Forms Data Controls :: How To Change The Column Header From A DataSet

The following query returns me the column name from the table in the database, and stores the column name in the grid. How can I change the column name in the grid using following code, if its possible?

DataSet p_dsInformixDataDs = new DataSet();
string cmd = "SELECT * FROM CUSTOMERS";
try
{
using (IfxDataAdapter da = new IfxDataAdapter(cmd, m_InformixDBConn))
{
da.Fill(p_dsInformixDataDs);
}
}
DataView myDataView = new DataView(m_dsInformixDataDs.Tables[0]);
if (myDataView .Count > 0)
{
GridView1.DataSource = m_dsInformixDataDs;
GridView1.DataBind();
}
