Customer Action in GridView

[TeamN2]

I am having an issue creating a column in a GridView control using c#. when the user clicks the delete link i want the logic to delete the database record and also an associated file. thusly i created a page that using a paramater passed in the url would display a confirmation message then delete the file. I am simply trying to insert a TemplateField containing a link to my delete confirm page. the problem is that im not sure how to insert the needed information into the link i.e.(the file id from the DataKeyNames array) Here is the code i am using for my GridView

<asp:GridView ID="gvTempFiles " runat="server" AllowPaging="Tr ue" AllowSorting="T rue"
AutoGenerateCol umns="False" DataKeyNames="F ileID" DataSourceID="T empFileDataSour ce"
>
<Columns>
<asp:BoundFie ld DataField="File Name" HeaderText="Fil eName" SortExpression= "FileName" />
<asp:BoundFie ld DataField="File Desc" HeaderText="Fil eDesc" SortExpression= "FileDesc" />
<asp:BoundFie ld DataField="File Type" HeaderText="Fil eType" SortExpression= "FileType" />
<asp:TemplateFi eld>
<ItemTemplate >
<a href="PicDetail .aspx?id="" >Delete</a>
</ItemTemplate>
</asp:TemplateFie ld>
</Columns>
</asp:GridView>

Thanks for any help you can give

use the DeleteCommand event to do this, and also use the alert("") for confirmation instead of transferring to another page.

Is there a simple way to get back the selected datakey when using the rowdelted or rowdeleting event. so far whenever i have tried to use either of these event the selecteddatakey is always set to null
