Hi!

 

Please excuse me for my poor knowledge regarding web development and asp.net but I´m wondering if, when using the AjaxUploader, the page really should get reloaded after each added attachment? I have a multiple attachment control and each time I add an attachment a page load occurs. Is this the behavior even when using Ajax?

 

Thanks!

Niclas,

 

Can you reproduce the problems in the following example?

What do you mean using Ajax ?

 

If you are using Microsoft AJAX , it will send a request to server , and change the content of the page.

 

If you use other client side AJAX , such as raw XMLHttpRequest code , you need catch the event and return false :

 

<script>

function CuteWebUI_AjaxUploader_OnPostBack()

{

        return false;
}

</script>

Adam, cutechat, thanks for your replys!

 

OK, so I see. But suppose I use Microsoft AJAX and sending a server request is ok performance wise but I need to distinguish the event generated by the file upload from other events that causes post back so that I can direct my code behind depending on which control that is causing the post back, how do I manage that? The "IsPostBack" property is "not enough" so to speak, I need to know which control is "throwing" the event so that I can act accordingly directly when "Page_Load" occurs. Can I do that?

 

When I have added a "protected void UploadAttachments1_AttachmentAdded(object sender, CuteWebUI.AttachmentItemEventArgs args)" event handler to my code behind this event is catched after the "Page_Load" and because I have code in the "Page_Load" that I dont want to execute when a file upload occurs I would somehow to know that it is the file upload that has caused the new "Page_Load".

 

As you see I don't know anything about asp.net but I would highly appreciate any answer to this "generic" asp.net functionality question.

 

 

EDIT: Achieved the desired functionality using:

 

            string ctrlname = Page.Request.Params.Get("__EVENTTARGET");
            if (ctrlname != null && ctrlname.Equals("UploadAttachments1"))
            {
                return;
            }

 

 Thanks!

Hi,

 

Yes. the Page.Load event will fired when the uploader want to fire the FileValidating event.
