Hi All,

Iam using fileupload control inside updatepanel, and save button for save the file uploaded by that fileupload to server by below code:

MyFileUpload.SaveAs(Path);

So that, my problem i need to perform this code without refresh whole page, so i don't want to use updatepanel triggers for save button to do postback(it referesh whole page _i need only execute

 SaveAS Code to Server and all i need to  pass the problem of security issues_(not all page refresh and send to server),

 and if the above code don't work if the button don't refresh whole page,

may anyone tell me the code for SaveAs function in Asp.net and how it work to perform the SaveAs function for uploaded file to save it on server.

Regards,

AHF.

 U have to do Full PostBack for Fileupload or may search for a thrid party component

The UpdatePanel and FileUpload do not play nice together, however here's one of many "AJAX" solutions out there:

FileUpload control are not compatible with Update Panel when they are used to upload files as part of an asynchronous postback.

Try to use <input type= "File" id="fileUpload" name="fileUpload" />
