Population of ComboBox with DisplayMember and ValueMember

问题

I am trying to populate Combox like this :

        DataSet ds = new DataSet();
        SqlDataAdapter da = new SqlDataAdapter("SELECT id,name FROM table1", con);
        da.Fill(ds, "FillDropDown");

        comboProject.DisplayMember = "FillDropDown.name";
        comboProject.ValueMember = "FillDropDown.id";
        comboProject.DataSource = ds.Tables["FillDropDown"];

But all item are showing as "System.Data.DataRowView" in Combobox. why it is like that? Thanks in Advance.

回答1:

try  comboProject.DataSource = ds.Tables["FillDropDown"].DefaultView;

回答2:

try this:

DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter("SELECT id,name FROM table1", con);
da.Fill(ds, "FillDropDown");

comboProject.DisplayMember = "name";
comboProject.ValueMember = "id";
comboProject.DataSource = ds.Tables["FillDropDown"];
comboProject.DataBind();
