Try this:

C#

//set below property via code or manually
//dgvHeader.AutoGenerateColumns = true;
//create datatable object
DataTable dt = new DataTable();
//add columns
dt.Columns.AddRange(new DataColumn[]
{
    new DataColumn("Column#1", typeof(string)),
    new DataColumn("Column#2", typeof(string))
});
//add rows
foreach (string item in getBaplieDetailsResult)
{
    string[] itemArray = item.Split('-');
    dt.Rows.Add(itemArray);
}
//bind ddata to datagridview
dgvHeader.DataSource = dt;
