I have a datagrid that displays all files in a folder. It works good, but I
need a extra column with a link for choosing image.
As shown in the code below I have made an ItemTemplate for this, and what I
need to do is to put the filename in the CommandArgument . How do I do that??
Is this the right way to do it, or is it a smarter way to put the filename
in a session-variable when clicking on the "Use this image"-LinkButton ?

CommandName="ch ooseImage" CommandArgument ="[HERE I WANT THE FILENAME]">Use
this image</asp:LinkButton>
</ItemTemplate>

<asp:HyperLinkC olumn DataNavigateUrl Field="Name"

Thanks for helping me!!!
