Identifying calls from anchors

[Guest]

I am busy doing a small application to get myself familiar with asp.net, and I have run into a problem. I have a list of anchors created with a repeater. I need to uniquely identify each anchor when doing a post back so that some data fields can be filled with the appropriate data. I have tried setting the id as follows:

<a href="#" id='<%#GetPhotoKey(Container.DataItem)%>' onserverclick='SelectAnchor_Click' runat="server"><%#GetPhotoTitle(Container.DataItem)%></a>

I get an "invalid identifier" error with the above code. Setting the name this way results in the server-side script being sent to the client.

The only other option I can think of is to reload the page (via the querystring). This brings up an entirely different problem that I would like to avoid if at all possible.

Any help would be greatly appreciated.

Why not use a LinkButton, which has CommandName and CommandArgument
properties? You can arrange to have a different CommandArgument for each
item in the repeater. You can see the CommandArgument when you handle the
Command event of the LinkButton.

Thanks for the tip; the link button is exactly what I needed. I didn't really know what the purpose of it was; now I do

Thanks!
