How can I assign a CSS Class to HtmlTextArea elements?

With other elements created in C#, I can use either this type of code:

C#

txtarAccountCodes = new HtmlTextArea
{
    CssClass = "clearonreset"
};

...or this:

C#

txtarAccountCodes.CssClass = "clearonreset";

...to assign a CSS Class to an element, but neither is allowed with HtmlTextArea elements. Is there a way to assign a CSS class to HtmlTextArea elements server-side?

I can set CSS Styles, but setting a CSS Class is a different animal, methinks.

Do you need to style an element or "same animal"? :-)

I don't need to style it, I need to assign it a CSS class, so that the jQuery will act on it in certain circumstances. The link you provided showed how to set up styles, but styles != classes.

You are right, it's not the same. But using a class just for a condition for jQuery sounds pretty pointless. You can use just jQuery for this purpose, without any server-side code. And, among other thing, you can add/remove any class with jQuery. It all depends on what you want to achieve.

To set the CSS class of an HtmlTextArea control, or anything else defined in the System.Web.UI.HtmlControls namespace, you'll have to use the Attributes collection[^]:

C#

txtarAccountCodes.Attributes["class"] = "clearonreset";

Alternatively, you could use the TextBox control with the TextMode set to MultiLine:

C#

txtarAccountCodes = new TextBox
{
    TextMode = TextBoxMode.MultiLine,
    CssClass = "clearonreset"
};
