protected void btndelete_click(object sender, eventargs e) {     foreach (repeateritem aitem in rptinbox.items)     {         htmlinputcheckbox chk = (htmlinputcheckbox)aitem.findcontrol("chkrow");          if (chk.checked == true)         {             string id = chk.value.tostring();              sqlconnection con = new sqlconnection(constr);             sqlcommand cmd = new sqlcommand("delete mailbox mailboxid='"+id+"'", con);             try             {                 con.open();                 cmd.executenonquery();             }             catch (exception er)             {              }                         {                 con.close();             }         }     } }

this html:

<asp:repeater id="rptinbox" runat="server">     <itemtemplate>         <tr>             <td><input type="checkbox" id="chkrow" value='<%#eval("mailboxid")%>' runat="server"/></td>             <td><%#eval("from") %></td>             <td><a href="inboxdetail.aspx?mailboxid=<%#eval("mailboxid") %>"><%#eval("subject") %></a></td>             <td><%#eval("date") %></td>         </tr>     </itemtemplate> </asp:repeater>

you can store value in hidden field:

<asp:repeater id="rptinbox" runat="server">     <itemtemplate>         <tr>             <td>                 <input type="checkbox" id="chkrow" runat="server"/>                 <input type="hidden" id="hiddenmailboxid" value='<%# eval("mailboxid") %>' runat="server"/>             </td>             <td>                 <%#eval("from") %>             </td>             ...         </tr>     </itemtemplate> </asp:repeater>

and retrieve in code-behind:

htmlinputhidden hiddenmailboxid = aitem.findcontrol("hiddenmailboxid") htmlinputhidden; string id = hiddenmailboxid.value;

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
