javascript - infragistics webdatagrid get selected cell from keydown event in client side -


i have build infragistics webdatagrid in c# :

        var columnone = new bounddatafield();         columnone.datafieldname = "columnone";         columnone.key = "columnone";         columnone.header.text = "columnone";          var columntwo = new bounddatafield();         columntwo.datafieldname = "columntwo";         columntwo.key = "columntwo";         columntwo.header.text = "columntwo";          webdatagridobject.datakeyfields = "columnone";         webdatagridobject.columns.add(columnone);         webdatagridobject.columns.add(columntwo);

i javascript update cell column 2 when typed in cell column one.

for example, user starts typing value in cell @ line 3 , column one, cell @ line , column 2 must automatically updated constant value, "updated".

to that, bit struggling, have attach lot of client events c#, , think 1 usefull keydown :

webdatagridobject.clientevents.mousedown = "webdatagridview_mousedown"; webdatagridobject.clientevents.keydown = "webdatagridview_keydown"; webdatagridobject.behaviors.editingcore.behaviors.cellediting.celleditingclientevents.enterededitmode = "enterededitmode"; webdatagridobject.behaviors.editingcore.behaviors.cellediting.celleditingclientevents.exitededitmode = "exitededitmode";

i js keydown event handler, getting column key of cell edited, , if it's equals "columnone", update value of cell @ same line , on column two. js :

function webdatagridview_keydown(webdatagrid, evntargs) {   }  function webdatagridview_mousedown(webdatagrid, evntargs) { // trying column key of edited cell     webdatagrid.get_behaviors().get_selection().get_selectedrowsresolved()    [0].get_cell(3).get_text()  }  var gridref; var cellref;  function enterededitmode(grid, args) {     gridref = grid;     cellref = args.getcell();     if (cellref._column._key === "headername") {         alert('toto');     } }   function exitededitmode(grid, args) {     gridref = null;     cellref = null; }

to column key, should try this:

    webdatagrid.get_behaviors().get_selection().get_selectedrowsresolved()[0].get_cell(3).get_column().get_key();

or this:

   webdatagrid.get_behaviors().get_selection().get_selectedrowsresolved()[0].get_cell(3).get_column()._datafieldname

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
