ASP.NET MVC TagBuilder.SetInnerText () does not set text correctly

So I am creating an extension method HtmlHelper and I am facing a problem when using TagBuilder.SetInnerText (). The helper displays the option tag. Here is the source of the helper:

public static string Option(this HtmlHelper helper, string value, string text, object htmlAttributes) {
        TagBuilder tagBuilder = new TagBuilder("option");

        tagBuilder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
        tagBuilder.MergeAttribute("value", value);
        tagBuilder.SetInnerText(text);

        return tagBuilder.ToString(TagRenderMode.SelfClosing);
    }

In my mind, I call

<%= Html.Option("value", "text", new { }) %>

but the inner tag text is not set and I am left with

<option value="value"> </option>

Any ideas on why SetInnerText () is not setting the text correctly?

Thank.

return tagBuilder.ToString(TagRenderMode.SelfClosing) - is the problem

It tries to deduce <option value="" />

where there is nowhere to insert the InnerText.



Do it:

return tagBuilder.ToString(TagRenderMode.Normal)

I think the correct way to use InnerText

this is below. You need to set InnerText

in Create Tag and after defining additional attributes.



TagBuilder tagBuilder = new TagBuilder("select")
{
    InnerHtml = "set Anything"
};
tagBuilder.MergeAttribute("value", value);
