Hello,

I am trying to check a checkbox on a webpage that has been loaded through the webbrowser control.

This is the code from the webpage

XML

<div class="uploadFormLine" id="uploadTerms">
        <input type="checkbox" name="terms" id="terms" onclick="checkTerms()" />
        <label for="terms"><strong></strong></label>
      </div>

I have tried

HtmlElement checkBox = doc.GetElementById("terms");
checkBox.InvokeMember("Click");

and...

webBrowser1.Document.GetElementById("terms").InvokeMember("CLICK");

neither of them are working..any help would be appreciated...thank you!

you need WebBrowser.DocumentCompleted Event[^]
sample code:

C#

webBrowser1.DocumentCompleted +=
        new WebBrowserDocumentCompletedEventHandler(DoSomething);
private void DoSomething(object sender,
    WebBrowserDocumentCompletedEventArgs e)
{
    // find checkbox and invoke here...
}

Hey,

Thank you for the reply. Sorry, I forgot to mention I do have that code. I have code in the same block working with a text box on the page but for some reason it won't respond to the check box. I think it may have something to do with the html in the code "onclick" or a confusion with another id named "terms". I also tried focusing the text box which worked but would not click. I'm not sure really...it might also have to do with parent or child elements. If there is anyone that has solved this before any help or direction would be appreciated and hopefully my problem is clear. Thank you.
