Title: Updating main grid from detail grid
Post by: KR on August 10, 2016, 02:27:24 pm

I have a main grid with track changes enabled.

In the “cellSave” of the detail grid I update a value in the data of the parent main grid. The new value shows as expected.

However, when doing:

Code: [Select]

var changes = $gridMain.pqGrid("getChanges", {
                    format: 'byVal'
});

Does not return the changes that were made from the detail grid.

It looks like track changes were not triggered. Is it possible to trigger this and how can that be done?

Thank you!

Following code is in context of this demo: http://paramquery.com/pro/demos/nesting

First of all enable tracking in the main grid.

1) trackModel: {on: true}
2) dataModel.recIndx = "OrderID"

You should use updateRow() method to make changes in the main grid:

Code: [Select]

//cellSave of the detail grid.
cellSave: function(){
var ri = gridMain.getRowIndx({rowData: rowData}).rowIndx;
gridMain.updateRow({
rowIndx: ri,
newRow: {"ShipVia": 'changed'}
})
console.log(gridMain.getChanges());
},

Note: you should be able to see a red triangle in the top left corner of the dirty cells.

This works great!

I was not using updateRow(). Instead I updated the rowData directly.

Thank you!
