안녕하세요

두가지 문의드립니다.

1. 아래에서 c1-flex-grid-selector로 선택된 값을 가져오는 방법

<c1-flex-grid id="FlexGrid" auto-generate-columns="false" allow-sorting="true" class="grid" ime-enabled="true" allow-add-new="true" allow-delete="true" auto-clipboard="true">

    <c1-items-source batch-edit-action-url="@Url.Action("RemoteBindBatchEdit")" disable-server-read="true"></c1-items-source>

    <c1-flex-grid-column binding="userId"></c1-flex-grid-column>

    <c1-flex-grid-column binding="userName"></c1-flex-grid-column>

    <c1-flex-grid-column binding="userEmail"></c1-flex-grid-column>

    <c1-flex-grid-column binding="guidSalt" is-read-only="true"></c1-flex-grid-column>

    <c1-flex-grid-column binding="rngSalt" is-read-only="true"></c1-flex-grid-column>

    <c1-flex-grid-column binding="passwordHash" is-read-only="true"></c1-flex-grid-column>

        <c1-flex-grid-selector show-check-all="true"></c1-flex-grid-selector>

</c1-flex-grid>

2. 아래 코드로 버튼이 생성되지않습니다.

function createButton(CellMaker) {
            return CellMaker.makeButton({
                text: '<b>${item.Country}</b> Button',
                click: function (e, ctx) {
                    alert('Clicked Button ** ' + ctx.item.Country + ' **');
                }
            });
        }

<c1-flex-grid-column binding="Country" header="CellMaker Button" width="150" align="center" template-function="createButton"></c1-flex-grid-column>
