Separate Grid

Master Detail (Vue)

The simplest way to deal with hierarchical data is the master-detail model. Use a control to select the main item and one or more additional controls to show the main item's details.

    <div class="container-fluid">
        <p>
            For example, the ComboBox below is used as a master control.
            Select a country from the combo and the grid below will show the items in that country:
        </p>

        <label>Select a country:
            <wj-combo-box :initialized="initCountriesCombo" :itemsSource="countries"
                :selectedIndexChanged="onCountriesSelectedIndexChanged" />
        </label>
        <wj-flex-grid :itemsSource="detailView" />

        <p>
            In the next example, The FlexGrid is used as the master
            control. Select an item on the grid and see the details
            in the controls below:
        </p>

        <h3>Master</h3>
