Try this:

BoundField test = new BoundField();
test.DataField = "New DATAfield Name";
test.Headertext = "New Header";
CustomersGridView.Columns.Add(test);

@uuser3305953 - To use above code, you should first make autogeneratecolumns="false"

While this code snippet may solve the question, including an explanation really helps to improve the quality of your post. Remember that you are answering the question for readers in the future, and those people might not know the reasons for your code suggestion.

First set the property of your GridView yourGridView.AutoGenerateColumns = false then add following code to server side:

BoundField newColumn = new BoundField();

newColumn.DataField = "New DATAfield Name";
newColumn.HeaderText = "New Header";

yourGridView.Columns.Add(newColumn);

Note: Here newColumn is your Dynamic Column that you want to add, and yourGridView is your GridView name
