                <p><span class="initial-space"></span>This sample demonstrates how to show or hide the column header and footer in the Grid component. The header and footer visiblity is determined by following properties:</p>
                <ul class="feature-points">
                    <li><span style="color:#c60d0d">showHeader</span> - determines whether the grid header is visible or not, by default set to true</li>
                    <li><span style="color:#c60d0d">showFooter</span> - determines whether the grid footer is visible or not, by default set to true</li>
                </ul>
                <p><span class="initial-space"></span>When both of these properties are set to false, and in addition if you set the <span style="color:#c60d0d">gridLines</span> property to None, the Grid will appear like a <a routerLink="/listbox">ListBox</a>. Because the ListBox component only shows data in a single column, the Grid may be better to use here. It will allow you to easily present data in more uniform way.</p> 
                <p><span class="initial-space"></span>For more information check out the source code of this sample (<i>grid/grid-show-hide-header-footer.ts</i>) file.</p>
