Access to ASP:Textbox on http handler

I'm trying to use the MultiUpload flash script on my ASP / VB.NET project and, to upload a file (following the instruction available on http://www.codeproject.com/KB/aspnet/FlashUpload.aspx) I created an HTTP Handler. It works fine but, at this point, I need to read a value from a ASP:Textbox available on the caller page. 开发者_JAVA技巧How can I read this parameter?

thanks, Andrea

You will need to pass the value of the textbox along with the request. You could use the QueryParameters property of the FlashUpload control. Inside the upload handler you would then simply read the request value: context.Request["paramName"].

Depends how you're submitting to the handler, but you can pass it in as either part of a query string or in the FormData if you're posting to the server. Then you can access this value in the HttpContext.Request object
