I have got a form in my page which contains a file upload helper and a submit button (and some other controls). My page is working fine and the form can be submitted when browsed by firefox or chrome. But in ie when I press the submit button nothing happens (the form is not submitted to the server). What can cause this browser-specific problem?

推荐答案
If you set the includeFormTag as true in your FileUpload helper, it makes a new form into the form that you have already created.
Setting the parameter to false has the result of removing the unnecessary <form> tag and, furthermore, lifts the upload button that you hide with CSS.
Maybe this is the reason why IE doesn’’t work properly.
