html - Display Value of a chossen ListItem from a DropDownList in VB -
i'm using vb , have dropdownlist want value displayed integer. if user chooses 15, display 'size: 300'
<asp:dropdownlist id="applist" runat="server" autopostback="true" width="110px"> <asp:listitem value="1000">15-1</asp:listitem> <asp:listitem value="500">15-2</asp:listitem> <asp:listitem value="300">15</asp:listitem> </asp:dropdownlist>
size:
the simplest option use code render block display selected value:
size: <%= applist.selectedvalue %>
of course, there plenty of other options. e.g. use label data-binding expression, require call page.databind()
:
size: <asp:label runat="server" text="<%# applist.selectedvalue %>" /> ' in code-behind protected sub page_load(byval sender object, byval e system.eventargs) handles me.load page.databind() end sub
