I have a drop down list which gets its data from a database.

I want to add a label "select" which is not part of the data in the database.

Thanks.

What I have tried:

protected void Page_Load(object sender, EventArgs e)
        {       
          DDTitle.Items.Insert(0, new ListItem("Select Title", "0"));
          DDTitle.SelectedIndex = 0;



}

}

try like this

protected void Page_Load(object sender, EventArgs e)
      {
          if (!Page.IsPostBack)
          {

              DataTable dt = new DataTable();
              dt.Columns.Add("ValueColumn");
              dt.Columns.Add("TextColumn");
              dt.Rows.Add(1, "one");
              dt.Rows.Add(2, "two");
              dt.Rows.Add(3, "three");

              DDTitle.DataValueField = "ValueColumn";
              DDTitle.DataTextField = "TextColumn";
              DDTitle.DataSource = dt;
              DDTitle.DataBind();
              DDTitle.Items.Insert(0, new ListItem("Select Title", "0")); // this line should at the last
          }

      }

remove the hard coding and get the data from database.

Solution 2

<asp:DropDownList ID="DDTitle" runat="server"    DataTextField="Title" AutoPostBack="True" DataSourceID="SqlTitle" AppendDataBoundItems="true"></asp:DropDownList></td>

I had to set the AppendDataBoundItems=true.

thanks
