Pre-load WPF DataGrid

Question

My DataGrid(In a tab) has a lot of ColumnHeader and DataTrigger. Everything is good until I select the tab for the first time, whole application lag for 5 seconds. After that, there is no more lag.

So I was wondering if I can pre-load DataGrid first, then there won't be a lag. Is it possible to do so?
