Hello ,

suppose you have one datagridview and there one comboboxcolumn named as
cmbproduct and if you want to bind the combobox value from dataset then

cmbproduct.DataSource = dsproduct.Tables[0].Columns[0].Table.DefaultView;
cmbproduct.ValueMember = "PId";
cmbproduct.DisplayMember = "Pname";

put this code where you want to load the combobox .

thanks
