Hi,
I have a question regarding an issue on submitting a form multiple times. For some reason, my form takes one submit, but then the others, I don't see changes of result. Here is the app:
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.XML" %>
<script runat="server">
Sub submit(ByVal sender As Object, ByVal e As EventArgs)
mess.Text = "You selected " & drop1.SelectedItem.Text
Dim file As String = Context.Server.MapPath("music.xml")
Dim document As XmlDocument = New XmlDocument()
document.Load(file)
Dim songList As XmlNodeList
songList = document.SelectNodes("/music_songs/song[category='" & drop1.SelectedItem.Text & "']")
Dim song As XmlNode
For Each song In songList
Dim title As XmlNode = song.FirstChild
songNodesOut.Text &= "<b>Title:</b> " & title.InnerText & "<br/>"
Dim category As XmlNode = title.NextSibling
SongNodesOut.Text &= "<b>Category:</b> " & category.InnerText & "<br /><hr />"
Next
end Sub
</script>
<html>
<body>
<form runat="server">
<div>
<asp:DropDownList id="drop1" runat="server">
<asp:ListItem>Rock</asp:ListItem>
<asp:ListItem>Blues</asp:ListItem>
</asp:DropDownList>
<asp:Button Text="Submit" OnClick="submit" runat="server"/>
</form>
<p><asp:label id="mess" runat="server"/></p>
<asp:Label id="songNodesOut" runat="server" />
</div>
</body>
</html>In other words, if I first make Rock as my selection from drop down list, the songs are listed correctly, but if I try and select on the Blues, even though those songs exist, I only see the same songs from the other list. Is there something here that I missed?
Thanks for your help.
