Question

I am making a bot which has a WebBrowser control which loads some pages. There is a checkbox that I want to be unchecked by my bot. Right now I am using this code:

HtmlElementCollection elc = this.BotBrowser.Document.GetElementsByTagName("input");
foreach (HtmlElement el in elc)
{
    if (el.GetAttribute("value").Equals("Leishmania mexicana")) //to uncheck Leishmania mexicana checkbox
    {
        el.InvokeMember("click");

    }
}

But this seems not perfect because it sometimes re-checks the checkbox as this bot has to load pages and perform the task more than 100 times.

Here is the HTML tag of the checkbox:

<input type="checkbox" class="jstree-real-checkbox" id="array(BlastDatabaseOrganism)" name="array(BlastDatabaseOrganism)" value="Leishmania mexicana" checked="checked">

Is there any way I can remove this attribute or set its checked attribute to null?

Answer 1

Try this

el.SetAttribute("checked", null);
