-

i have repeater inside updatepanel. inside repeater item have several text boxes. have "add new" button dynamically add new items repeater. problem every time press "add new" user input erased. how update repeater preserving user input?

whenever postback occurs, repeater control loses state. might want perform following quick steps on postback.

  1. convert repeater data form of data array (da) in code-behind.
  2. add empty element da.
  3. bind da repeater control.

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
