Asyncfileupload not working in Firefox

I'm making an asp.ne开发者_高级运维t website, in it I have an Asyncfileupload control which is inside an updatepanel. It works fine in Chrome & other browsers but it doesn't work in FireFox.. Please help..

Try setting the width of the AsyncFileUpload control using css:

Follow below Steps:

• Apply CssClass on ajaxToolkit:AsyncFileUpload like "imageUploaderField"
• Write Css(".imageUploaderField input{width:100%!important;}")

If the result is the same, update your ajax toolkit with the latest edition.

References: AsyncFileUpload with Firefox 22.0b1

If it still doesn't work then it could be a Firefox bug.

yah but for that you should check it in codeplex, there is some some javascript changes..
