    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, everything works perfectly. If I make any changes to the
    controls in the form and resubmit the page, nothing changes. That is, viewing 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,
    Roshawn

    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, here'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 &amp; 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 expected and is called in the Page_Load event)
    Private Sub GetShoeResults()
    Dim hp As New MyHelper() 'declared variable for the MyHelper class for auxillary 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></RequesterCredentials>")
    .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></GetSearchResultsRequest>")
    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. :)
