Hi Stefan
A new day a new issue.
So the situation for now:
I have a for row long table (filtered model) with two columns. For example:
true, item1
true, item2
false, item3
false, item4
And I have 3 buttons: Show all, Checked, Unchecked.
After init the table is in Sholl all state.
Thanks to your modification code when in Shaw all state I change the value
of checkboxes everything just works fine.
But:
When I change a cb value in filtered view (when I see only table rows in
which the first cell contains only unchecked or checked checkboxes) the
mechanism go broke. Because after this change the tableModel will contains
only the visible rows and forget the filtered-out ones.
Here is my code for the cellClick event, where I change the chekboxes value:
<code>
table.addListener("cellClick", function(e) {
if (e.getColumn() == 1) { // if clicked cell is in the first
column change checkbox
var selectedRowIndex, selectedRowData
selectionModel.iterateSelection(function(index) {
selectedRowIndex = index;
selectedRowData = (tableModel.getRowData(index));
});
if (selectedRowData[1] !== null) { // if the cell
contains checkbox
var newTableModel = [];
var newRowData = [[selectedRowData[0],
!selectedRowData[1], selectedRowData[2]]];
tableModel.setRows(newRowData, selectedRowIndex);
}
}
});
</code>
I wonder if there is a possibility to manipulate tableModel in filtered
state without data loss.
Greetings
Daniel
