How can I make datagridView to display string instead of length.

Answer 1

It should be as simple as you say, you just have to make sure your datagridview has AutoGenerateColumns=true or you have the correct databound item inside the column block in the dataGridView on the form.

List<string> A = new List<string>(){"Apple","Banana","Pineapple"};
dataGridView.DataSource = A;
dataGridView.DataBind();
