    <p>I'm seeing a few questions related to this on SO already, but I think mine is sufficiently different to not be considered a duplicate (if I'm wrong let me know).</p> <p>I have an ActiveX control I've written in C# and while I have it mostly working, I want to raise an event in JavaScript when it's clicked (it displays an image so it's a visual element on the page). </p> <p>The end goal of what I'm looking to accomplish is no different than if it were a <code>&lt;span&gt;</code> tag and it had an <code>onclick</code> event to raise a JavaScript function when the area of the tag were clicked.</p> <p>Most of the <a href="https://stackoverflow.com/questions/150814/how-to-handle-an-activex-event-in-javascript/379872#379872">stuff I've read</a> on it goes into very fine detail on how to handle events in an ActiveX control and send info back/forth, and that's fine, but it seems overly complicated. I'm not looking to communicate with the ActiveX control, I just need a JavaScript function to fire off when I click it, in a way similar to a <code>&lt;span&gt;</code> or <code>&lt;div&gt;</code> tag. I can handle everything else in JavaScript. Simply wrapping the control in a <code>&lt;span&gt;</code> or <code>&lt;div&gt;</code> with an <code>onclick</code> event has no effect - the ActiveX control pretty much overrides it.</p> <p>Is there a simple way to handle this for an ActiveX control written in C#?</p> <p>I guess another way of putting it is - I'm working with a third party control and we have to use code similar to the following to get it to communicate with our HTML page via JavaScript</p> <pre><code>&lt;script type="text/javascript" event="OnMouseClick(index)" for="AXObjectName"&gt; &lt;!-- AXObjectName_OnMouseClick(index); //--&gt; &lt;/script&gt; </code></pre> <p>Where <code>AXObjectName</code> is the name/id of the control and <code>AXObjectName_OnMouseClick</code> is the name of the JavaScript function it will fire in my code, passing an <code>index</code> parameter. However, what all do I have to do to set up a method like <code>OnMouseClick</code> in the control? And if I don't want to pass any actual information (i.e., no <code>index</code>) do I even have to go this far?</p>

    1. COI'm guessing you've already seen this code sample: http://www.c-sharpcorner.com/UploadFile/dsandor/ActiveXInNet11102005040748AM/ActiveXInNet.aspx

    2. COI actually just included the link so I can find it on my other computer. I'm going to try an ActiveX control experiment myself and maybe figure out the event thing. It looks relatively straightforward.

    3. CO@MusiGenesis: yeah, and it's one of the ones I followed to get this far. What it doesn't do, though, is show how interacting with the ActiveX control can have any effect on the JavaScript in the page.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
