It's ok to have questions but they have to be clear, and they need at least some effort to be shown.

try somethin like this.

before binding get distinct records from the table and bind it to gridview.

VB

cmbSectionName.DataSource=datatable1.AsEnumerable()
                           .Select(row => row.Field<string>("Section_Name"))
                           .Distinct()
                           .ToList();
cmbSectionName.DisplayMemberPath="Section_Name";
cmbSectionName.ValueMemberPath="Section_Name";

cmbSectionName.DataBind();
