Hi,
Place two dropdownlist boxes and a label in designer. Write the coding as shown below. Just you need to change the item from the ddlcompany and It will automatically calculated and show the output as you need.
<asp:DropDownList runat="server" ID="ddlCompany" AutoPostBack ="true" /><br />
<asp:DropDownList runat="server" ID="ddlProduct" AutoPostBack ="true" /><br />
<asp:Label ID="lbltest" runat="server" /><asp:DropDownList runat="server" ID="ddlCompany" AutoPostBack ="true" /><br />
<asp:DropDownList runat="server" ID="ddlProduct" AutoPostBack ="true" /><br />
<asp:Label ID="lbltest" runat="server" />Protected Sub ddlCompany_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlCompany.SelectedIndexChanged
If ddlCompany.SelectedIndex > 0 Then
lbltest.Text = ddlCompany.Items.Item(ddlCompany.SelectedIndex).Text & ","
lbltest.Text &= "Your price for a " & ddlProduct.Items.Item(ddlCompany.SelectedIndex).Text & "is "
lbltest.Text &= ddlProduct.Items.Item(ddlCompany.SelectedIndex).Value * (1 + ddlCompany.Items.Item(ddlCompany.SelectedIndex).Value)
ddlProduct.SelectedIndex = ddlCompany.SelectedIndex
Else
lbltest.Text = ""
End If
End SubProtected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack = False Then
ddlCompany.Items.Add(New ListItem("Please Select..."))
ddlCompany.Items.Add(New ListItem("ABC Company", "0.15"))
ddlCompany.Items.Add(New ListItem("XYZ Inc", "0.05"))
ddlCompany.Items.Add(New ListItem("Testing Corp", "0.20"))
ddlCompany.Items.Add(New ListItem("Retail Sales", "0.40"))
ddlProduct.Items.Add(New ListItem("Please Select..."))
ddlProduct.Items.Add(New ListItem("Skateboard", "250"))
ddlProduct.Items.Add(New ListItem("Surfboard", "598"))
ddlProduct.Items.Add(New ListItem("Wakeboard", "459"))
ddlProduct.Items.Add(New ListItem("Wake Skate", "125"))
End If
EndPlease execute it and you will get the idea about the DROPDOWNLIST control in asp.net

Just you need to group the items, Right!. Better you place more controls to differentiate them. For example:
Categories : load the group names into the categories DropDownlist
SubCategories (or) Items: load the items which is relevant to the category selecting above from dropdownlist at runtime.
Would you get me? and one more thing still i want to know exactly which control you are using?
I think you are in online, tell me asap
