First issue is a display issue.  The two date selectors are just showing the drop down without an input and looks pretty awful, image below. Once you select a date you can't tell the selected date until you click done closing the editor.

Second, and far more critical to me, I can't figure out how to alter options of the editor in an event of the editor.  I want the second date to have a minimum date of the first date selector.  I am attempting to set that value.  I am pasting the code for these columns below as well.  I have tried using ui.owner and ui.editorInput instead of ui.editor with the same results.  The error I receive is: Uncaught Error: cannot call methods on igDatePicker prior to initialization; attempted to call method 'option'

startDate is a valid date.

{
    headerText: "Begin Date", width: "130px", key: "BeginDate", dataType: "date",
    columnSettings: {
        validation: true,
        editorType: "datepicker",
        editorOptions: {
            id: "actionStepStartDate",
            required: true,
            nullable: false,
            dataMode: "text",
            minValue: new Date(asYear, asMonth, asDate),
            valueChanged: function (evt, ui) {
                startDate = ui.newValue;
            }
        }
    }
},
{
    headerText: "End Date/<br />Deadline", key: "EndDate", dataType: "date",
    columnSettings: {
        validation: true,
        editorType: "datepicker",
        editorOptions: {
            id: "actionStepEndDate",
            required: true,
            nullable: false,
            dataMode: "text",
            maxValue: asMaxDate,
            dropDownListOpening: function (evt, ui) {
                if (startDate != null) {
                    console.log(ui);
                    $(ui.editor).igDatePicker("option", "minValue", startDate);
                }
 
            }
        }
    }
},

Thanks!
