Question

I am trying to populate asp:DropDownList with data items and here is the code i have written so far

.aspx side

<asp:DropDownList ID="ddl" runat="server" />

C# side

protected void btnAdd_Click(object sender, EventArgs e)
{
  ddl.DataTextField = "hello";
  ddl.DataTextField = "2";
  ddl.DataBind();
}

The method btnAdd_Click is invoked. I tested it. But the data list is not getting populated with those data items.

Answer 1

Try adding your items like this

ddl.Items.Add(new ListItem("Your Text", "0"));
