all checkboxes "unchecked" initially

How to set all checkboxes in tree-grid to “unchecked” initially?



Thanks

The state of checkboxes based on value in XML, if it has 0 as value - they will be unchecked.
Also, you can use

grid.loadXML(function(){
grid.forEachRow(function(id){ grid.cells(id,INDEX).setValue(0); });
});

where INDEX - index of necessary column
