I run the example, it display correctly, displaying three columns(Title, Page, Publisher). I have checked both Gridview Property and LINQ query, I didn't see anything related to specify those three columns. Where did you define it?

I try to follow the example, it display all rows, not just three column.

could you please explain me how to control gridview's column?

Thanks,

I found out that I need to set a property of GridView as below:

dataGridView1.AutoGenerateColumns = false;

I couldn't find it in the property window, but I can set it in the form load event.

Thanks,
