Question

I am trying to get values from a select multiple box like this but the breakpoint at For Each Item in box is nothing, what am I doing wrong? Please advice, thanks:

   Dim box = Request.Form("outletToBox")
     For Each item In box
         Dim abc As String = item.ToString
         Dim cdf As String = abc
     Next

我的选箱:

 <select multiple size="8" style="width: 135px" runat="server" onblur="selectAll(this, true, document.getElementById( <%#uilblDestinationQualOutlet.ClientID%> ))"
    id="outletToBox" onclick="return outletToBox_onclick()">
  </select>

Answer 1

Actual no name parameter is specified in your HTML. That s why is nothing. And also, if you re using MVC or something else, be careful that the name parameter will be given from the webapp itself, so your Request.Form("mykeyhere") will be invalid.

因此,你有两个解决办法:

give a proper name attribute to your select item or,
use outletToBox.SelectedItems where you read your Post data.

Answer 2

you can try like this....

for i=0 to Request.form("listbox name").count-1
listboxvalue=Request.form("listbox name").item(i)
 Response.write listboxvalue & "<br>"
next
