c# dataGridView null reference exception

Question

I'm using this code:

DataTable table = new DataTable();
table.Columns.Add("Title");
dataGridView1.DataSource = table;

to populate my dataGridView but I get a null reference exception when I set the datasource.

In your code only if dataGridView1 is null, such Exception will be thrown. Check that or give us more code.Notice that Exception always contains number of the line which thrown exception. — Fabio

Your dataGridView1 is most likely a NULL reference. To verify, set a breakpoint on the line and when you hit it, hover your mouse over dataGridView1.
