a moment. (that should not load at first)
before selecting the report tab :
report form selected and you can see the way of loading:
after a secound that loading completed :
and this is the form that is behind, I show it for you to see it . (by pressing a button in toolbar)
or for example in this picture, I'm going to change my tab to Graph
what is the best way to prevent this problem? I use WinForms C# .Net 4
