FEATURED COMPONENTS
First time here? Check out the FAQ!
I have the following case:
I have three tabs and in each tab, I have a Grid
.
The data for each Grid
is coming from a database, so I am using rowRenderer
to populate the Grids. The following code is common for all three Grids:
<grid id="myGrid1" width="950px" sizedByContent="true" rowRenderer="com.example.renderer.MyRowRenderer">
The rows are constructed from Doublebox
objects. The data is populated successfully.
I need to handle a multiple-cell editing on the client side.
As example let's say that the user edits first cell on the first row and the value should be
propagated to all other cells on the same row.
I am using jQuery
to do this value propagation and it works OK.
I am passing the jQuery as follows:
doublebox.setWidgetListener(Events.ON_CHANGING, jQuerySelectors);
doublebox.setWidgetListener(Events.ON_CHANGE, jQuerySelectors);
This makes it possible to change the value in 1 cell and the change is instantly (visually) seen in all other cells filtered by jQuery selectors.
The problem is that the value is visually distributed to all the cells, but when I try to save the Grid data back to the database, the background values are the old ones. I am assuming that ZK Grid component is not aware that jQuery changed all the cell values. Nevertheless if I manually click on a cell that already has the NEW value (enter/leave/change focus) when I save the grid the NEW value is correct in that particular cell. Maybe that's a hint how can I resolve this.
Code how I extract the Grid values:
Grid tGrid = (Grid) event.getTarget().getFellow("myGrid1");
ListModel model = tGrid.getModel();
MyCustomRow tRow = (MyCustomRow)model.getElementAt(i);
The model for my Grid is a List
of MyCustomRow
so like:
myGrid1.setModel(new ListModelList(List<MyCustomRow> populatedList));
I have a couple of assumptions, but whatever I have tried, hasn't worked. I have in mind that jQuery events and ZK events are different and probably isolated in different contexts. (Although I have tried to fire events from jQuery and so on..)
Do you have any suggestions? As a whole is my approach correct or there's another way to do this? Thanks for your time in advance!
I had a similar issue and solved the problem by sending the AU request telling the server about the update manually:
if (comp.$instanceof(zul.wgt.Checkbox)) {
if (!comp.isDisabled()) {
if (checked == undefined) {
// toggle
checked = !comp.isChecked();
}
comp.setChecked(checked);
// fire event to update binding
zAu.send(new zk.Event(comp, "onCheck", {
"" : checked
}, {
toServer:true
}));
}
}
I found Firebug quite useful to learn how the AU message must look like. As a shorter alternative, you can use
comp.fire("onCheck", [{"" : checked}], {toServer:true});
of course, after minor adaption to Doublebox.
