<h1>Control and Initialized Attributes</h1>

    <p>This is a <b>FlexGrid</b> control. We will use the "control" attribute to get a reference to the control and create the columns:</p>
    <wj-flex-grid
        items-source="data"
        auto-generate-columns="false"
        control="flex">
    </wj-flex-grid>
    
    <p>This is a <b>FlexGrid</b> control. This time we will use the "initialized" attribute to create the columns:</p>
    <wj-flex-grid
        items-source="data"
        auto-generate-columns="false"
        initialized="init(s,e)">
    </wj-flex-grid>

</div>
