Re: Getting data out of gwt grid
I did not see a reply but here is what I did. Sinceyou have the store,
ask for the record at the row index and then the field name. For
instance, I have a store with fields named "property" and "value".
When I modify a value, I want the name of the "property" associated
with the value I changed. I already get the row and column from the
listener, eg.,
addEditorGridListener(new EditorGridListenerAdapter()
{public void onAfterEdit(GridPanel grid, Record record,
String field, Object newValue, Object oldValue,
int
rowIndex, int colIndex)
I then ask the store for the record at row (say 4), and then ask for
the value of the field "property"
store.getAt(4).getAsString("property")
This returns to me the name of the value I changed. Hope this helps.

Re: Getting data out of gwt grid
Thanks for the response but sorry, I got confused. I think I'm on the
wrong forum! I was actually referring to a GWT-EXT grid populated with
a Store. I think there is a significant difference. I've found the GWT-
EXT forum so I think I'll post there but if anyone can help out here
all the better.
Thanks.

Re: Getting data out of gwt grid
I'm assuming you just need to get the data from the grid.
This can primitevely be done using a single nested for-loop:
for (int i = 0; i < myGridWidget.getRowCount(); ++i) {
for (int j = 0; j < myGridWidget.getCellCount(i); ++j) { // this is safer
I guess since cols can span
// store data in array or some other type
arr[i][j] = myGridWidget.getText(i, j);
}
}

Getting data out of gwt grid
Hi, I'm a new member and I'm new to GWT. In the past week I've made quite good progress setting up an application to read data from mysql, and via rpc, populate combo boxes and grid on the client side. However, I'm stumped when it comes to returning records/fields back out out of the grid in response to user clicks. I have set up grid listeners to respond to clicks on cells, rows etc and they return me the relative integers no problem. But how do I get at the actual values in the fields. I've managed to work out I have to get the store out of the grid and get the record/field that I want out of the store but I'm stuck with the sequence of code that I need. And it's the one thing so far for which I have not been able to find an example. Any help and code sample would be very very much appreciated.
