RadAsyncUpload not Asyncronous

[Jaime Weise]

We are Building a Simple Widget
The widget has a designer. The designer has a RadAsyncUpload control. The upload control has a handler for the OnClientFileUploaded event. The event fires when the files selection is complete. The files doesn't upload until I click a button on the designer. The file is only uploaded after the pages is refreshed(posted back). 

Of course the button doesn't post back asynchronously.

Hello,

RadAsyncUpload offers asynchronous upload capability while maintaining the look of the regular RadUpload control.The upload process requires that the files are uploaded to a custom handler and not to the hosting page. Files are stored in a temporary location until a postback occurs.
Please check your project for the following folders "~/App_Data/RadUploadTemp/, the files are stored there(with unique names) after they are uploaded. After a postback occurs the files are moved to a target folder if the TargetFolder property is set.

Best wishes,

Hi thanks that's fine, 

Then, how can I create a postback from the designer class so I don't have to have an and upload, a submit button, and the regular dialog save button (image link)?

Ideally, I could just click save and the postback would happen.

Hi jwize,

Please clarify what do you mean by "designer".

If you want to trigger a postback when is clicked somewhere you can use javascript. Here is a sample code:

<form id="form1" runat="server">
      <a href="javascript: submitform()">Search</a>
</form>

<script type="text/javascript">
function submitform() {
    theForm.submit();
}
</script>

All the best,

The Designer refers to a control that inherits from ControlDesignerBase 
Go to pages and edit a page and click on the edit button of any widget.

When you click on the edit button of the widget in the page content edit mode the designer is shown. That is what I am referring to as designer. The designer is where you set properties for the widget at design time. There is a save button and a cancel link at the bottom as well as an advanced tab.

The save button doesn't post back. 

It would be appropriate if the dialog could postback and then close. I guess the onclose event should be handled and somehow the post would signal for the dialog to be closed once posted back. 

That is just a stab at what I might need to do. Or I could somehow save the temp file on the server to the correct place.

Hi Jaime Weise,

Thank you for contacting us.

Unfortunately it is not possible to handle dialog "closing" event or trigger a postback from the dialog due to security reasons.
Please consult with the following demo how to use a custom handler to save a file directly.

I hope this helps. Please let me know if I can assist you further.

Kind regards,
