Hello,

I'm currently writing a webpage that lists photos dynamically.
Depending on what was selected in the page previous, these photos will
change.  What I'd like to do it to have the user click on a photo and
for that to pull up another page associated with that photo.  I can't
figure out how to make this happen, however.  Here's my html referring
to the imagebutton:

<asp:DataList ID="DataList1" runat="server">
<AlternatingItemStyle BackColor="#FFFFCC"></AlternatingItemStyle>
<ItemStyle BackColor="White"></ItemStyle>
<ItemTemplate>
<table border="0" cellpadding="2" cellspacing="0" class="Normal">
<tr>
<td>
<asp:Imagebutton ID="imgPhotoGallery"  ImageUrl='<%#
Container.DataItem %>' Runat="Server" />
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>

And I can't seem to get this to attach to any function in the
corresponding .aspx file.

I initially thought it would be this function:

Protected Sub DataList1_SelectedIndexChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles DataList1.SelectedIndexChanged
        Dim sRedirect As String

        'go to edit page
        sRedirect = "Photo_Edit.aspx"
        Server.Transfer(sRedirect)
    End Sub

But that doesn't seem to work.

Please help!

Hi vortiger,

You should add a handler to a method inside the ImageButton code this
way :

<asp:Imagebutton
   ID="imgPhotoGallery"
   ImageUrl='<%# Container.DataItem %>'
   Runat="Server"
   OnClick="imgPhotoGallery_Click"  />

Then create the corresponding method :

protected void imgPhotoGallery_Click(object sender,
ImageClickEventArgs e)
{
   // Handle the redirect / transfer here
}

You also have the option to replace your ImageButton with a simple
link containing an image, and embed the destination url directly into
the link :

// datalist definition...
<td>
       <a href="<%# RedirectAddress %>">
       <asp:Image
         ID="Image1"
         runat="server"
         ImageUrl='<%# Container.DataItem %>'/>
       </a>
</td>
// datalist definition...

You could set RedirectAddress through a column in your data source,
for instance. This solution avoids the round-trip to the server. Of
course, this is only possible if redirecting is the only thing your
button does.

HTH,

Michel
