Responding to UnboundCheckbox checkstate change on client side

IDoE Developer posted over 10 years ago

I have a WebHierarchicalDataGrid with 1 parent and 1 child band. I have an unboundcheckbox in both the parent and the child bands. When a user checks the checkbox in the parent level I need to respond to the check and set the checks on any child rows to match it. Is there and example some where for doing s this?

Hello Ruth,

Please have a look at the attached sample of WebHierarchicalGrid with Unbound CheckBoxFields in the parent and in the child bands.

The solution is implemented on the client (client-side) and on cell updating event I get the index of the row and expand it in order to get the Child Band and later to check all child rows.

Code snippet:

<script type="text/javascript" id="igClientScript">

        function whdg_CellValueChanged(sender, eventArgs) {

            if (eventArgs.get_cell().get_column().get_key() === "CheckParent") {

                var rowIndx = eventArgs.get_cell().get_row().get_index();

                ig_controls.whdg.get_gridView().get_rows().get_row(rowIndx).set_expanded(true);

                setTimeout(function () {

                    var gridRows = ig_controls.whdg.get_gridView().get_rows().get_row(rowIndx).get_rowIslands()[0].get_rows();

                    var length = gridRows.get_length();

                    for (var i = 0; i < length; i++) {

                        gridRows.get_row(i).get_cellByColumnKey("CheckChild").set_value(true);

                        gridRows.get_row(i).get_cellByColumnKey("CheckChild")._setCheckState(true);

                    }

                }, 200);

            }

        }
