Hi All,

Can you please let me know what is the use of fileupload control in UpdatePanel because normally FileUpload control does not work with partial postback which is done in UpdatePanel and it requires a full postback.

So in order to make this work we use Postback trigger and i would like to know by using this will the whole page be postedback or not.

If no, then using fileupload control in UpdatePanel is useful.

If no, can u please explain how can i achieve partial postback without using Ajaxtoolkit controls.

Thanks.

Prathap.

I did - You have async upload control (upload with partial rendering), but if you have issues(do not want to use it at all!) with it, there are jQuery based upload control that do not need a postback and does the upload 'partially'.
