'System.Web.UI.WebControls.Panel' does not contain a definition for 'drpData'


i have the following problem:
Compiler Error Message: CS0117: 'System.Web.UI.WebControls.Panel' does not contain a definition for 'drpData'
Source Error:

Line 59: strvBilled = filepath.ToString();
Line 60: strvPris = tbvPris.Text;
Line 61: strvKategori = tbvKategori.drpData.SelectedItem.Value.ToString();
Line 62: strSQL = "INSERT INTO varelist (vNummer, vNavn, vBeskriv, vBilled, vPris, vKategori) Values (";
Line 63: strSQL += strvNummer + ", '";

It should come from this list:
<asp:panel ID="tbvKategori" runat="server"><asp:dropdownlist ID="drpData" DataTextField="kategoriNavn" DataValueField="kategoriId" Width="350px" runat="server"/></asp:panel>
Does anyone know what is the problem?

This error happened is due to 

1. A call was made to a method that does not exist for the data type.
2. This can also happen when a class name and its enclosing namespace name are the same and when a qualified method is called.
for i know, panel is no contain any method call "drpData"...
the correct way for writing this code should be :
dim strvKategori as string
dim myDrpBox as DropDownList
myDrpBox = tbvKategori.FindControl("drpData", DropDownList)
strvKategori = myDrpBox .SelectedItem.Value

i am trying to do this after 7 days of learning asp.net i our education. and we have this project we have to finish by monday, so i am running dry for braincells.

Therefor can i ask how it looks in C# which is the language we use in the programming.

emm... the code should look like as below:

string strvKategori;
DropDownList myDrpBox;
myDrpBox = (DropDownList) tbvKategori.FindControl("drpData");
strvKategori = myDrpBox.SelectedItem.Value.ToString();
lblResult.Text= strvKategori;
Hope you can solve it before the deal line.. happy programming!! :-)
