Question

I have a listview. In my listview I have a dropdownbox which I want to fill in my codebehind page. Only the thing is, I don’t know how to access this webcontrol. The following doesn’t work:

DropDownList ddl = (DropDownList)lvUserOverview.Controls[0];

I know the index is 0 because the dropdownlist is the only control on the listview (also when I try index 1 I get a index out of range exception).

Can someone tell me how i can access the dropdownlist? In my pagebehind I want to add listitems.

ASPX Code :

<asp:DropDownList ID="ddlRole" onload="ddlRole_Load" runat="server">
</asp:DropDownList>

Codebehind:

protected void ddlRole_Load(object sender, EventArgs e)
{
  DropDownList ddl = (DropDownList)lvUserOverview.FindControl("ddlRole");
  if (ddl != null)
  {
      foreach (Role role in roles)
          ddl.Items.Add(new ListItem(role.Description, role.Id.ToString()));
  }
}

To get a handle to the drop down list inside of its own Load event handler, all you need to do is cast sender as a DropDownList.

DropDownList ddlRole = sender as DropDownList;
