You can try this:

<asp:DropDownList ID="DropDownList1" autopostback="true" runat="server">
<asp:ListItem Text="Lumber" value="~/ProductPage1.ascx" />
<asp:ListItem Text="Cutting Tools" value="~/ProductPage2.ascx" />
<asp:ListItem Text="Roofing Materials" value="~/ProductPage3.ascx" />
<asp:ListItem Text="Fencing" value="~/ProductPage4.ascx" />
</asp:DropDownList>

---

if(DropDownList1.SelectedItem.Text=="Lumber"){
Products1.visible = False
Dim featuredProductPath As String = DropDownList1.SelectedValue
Dim featuredProduct As Control = Page.LoadControl(featuredProductPath)
PlaceHolder1.Controls.Clear()
PlaceHolder1.Controls.Add(featuredProduct)
txtsmst.text="Lumber";
return;
}
ElseIf(DropDownList1.SelectedItem.Text=="Cutting Tools"){
Products1.Visible = False
Dim featuredProductPath As String = DropDownList1.SelectedValue
Dim featuredProduct As Control = Page.LoadControl(featuredProductPath)
PlaceHolder1.Controls.Clear()
PlaceHolder1.Controls.Add(featuredProduct)
txtsmst.text="Cutting Tools";
return;
}
ElseIf(DropDownList1.SelectedItem.Text=="Roofing Materials"){
Products1.Visible = False
Dim featuredProductPath As String = DropDownList1.SelectedValue
Dim featuredProduct As Control = Page.LoadControl(featuredProductPath)
PlaceHolder1.Controls.Clear()
PlaceHolder1.Controls.Add(featuredProduct)
txtsmst.text="Roofing Materials";
return;
}
ElseIf(DropDownList1.SelectedItem.Text=="Fencing"){
Products1.Visible = False
Dim featuredProductPath As String = DropDownList1.SelectedValue
Dim featuredProduct As Control = Page.LoadControl(featuredProductPath)
PlaceHolder1.Controls.Add(featuredProduct)
txtsmst.text="Fencing";
return;
}
End If
End Sub
