Object must implement IConvertible.

[Michael Foltz]

hey,

I've got a form that attempts to post a boolean value into an action param

-----------------------

 - form:

<form method="POST">
    <input type="text" name="ID" value="$ID" />
    <input type="hidden" name="confirmDelete" value="true" />
    <input type="submit" value="Delete" />
</form>

 - action:

public void DeleteArticle(int ID, bool confirmDelete)

-----------------------

after a bit of testing, I've determined that its a result of a failure to convert the string value "true" to a boolean.
i can change the param type to string, but I'm curious, what's the logic behind which element-types can be implicitly converted to a boolean type?

is there any documentation on this particular issue?

My understanding is that CGI\Form Posts never know what the element types are they just have name and value pairs like a querystring; so this might be a bug. Have you tried using “1” instead of “true” to see if that works?

er.  scratch that.  problem was a result of both a querystring value & form-post value
