c# - Command Argument not working link button -

i have link button , set of records. when link button of specific record clicked, want id of record passed code behind. code have used:

<asp:linkbutton id="likes" runat="server"  oncommand="linkbutton1_click"    commandargument='<%#eval("datarow["id"]") %>' commandname="like">     click</asp:linkbutton> 

and in cs file have used:

  protected void linkbutton1_click(object sender,  commandeventargs e)       {          int x = int32.parse(e.commandargument.tostring());       } 

but command argument null here. can please me?

you handle wrong event. think linkbutton inside control @greg84 said, example, handle event itemdatabound of datagrid or repeater .

protected void control_itemdatabound(object sender, controlitemeventargs e)  {     linkbutton likes = (linkbutton)e.item.findcontro("likes");     // write code here handle click     // ... }
