I have a RadUpload in the edit template of a FormView. My desired behavior is
Formview should open in ReadOnly Mode
On clicking the update button, a postback should occur
So the desired transition scheme is ReadOnly->Edit should be Ajaxified Edit->Readonly should be a postback.
I have tried using this post, but I cannot access the update button in my script (as the formview opens in readonly mode).
Any idea how can I get my desired functionality
You can check this online help article which shows how to upload files when RadUpload is inside RadAjaxPanel.

To avoid auto post back I have used update panel covering my asp webpage which is having multiple repeater in it.
Each repeater having file upload control in it. Each file upload is showing me empty file when I am trying to save.
File Upload control faces issues working with updatepanel
so to solve it
define a postback trigger for your control in the updatepanel,
or
if that doesn't work then use AsyncFileUpload control from Ajax toolkit
This is really awkward. I am working on Telerik controls. I have a .NET web usercontrol which have some RadCombo boxes and a newly added RadTextBox. All of this in a RadAjaxPanel and RadLoadingAjaxPanel. When the user control loads, all of the control load values from database, including RadTextBox.
(The problem starts here) And when I try to update the RadTextBox control value and try to submit, I "Always" get the old value of the textbox.
Please check your Page_Load event and verify that you have an if(!IsPostBack) surrounding the code that loads the original values to the RadTextBox.
Recently I was working on a requirement as mentioned below:
There is a webform containing FileUpload control and below it there is a gridiview control.
When user clicks the browse button of the Fileupload control and picks an image to upload the image should now be available in the gridview using Jquery.
The binding of the gridview with the image source from Fileupload control should be done using Jquery.
Can anyone help me out with any code sample.
Thanks In Advance,
Thanks & Regards,

If I'm correctly understand you, the one possible way to implement something similar to this requirement is to place gridview into UpdatePanel and use async file upload control like the AsyncFileUpload from the AjaxControlToolkit library or some else. With such control you can handle it's event fired in the client-side after the file successfully uploaded and call __doPostBack function in that event handler to re-bind gridview on server.
I have the following scenario. I have a page that hosts several user controls. The user controls are all surrounded by a single update panel. All user controls have a save button on them. When the save buttons are clicked the page updates the update panel as expected.
Some of the user controls contain editable list views. Whenever an action is taken on these list views, the Update Panel is NOT refreshed, but the whole page posts back. How can I get these ListViews to also refresh the Update Panel? I cannot post the code because of NDA.
There are no javascript errors on the page reported by either IE8 or Chrome.
Check the autopostback property of the dropdownlist control, if the property is set to true it tries to postback every time the selection changes.
If this does not work for you, you may wish to try implementing manual update triggers in your controls code and setting the update panel to conditional, to firmly control when you want the panel to update.
I have a RadGrid with a custom edit form (FormTemplate). The grid is in an UpdatePanel for asynchronous postbacks, as changing the selection in drop down lists and checkboxes needs to enable or disable other controls on the form. (Updating the controls synchronously is not acceptable to the user.)
As part of the edit form, I have a FileUpload control, but this does not upload the files when in an update panel.
I have tried adding the Insert/Update button as a PostBackTrigger on the UpdatePanel, but this causes an error on page load, as the UpdatePanel cannot find the control (the edit form is not open on load).
Is there a way to add/remove the trigger at runtime when the form is opened/closed?
Or is it possible to have the FileUploads work with the async-postback?
Yes, you have problem with is as FileUpload is in the list of controls that are not compatible with update panel (for more info here). One workaround for you could be swfupload. Another option is to use this jQuery plugin http://www.plupload.com/example_all_runtimes.php as stated here
There is a demo on the Telerik site that shows how to upload the files.
By using a RadAjaxPanel, RadCodeBlock and RadScriptManager with RadUploads instead of FileUploads it is possible to detect on the client side whether files have been selected for upload.
If there are files to upload, the AJAX postback can be disabled during the upload.
