ASP.NET - sub1(DropDownList1) call for: Public Shared Sub sub1(ByVal ddlControl As DropDownList)

re: Sorting a DropDownList using ArrayList

This is an excellent article. Thank you!

I am trying to figure out how to call the following sub in ASP.Net (VB) in Visual Studio 2010

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

   sub1(DropDownList1)

'Value of type 'System.Web.UI.WebControls.DropDownList' cannot be converted to 'WebApplication1.DropDownList'

End Sub

Public Shared Sub sub1(ByVal ddlControl As DropDownList)

Dim objListItem As ListItem = New ListItem("a".ToString(), "b".ToString())

    ddlControl.Items.Add(objListItem)

'Argument not specified for parameter 'value' of 'Public Sub Add(key As Object, value As Object)'.

End Sub

Can someone please help?

Looks like  you may have a custom class named DropDownList.  Perhaps you have a namespace WebApplication1 and you have a class called DropDownList?  For whatever reason, the compiler isn't sure which "DropDownList" class you are attempting to use.  The one if your WebApplication1 namespace or the one in System.Web.UI.WebControls.

If you fully qualify the class you are working with, you should be ok.

Public Shared Sub sub1(ByVal ddlControl As System.Web.UI.WebControls.DropDownList)
