  • hi , i finally figured it out :
     
    SqlConnection conn = new SqlConnection("....");
    SqlDataAdapter Da = new SqlDataAdapter("GetEmp",conn);
    Dataset Ds= new DataSet();
    
    Da.Fill(Ds);
    
    combobox1.Datasource= Ds.Tables[0];
    combobox1.DisplayMember = "Title";
    combobox2.ValueMember="Title";
    
    label1.Text = combobox1.Selectedvalue.toString();
    but i still don't get why the Value Member is required the information are fetch from a Database why specify again the value member ?
