Object datasource and Querystring roblem

Hello experts,

I am having trouble assigning a querystring value to a business object parameter.when I do the following;-

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetGalleryImagesByID"
                TypeName="FixedAuctions.AuctionsDB">
                <SelectParameters>
                    <asp:QueryStringParameter DefaultValue="-1" Name="GalleryID" QueryStringField="GALLERYID"
                        Type="Int32" />
                </SelectParameters>
            </asp:ObjectDataSource>
I get error;-



Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I f I change the follwoing line;-

<asp:QueryStringParameter DefaultValue="-1" Name="GalleryID" QueryStringField="GALLERYID"
                        Type="Int32" />


to-
<asp:QueryStringParameter DefaultValue="1" Name="GalleryID"
                        Type="Int32" />

everything works fine.

I am using the code in a popup that is called in a javascript function like so;-

HyperLink HyperLink1 = (HyperLink)DataList1.Items[i].FindControl("HyperLink1");
                HyperLink1.Attributes.Add("onclick", "window.open('popup.aspx?IMAGEID=IMAGEID',null,'height=550, width=650,status= no, resizable= no, scrollbars=no, toolbar=no,location=no,menubar=no ');");

I can't seem to find what am missing

without looking deeper into your code, you have
<asp:QueryStringParameter DefaultValue="-1" Name="GalleryID" QueryStringField="GALLERYID" Type="Int32" />
and your link doesnt have a querystring GALLERYID, instead it has a Querystring IMAGEID

Hi there,

I had to change this;-


HyperLink1.Attributes.Add("onclick", "window.open('popup.aspx?IMAGEID=IMAGEID',null,'height=550, width=650,status= no, resizable= no, scrollbars=no, toolbar=no,location=no,menubar=no ');");
to

 HyperLink1.Attributes.Add("onclick", "window.open('popup.aspx?IMAGEID="+IMAGEID+",null,'height=550, width=650,status= no, resizable= no, scrollbars=no,

IE.
IMAGEID=IMAGEID'

to

IMAGEID="+IMAGEID+",
