Dynamic form item in grid list

[lukepham90]

I'm working with a SmartGWT grid that has two fields. The second field needs to dynamically switch between a SelectItem and a TextItem based on the chosen value in the first field (which is also a SelectItem). Could you provide some code to achieve this functionality?

If you'd like such code written for you, we offer Consulting services (billed hourly).

Otherwise, a common approach would be to use formItem.visibleWhen to declaratively control which item is visible.

Hi lukepham90

see the code below. I have a non-editable first "type"-column and depending on that column I choose an editor.
You'll also need to look into context.getEditField() to always return a TextItem (?) for your 1st column and sth similar to my code for your second column:

setEditorCustomizer(new ListGridEditorCustomizer() {
            public FormItem getEditor(ListGridEditorContext context) {
                String firstField = context.getEditedRecord().getAttributeAsString("firstField");
                if (firstField.equals("selectYesNo")) {
                    return new SelectItemYesNo();
                } else if (firstField.equals("bigfield") {
                    return new TextAreaItem();
                } else {
                    return new TextItem();
                }
            }
        });

Also see this sample.
