+TActiveDatePicker is the active control counter part to TDatePicker control. +When the date selection is changed, the OnCallback event is raised. +
++Please refer to the documentation of TDatePicker for further usage informations. +
+ ++TActiveFileUpload displays a file upload field on a page. Upon postback, +the text entered into the field will be treated as the name of the file +that will be uploaded to the server. The property HasFile +indicates whether the file upload is successful. If successful, the file +may be obtained by callingsaveAs to save it at a specified place. +You can use FileName, FileType, +FileSize to get the original client-side file name, +the file mime type, and the file size information. If the upload is not +successful, ErrorCode contains the error code +describing the cause of failure. +
+ ++TActiveFileUpload raises OnFileUpload event if a file is uploaded +(whether it succeeds or not). +
+ ++TActiveFileUpload actually does a postback in a hidden IFrame, and then does a callback. +This callback then raises the OnFileUpload event. After the postback +a status icon is displayed; either a green checkmark if the upload is successful, +or a red x if there was an error. +
+ ++TActiveHiddenField is the active control counterpart of THiddenField component. +It displays a hidden input field on a Web page. The value of the input field can be accessed and changed +on callback via the Value property. +
+ ++TCallbackEventParameter provides the parameter passed during the callback +request in the CallbackParameter property. The +callback response content (e.g. new HTML content) must be rendered +using an THtmlWriter obtained from the NewWriter +property, which returns a NEW instance of TCallbackResponseWriter. +
+ ++Each instance TCallbackResponseWriter is associated with a unique +boundary delimited. By default each panel only renders its own content. +To replace the content of ONE panel with that of rendered from multiple panels +use the same writer instance for the panels to be rendered. +
+ ++The response data (i.e., passing results back to the client-side +callback handler function) can be set using ResponseData property. +

-+TInPlaceTextBox is a component rendered as a label and allows its +contents to be edited by changing the label to a textbox when +the label is clicked or when another control or html element with +ID given by EditTriggerControlID is clicked. +
+ ++If the OnLoadingText event is handled, a callback request is +made when the label is clicked, while the request is being made the +textbox is disabled from editing. The OnLoadingText event allows +you to update the content of the textbox before the client is allowed +to edit the content. After the callback request returns successfully, +the textbox is enabled and the contents is then allowed to be edited. +
+ ++Once the textbox loses focus, if AutoPostBack +is true and the textbox content has changed, a callback request is made and +the OnTextChanged event is raised like that of the TActiveTextBox. +During the request, the textbox is disabled. +
+ ++After the callback request returns sucessfully, the textbox is enabled. +If the AutoHideTextBox property is true, then +the textbox will be hidden and the label is then shown. +
+ ++Since 3.1.2, you can set the ReadOnly property to make +the control not editable. This property can be also changed on callback +
