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?

Use Virtualization or MultiThreading. – rmojab63 Feb 14 '17 at 01:33 — rmojab63, Feb 14 '17 at 01:33

As Ramin commented in your answer, virtualization is the key to solve this. All your rows/columns are being loaded at the same time, right after entering the tab. The second answer you found is the one that probably will solve your issue. The first doesn't even seem related though. – r41n Feb 17 '17 at 09:55
