Html form trouble

Hi,
On my asp.net page I have an html form. I've set runat attribute to server
and filled it with server controls. All settings
are as I like them.
So here's the problem: when I perform a search for the first time, everythin
g works perfectly. If I make any changes to the
controls in the form and resubmit the page, nothing changes. That is, viewi
ng the querystring, not a single value is altered
despite my doing so in the form itself.
Is there some problem with the html form? I can't for the life of me figure
this out. Any help would be greatly appreciated.
Thanks,

We'll need to see some code. Please post an extract of your code able to
reproduce the problems, stripping what is not necessary.
Greetings,

Hi Laurent. Sorry for the delayed response, been busy. As you requested, h
ere's some code.
HTML Form
<form runat="server" enableviewstate="false">
<label for="q">Search:</label><br/>
<input type="text" name="q" id="q" maxlength="100" /><br/>
<label for="sz">Shoe Size:</label><br/>
<asp:dropdownlist id="sz" runat="server" enableviewstate="false">
<asp:listitem value="-24">Any</asp:listitem>
<asp:listitem value="42802">5 & Smaller</asp:listitem>
<asp:listitem value="37090">6</asp:listitem>
<asp:listitem value="22806">7</asp:listitem>
<asp:listitem value="1032">8</asp:listitem>
'more listitems go here
</asp:dropdownlist><br/>
<label for="tp">Type:</label><br/>
<asp:dropdownlist runat="server" id="tp" enableviewstate="false">
<asp:listitem value="-24">Any</asp:listitem>
<asp:listitem value="2293">Athletic</asp:listitem>
<asp:listitem value="31920">Athletic-Inspired</asp:listitem>
</asp:dropdownlist><br/>
<label for="cd">Condition:</label><br/>
<asp:dropdownlist id="cd" runat="server" enableviewstate="false">
<asp:listitem value="-24">Any</asp:listitem>
<asp:listitem value="31919">New</asp:listitem>
</asp:dropdownlist><br/>
<input type="submit" id="submit" value="Search" />
</form>
Code to handle form (note that this uses the eBay XML API; it works as expec
ted and is called in the Page_Load event)
Private Sub GetShoeResults()
Dim hp As New MyHelper() 'declared variable for the MyHelper class for auxil
lary functions
Dim shoe As Shoe = New Shoe()'custom class
Dim sb As New StringBuilder("<?xml version=""1.0"" encoding=""utf-8""?>")
With sb
.Append("<GetSearchResultsRequest xmlns=""urn:ebay:apis:eBLBaseComponents"">
<RequesterCredentials><eBayAuthToken>" &
ConfigurationManager.AppSettings("Token") & "</eBayAuthToken></RequesterCred
entials>")
.Append("<CategoryID>63850</CategoryID><DetailLevel>ReturnAll</DetailLevel>"
)
If Request.QueryString("q") <> "" Then
.Append("<Query>" & Request.QueryString("q") & "</Query>")
End If
.Append("<SearchRequest><AttributeSetID>22</AttributeSetID><ProductFinderID>
22</ProductFinderID>")
'for the Size Parameter
If Request.QueryString("sz") <> "" Then
'turn off all selected items
For i = 0 To Me.sz.Items.Count - 1
Me.sz.Items(i).Selected = False
Next
.Append("<SearchAttributes><AttributeID>53</AttributeID><ValueList><ValueID>
" & Request.QueryString("sz") &
"</ValueID></ValueList></SearchAttributes>")
Dim item As ListItem
For Each item In Me.sz.Items
If item.Value = Request.QueryString("sz") Then
shoe.Size_ID = item.Value
shoe.Size = item.Text
item.Selected = True
Exit For
End If
Next
End If
'for the Type Parameter
If Request.QueryString("tp") <> "" Then
'turn off all selected items
For i = 0 To Me.tp.Items.Count - 1
Me.tp.Items(i).Selected = False
Next
.Append("<SearchAttributes><AttributeID>54</AttributeID><ValueList><ValueID>
" & Request.QueryString("tp") &
"</ValueID></ValueList></SearchAttributes>")
Dim item As ListItem
For Each item In Me.tp.Items
If item.Value = Request.QueryString("tp") Then
shoe.Type_ID = item.Value
shoe.Type = item.Text
item.Selected = True
Exit For
End If
Next
End If
'for the Condition Parameter
If Request.QueryString("cd") <> "" Then
'turn off all selected items
For i = 0 To Me.cd.Items.Count - 1
Me.cd.Items(i).Selected = False
Next
.Append("<SearchAttributes><AttributeID>94</AttributeID><ValueList><ValueID>
" & Request.QueryString("cd") &
"</ValueID></ValueList></SearchAttributes>")
Dim item2 As ListItem
For Each item2 In Me.cd.Items
If item2.Value = Request.QueryString("cd") Then
shoe.Condition_ID = item2.Value
shoe.Condition = item2.Text
item2.Selected = True
Exit For
End If
Next
End If
'Add Pagination in case a page number is returned in the querystring
.Append("<Pagination><EntriesPerPage>10</EntriesPerPage></Pagination></GetSe
archResultsRequest>")
End With
Try
Me.Xml1.DocumentContent = hp.CreateHeaders(sb.ToString())'call to eBay
Dim ext As New XsltArgumentList()
ext.AddExtensionObject("urn:Shoes", shoe)
Me.Xml1.TransformArgumentList = ext
Me.Xml1.TransformSource = "search.xslt"
Catch ex As WebException
'handle errors here
End Try
End Sub
I hope this helps you help me. Thanks for being interested. :-)
