C#2010 Calculation question
C#2010 Calculation question
- Hi all :) fairly new to C# (Previously used Java before.. but learning as I go along lol)
So using VS2010 and working within ASP.NET as a web page format... but that's not really related.
My question is... if I have a dropdownlist of possible selections.. how would I make a calculation from a given answer?
For example, if someone was to select a given service from 4 possible options and I wanted to calculate the price, how would this be done?
<p class="style3">
Service
<asp:DropDownList ID="customerService" runat="server" Height="22px" Width="200px">
<asp:ListItem>Option 1</asp:ListItem>
<asp:ListItem>Option 2</asp:ListItem>
</asp:DropDownList>
If I then wanted to calculate a price from what they select via a button, what would my best option be?
I.e If Service = 1 selected then cost = x,
else then cost = x- 이동됨David M MortonMVP2009년 11월 30일 월요일 오후 8:03ASP.NET (From:Visual C# General)

To answer your question, assign the Value attribute of the asp:ListItem in the code in front, and use SelectedValue in the code behind.

Hmm again fairly new to c#.. so just to confirm.
If I was to use a button that someone could click in which did the calculation for them depending on the value selected from the dropdown list, what would I need to do? (Don't quite understand what you mean) <asp:DropDownList ID="customerService" runat="server" Height="22px" Width="200px">
<asp:ListItem Value="15.99">Option 1</asp:ListItem>
<asp:ListItem Value="22.99">Option 2</asp:ListItem>
</asp:DropDownList>
cost = decimal.Parse(customerService.SelectedValue);
