How to check a radio button with Selenium WebDriver?

Question

I want to check this radio button, but I didn't know how. My HTML is:

<div class="appendContent">

    <div> id="contentContainer" class="grid_list_template">
        <div id="routeMonitorOptions"></div>
    </div>

    <input id="optionStopGrid" type="radio" name="gridSelector"/>
    <label for="optionStopGrid">Paradas</label>
</div>

Answer 1

Please try this code to select the radiobutton-

driver.findElement(By.cssSelector("input[id='optionStopGrid']")).click();
