I am trying to modify the value that is displayed in a DataGrid cell after
the user has entered or modified the existing value. For example, if the
user enters "5/6/12" I want the cell to display "05/06/2012" when the user
exits the cell. Here is the code that creates the column:
final TextInputCell fosterDateStartCell = new TextInputCell();
final Column<IFosterHistoryProxy, String> fosterDateStartColumn;
fosterDateStartColumn = new Column<IFosterHistoryProxy,
String>(fosterDateStartCell) {
@Override
public String getValue(final IFosterHistoryProxy fosterHistory) {
final String date = fosterHistory.getFosterDateStart();
if (GLGWTUtil.isEmpty(date)) {
return "";
}
return date.substring(4, 6) + "/" + date.substring(6, 8) + "/" +
date.substring(0, 4);
}
};
fosterDateStartColumn.setFieldUpdater(new FieldUpdater<IFosterHistoryProxy,
String>() {
@Override
public void update(final int index, final IFosterHistoryProxy
fosterHistory, final String value) {
final String[] dateParts = value.split("/");
if (dateParts.length != 3) {
return;
}
final int month = Integer.valueOf(dateParts[0]);
final int day = Integer.valueOf(dateParts[1]);
final int year = Integer.valueOf(dateParts[2]);
final String date = (year < 100 ? 2000 + year : year) + (month < 10
? "0" : "") + month +
(day < 10 ? "0" : "") + day;
getEditDTO(fosterHistory,
ECacheUpdateType.Update).setFosterDateStart(date);
final ViewData viewData = new ViewData(date.substring(4, 6) + "/" +
date.substring(6, 8) +
"/" + date.substring(0, 4));
fosterDateStartCell.setViewData(fosterHistory.getFosterHistoryId(),
viewData);
fosterHistoryGrid.redraw();
}
});
fosterDateStartColumn.setSortable(true);
fosterHistoryGrid.addColumn(fosterDateStartColumn, "Start Date");
fosterHistoryGrid.setColumnWidth(fosterDateStartColumn, "10ex");
The getValue() method is working well ... if the value in the proxy object
is "20120506" then I see "05/06/2012" in the cell. But the update() method
is not showing the correct value ... if the user enters "5/6/12" then I do
not see "05/06/2012" (the value in the cell is still "5/6/12" after the
update() method has executed). Note that the setFosterDateStart() method
does not cause the update to be sent to the server; it simply sets the
value in the editable proxy object. Also note that the
getFosterHistoryId() method returns the stable identifier value for the
IFosterHistoryProxy object, and that the key provider for the selection
model associated with the DataGrid is using that identifier.
Many thanks for any help!
