My question is for the two-way databinding to work, do I need: //pseudo code BindingSource.DataSource = IBindingList<Person> or can I do: BindingSource.DataSource =

问题 I have 10 records of data in a DataTable which has 3 fields "Foo", "Bar", and "Baz". If I connect wire this into a DataGridView I see 10 rows and 3 columns, and the column headers display the names of the fields.

I can do some things manualy, like overriding an OnPaint method and drawing the field names directly into

问题 How can I get DataGridView cell value to be written in the MessageBox in C#? 回答1: You can use the DataGridViewCell.Value Property to retrieve the value stored in a particular cell.
