Why is databinding so slow?

I am using databinding in my winforms project, but setting the DataSource property takes a few moments:

eventBindingSource.DataSource = _event;

I've tried setting the SuspendBinding() and ResumeBinding() methods, but this didn't make the binding faster.

Do you have any ideas to speed up the data binding?

Also when I edit a control, it goes very slow.

I am using Winforms, C# and the Entity Framework and _event is a POCO class with about 20 properties.

Turn of all auto sizing of DataGridView first, then set DataSource property, and set up your auto sizing preferences back. This really boost the power of DataGridView.

I suggest you install a profiler (there are free ones) and find out exactly what's taking the time. It will prevent any guesswork and you'll learn a lot about what is going on under the covers.

  • Paid: ANTS and dotTradre
  • Free: Equatec and SciTech

VS 2010 comes with one too if you have a high enough edition (can't remember which).
