i have custom object contains fields , data of blog entry. items put list , supplied datagrid. 

   <asp:gridview id="grdrecentnews" runat="server" autogeneratecolumns="false" datakeynames="key"                             gridlines="none" pagesize="4" showheader="false"                             allowpaging="true">                             <pagersettings visible="false" />                             <columns>                                 <asp:templatefield>                                     <itemtemplate>                                         <blockquote>                                            <%-- <strong><a href=**"news.aspx"**>--%>                                             <strong><a href="news.aspx">                                                 <%#eval("newsdesc")%></a></strong>                                             <br />                                             <span class="italic">                                                 <%#eval("newsdate")%></span>                                         </blockquote>                                     </itemtemplate>                                 </asp:templatefield>                             </columns>                         </asp:gridview>

this code had in databound event, problem being want provide link 1 of fields of rss object. above below. want replace news.aspx" each item added datagrid rssobject's link property.

  protected sub grdrecentnews_rowdatabound(byval sender object, byval e system.web.ui.webcontrols.gridviewroweventargs) handles grdrecentnews.rowdatabound          if e.row.dataitem isnot nothing andalso e.row.dataitem.tostring = "rssentry"             dim curitem rssentry = ctype(e.row.dataitem, rssentry)             e.row.attributes.add("href", curitem.link) 'data-url         end if      end sub

i found way insert <%#eval %> statement attribute wanted change. point towards correct property of rssobject, , working. 

<columns>                             <asp:templatefield>                                 <itemtemplate>                                     <blockquote>                                         <strong><a href='<%#eval("link")%>'>                                             <%#eval("newsdesc")%></a></strong>                                         <br />                                         <span class="italic">                                             <%#eval("newsdate")%></span>                                     </blockquote>                                 </itemtemplate>                             </asp:templatefield>                         </columns>

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
