FileUploadControl does not work inside UpdatePanel in normal way. The easiest way to do so is to User Ajax FileUploadControl which work in Asynchroneous way.

Hi Dadu Fileupload doesn't work for updatepanel. I got the same problem once. 1. Without updatepanel - it works fine 2. With updatepanel - you have to use postback trigger like this inside the update panel. 3. With updatepanel - You can use ASyncFileUploadControl in AJAX.

Santhosh Kumar Jayaraman · Answer

Just check what is the value inside each property of FileUpload1 while debugging

Dadu Da · Answer

i put as you told you like followed protected void note_Init(object sender EventArgs e) { ScriptManager.GetCurrent(this).RegisterPostBackControl(FileUpload1); } FileUpload1 is ID of ASP:FileUpload but Still i am unable to get the file

Santhosh Kumar Jayaraman · Answer

Its just page_Init..Your aspx name there protected void Page_Init ( object sender  EventArgs e ) { ScriptManager . GetCurrent ( this ). RegisterPostBackControl ( uploadFileButton ); }

Dadu Da · Answer

Santhosh Sorry I wrote you name wrongly I put File Upload in Update panel please elaborate userView

Santhosh Kumar Jayaraman · Answer

Check if you'r using a UpdatePanel if so then in Page.Init do something like this: protected void userView_Init ( object sender  EventArgs e ) { ScriptManager . GetCurrent ( this ). RegisterPostBackControl ( uploadFileButton ); }

Dadu Da · Answer

Dear Santhish I already checked it I do not get file thus how could i check the name of else

Santhosh Kumar Jayaraman · Answer

Instead of if (FileUpload1.HasFile) { try this if (FileUpload1.FileName!=string.Empty) {
