Anchoring - Make two components take up half of panel each

I generally use a TableLayoutPanel to accomplish this. It is very easy to use (a simple introduction can be found here).

You create to cells in the first row and set it to 50% width each. In each cell you put one DataGrid and you set their Dock'ing to Fill.

Not sure if this is what you want:

1. Creating a SplitContainer on the screen.

   Anchor = Top, Bottom, Left, Right
   IsSplitterFixed = True (Trick)
   

2. Creating another two datagridviews, each a side inside the SplitterContainer

   Dock = Fill
