Set hyperlink NavigateUrl property like...NavigateUrl='<%# Eval("FileID", "show.aspx?ID={0}" %>'

NavigateUrl='<%# Eval("FileID", "show.aspx?ID={0}") + "&FilePath=" + Eval("FilePath") %>'

add onRowCommand Event in your grid

OnRowCommand="OnRowCommand_GridView1"

Then define link Button with the CommandName and CommandArgument

      <asp:LinkButton ID="lnk1" runat="server" Text="DoClick"  CommandName="Select" CommandArgument='<%#Eval("FileID") %>'></asp:LinkButton>

and than on code behind

protected void GridView1_OnRowCommand(object sender, GridViewCommandEventArgs e)
    {

       if (e.CommandName == "Select")
        {
          int MyFileID = e.CommandArgument;
       //Now Perfrom here ur desired action
       }

Hope this will help you.
