asp.net c# gridview buttons -


i'm having trouble getting gridview's button column anything. i'm using directoryinfo object details of file. put filename , date created gridview columns. third column button column. have set datakeys(name, creationtime), named button column's commandname "sendcommand". want send filename page. have code rowcommand event:

protected void gvfiles_rowcommand(object sender, system.web.ui.webcontrols.gridviewcommandeventargs e) {      if (e.commandname == "sendcommand")     {          int index = convert.toint32(e.commandargument);          string fileid = ((gridview)sender).datakeys[index]["name"].tostring();         response.redirect("irmain.aspx?@filename=" + fileid);      } }

nothing happens, except postback think. how do this? 

<asp:gridview id="gvfiles" runat="server" font-name="verdana" font-names="verdana"          width="401px" autogeneratecolumns="false" backcolor="white"          bordercolor="black" borderstyle="ridge" borderwidth="2px"          datakeynames="name,creationtime"          >         <columns>             <asp:hyperlinkfield accessibleheadertext="file name"                  datanavigateurlfields="name" datanavigateurlformatstring="~\assets\reports\{0}"                  datatextfield="name" headertext="file name" >                  <headerstyle backcolor="#0033cc" forecolor="white" />             </asp:hyperlinkfield>             <asp:boundfield accessibleheadertext="date" datafield="creationtime"                  dataformatstring="{0:d}" headertext="date">                 <headerstyle backcolor="blue" forecolor="white" />             </asp:boundfield>              <asp:buttonfield buttontype="button" text="do stuff" commandname="sendcommand"                  headertext="what?!" />          </columns>          <alternatingrowstyle backcolor="#6699ff" />      </asp:gridview>

you have add onrowcommand attribute gridview in aspx, otherwise gridview doesn't know method call when execute command on it.

afaik entirely optional attribute , isn't generated via designer have add manually when want use it.
