Change Parent cell based on child
posted

When a row is updated in the child container it subtracts that amount from the total amount in the parent row. I accomplished this by getting the numbers subtracting them and then setting the parent cell. It shows up perfectly but doesn't commit back to the database. If I postback that information is lost. How do I update the database with the new value?

var amount = eventArgs._cells[4]._old;

var newamount = eventArgs._cells[4]._val;

var parentindex = sender._parentRow._index

var grid = ig_controls["WebHierarchicalDataGrid1"].get_gridView();

var parentvalue = grid.get_rows().get_row(parentindex).get_cell(5).get_value()

var total = parentvalue-(newamount - amount);

grid.get_rows().get_row(parentindex).get_cell(5).set_value(total);

    Hello DMandy,

    Thank you for contacting us.

    I have tried to reproduce this behavior, although I couldn't, If you use BatchUpdating, you will need to call commit() in order to commit the changes, if not, they will be committed when post back is made (through a button for example). Could you please send me isolated sample that is reproducing the issue in order to investigate it further for you.

    Code snippet:

    function BandExitedEditMode(sender, eventArgs) {

    var grid = $find(sender.get_id());

    var editingCore = grid.get_behaviors().get_editingCore();

    editingCore.commit();

    }
