Here is the code with example.

Your .aspx code

<asp:DropDownList ID="drop1" runat="server">

<asp:ListItem Text="1" Value="1" />
<asp:ListItem Text="2" Value="2" />
<asp:ListItem Text="3" Value="3" />
</asp:DropDownList>

<asp:TextBox ID="txtText" runat="server" ></asp:TextBox>

<asp:Label ID="lblMessagE" runat="server"></asp:Label>
<asp:Button ID="btnSub" runat="server" Text="Submit" OnClick="SubmitMe" />


Code behind code

 protected void SubmitMe(object sender, EventArgs e)

{
int i = int.Parse(drop1.SelectedValue);
int j = int.Parse(txtText.Text);
int k = i * j;
lblMessagE.Text = k.ToString();
}


Above code should write multiplication result based on your selection in the label. You can also download the sample attached.
