Testing control properties

Is there a way to test if a control in enabled or disabled, background colors etc? So if I grab a <asp:imagebutton control and I tell if it is enabled?

Re: Testing control properties

Hey Srhone,

These are all attributes that get added to the rendered html tag (disabled="disabled" for instence). You will need to get a collection of the attributes (HtmlElementAttributeReader) for that element and then verify using those. Bellow is some code showing how to get the HtmlElementAttributeReader for an element.

HtmlPage page = new HtmlPage("SomePage.aspx");
HtmlElement element = page.Elements.Find("ControlID");
HtmlElementAttributeReader reader = element.GetAttributes();
//Some common attributes are strongly typed properties
Assert.AreEqual("Expected", reader.Class);
//Other attributes are indexed through the collection
Assert.AreEqual("Expected", reader["disabled"]);

So this method only appears to work for a small number of properties.

Can you give an working example on how to find the property: naturalWidth inside of an Image Element?

Additionally, does any one have a clever way to use attributes to scan all the images on a page and see if they are loaded? I read that the naturalWidth will be set to 0 when an image doesn't load .. so I am trying to get that working.

Re: Testing control properties

I am not familiar with the "naturalWidth" attribute. You are saying that this attribute exists on the HTML DOM but you can't get to it when you do imageElement.GetAttributes() ? If so, then this sounds like a bug that we should to take a look at that.

So using Chrome - Inspect Element on an Image .. you can see the HTMLImageElement has a set of properties:

Also here is a web article talking about how to check naturalHeight using JavaScript:

Re: Testing control properties

Thanks! I've logged a bug for this. We'll look at it for the next refresh.
