DataSource Null Pointer Exception

When I instantiate a new Windows Form with a DataGridView I always seem to get a Null Pointer exception when I try to set the data source like so:

dgvOpenRequests.DataSource = lstRequest

Normally this would be an obvious problem but its the DataSource that is the null pointer and not the list I am setting it as. And once the exception error has disappeared (We have customer error handling.) the program displays exactly as I would expect it to.

Setting the data source happens after:

InitializeComponent()

Consider writing the binding code in the Form_Load event. – NoChance Jan 06 '14 at 13:16
Please post more code. Reduce your problem into a separate project, where it does not reveal any of your production secrets and post it here. – Victor Zakharov Jan 06 '14 at 14:49
Please append all relevant code. As of now, your question is _impossible_ to answer. – Bjørn-Roger Kringsjå Jan 06 '14 at 16:18
